godot_game_tools's Issues

animations are not added?

When I try to add animations in the blender it turns out successful but does not display in animation list.I get this error when the bone name changes so the armature:
`Traceback (most recent call last):
File "/home/mycomputer/.config/blender/2.83/scripts/addons/src/panels/character_utilities_panel.py", line 74, in draw

Animation Problems

Hi, i have some troubles with the exported GLTF file.
I am sure that i made all settings like in the video DEVLOG #4 . (I checked it twice)
The Animation Loop is not set in my Godot Project and i have no way to fix this in Godot. When i set it manually it changes back as soon as i restart Godot.

I also have not the option for the animation tree presets in blender as shown in the video DEVLOG #4:

I´ve tried different "Godot Game Tools" versions, one from itch.io and also that from GitHub.
I work with Godot v3.2.2 Stable, Blender v2.82 and i use the "Y Bot" character from Mixamo and a few animations.

Maybe you have a solution for my problems?
Best regards,
Martin

Latest itch release version not loading in Addons list in Blender v3.0.0

The current version of this addon (at the time of this post on 2/5/2022 Saturday) doesn't seem to be compatible with Blender v3.0.0, however version 2.0.4 does work in Blender v3.0.0. The current version on itch won't show up in the Addons list even after install in Blender v3.0.0. I solved this by using v2.0.4 of your addon instead.

Error while initializing character

Whenever I try to initialize a character or import an animation I get the following error and can't proceed further.

Python: Traceback (most recent call last):

Based on the error message I checked out the frame_range value and realized that it's a Vector2 with float values.

So I tried casting the resulting item to int (e.g. bpy.context.scene.frame_end = int(bpy.context.object.animation_data.action.frame_range[-1])) wherever I could, which did make the errors disappear, but unsurprisingly, every single animation had a duration of 2 frames afterwards.

I tried different Blender versions (3.1.1 and 3.1.2), different addon versions (2.0.4 and 2.0.5), and different models/animations (Y-Bot and Erika Archer), but nothing helped.

I don't know any Blender scripting so I have no idea what value frame_range should normally have and why it doesn't now, but if you can point me in the right direction I can try to find the solution myself.

P.S.: I'm aware of a similar issue at #55 but that's closed without any followup, so I decided to open a new one with more details, hope it's OK

Add a project license

The repository currently doesn't seem to contain any license. Could you add one, please? See Choose a License for more information 🙂

Note that Blender addons generally choose to use "GPLv2 or later" as a license, since this is the same license as Blender.

Add Rootmotion Bone Broken in version 2.93.0

Root Motion Bone is not being added in the correct place. Also there is some error when I click on Add Rootmotio

all animations are centered on hips

Hey. I have been using this amazing addon for a while and have one problem that I can't seem to solve.
In mixamo I have an idle animation where the character leans left and right.
If I import the .fbx of just the idle animation into blender without the addon it works fine.
But with godot game tools when I combine a few animations,
the animation becomes centered on the hips when it should be the feet.
So instead of the character leaning, the feet just slide left and right. It looks crazy.

I tried experimenting with the root animation settings but can't seem to fix it. Do you know of any way I can fix this?
Please let me know if you need any more information or a file example. Thank you!

V2.0.5 Texture Baking bakes lighting (And it shouldn't)

"Create Bake Texture"->"Bake Texture" bakes in the lighting for procedural generated textures. This should not happen as the Godot engine should add the lighting itself.

Furthermore, baking should optionally bake normal maps and specular maps independently.

Initialize Character only imports one Mesh

Using the Y Bot from Mixamo for Initialize Character, only one of the two meshes gets imported.
When I click on Join Armature Meshes I get the Error: `Object 'Alpha_Joints' can't be selected because it's not in View Layer 'View Layer'!

Is there any recommendation on how to fix or use the tooling?

Godot Addon - Create Armature Setup / Create State Machine Error

Hi,

I am using the Godot plugin and I am getting the following error with the Create Armature Setup / Create State Machine functions:

Armature Setup:
res://addons/godot_game_tools/scripts/ggt_main.gd:49 - Invalid get index 'rootmotion_bone' (on base: 'Dictionary').

State Machine:
res://addons/godot_game_tools/scripts/ggt_main.gd:167 - Invalid get index 'state_machine_node' (on base: 'Dictionary').

I was following the DEVLOG #4 video. I noticed that in the video you are selecting a .json file within the Godot plugin, however my Blender export created a .char file.

I am using Blender 2.83 and Godot 3.2.2 stable

Otherwise great work,
Best Regards

Character's animation from mixamo stay in place and in air (wrong shift) in version 2.11.

Every animation exported as loop

Hello! Loving the tool but I found an issue.
First of all I got the character from mixamo with a bunch of animations, some of which I wanted to loop other not.
I had already added -loop suffix to the ones I wanted before hand.
I then followed the workflow in blender and everything look fine.
When I exported the .glb character with all the animations and then opened the animation player in Godot, the -loop suffix was added to every animation.

Not a huge issue because I can manually un-loop the animations I want from inside Godot, but just wanted to let you know.

Instructions are outdated

Hey there, would love to use the plugin but I'm unable to figure out how to use it properly. All tutorials are outdated as well as official instructions.txt. Would love to see the official documentation updated! Thanks!

Imported animations - all over the place

after updating to 2.0.5 I was able to initialize my maximo character without any issue. But when I go to join the animations I have an issue. I select all the animations I want, they all load in but at different x y z coordinates, and when I play them the armature flys around in strange loops.

Feature Request: V2.0.5 When exporting models, temporarily connect image texture instead of procedural texture

Feature Request: V2.0.5
This is a 2 in 1 feature request that are very close in nature.

1. Allow exporting of any model instead of just Characters
2. When exporting GLTF via Godot_Game_Tools, the image texture node that is automatically generated via the "Create Bake Texture" button should be automatically, and temporarily, connected to the "Principled BSDF Shader" node. The implications of this are that the gltf model will now be fully ready for importing into Godot with both textures and animations.

Join Animations Messes up Previous Animations

Basically, upon joining another animation, the previous animations are moved up off the ground, and their feet are not longer planted and the feet float.

Join animations after exporting character creates new armature and gives runtime error

Steps to reproduce:

1. Initialize the character.
2. Join some animations to the character.
3. Export the character to fbx.
4. Join some new animations to the same character in blender.
   Screenshots
   
   I moved the armature to all the collections still the error shows up.

Join animations imports all files in the folder

Import should use only selected files.
How should be duplicate animations be handled?
Ignore, warning or just rename second with Animation_#?

Incorect animations

Animations used (contains T-pose fbx): https://drive.google.com/file/d/1UU2CG0hc_18VK7attN3QSEiWu0M7-HLQ/view?usp=sharing
GGT version 2.0
Blender 2.82

To reproduce:

1. Open Blender
2. Initialize Character -> Select T-pose fbx
3. Join Animations ->Select all except T-pose
4. Wait for it to finish then check out the created animations

Additionally, there's some kind of facial animations that I didn't download from Mixamo but somehow appear in the final animations? Not sure where they came from...

Different issues with Mixamo characters

First of all, great tool for me to use as a non-3D artist. This makes life much easier to use some basic characters and animation in Godot, but...

I encountered some different issues when using your tool in combination with Mixamo animations and after spending some time, I have come to the conclusion to ask for your help. I am using Blender 2.90.1 and the Godot Game Tools version of 12 september 2020. The issues below occur with all of the characters and animations I downloaded from Mixamo (download as FBX Binary with Skin).

Issue 1 – Eye dropper tool no longer in UI
This is more like an outdated functionality, but in one of your tutorials you use the eye dropper tool to select the armature and mesh on which the animations will be applied. After spending some time on Youtube and clicking around, I found out that this ‘eye dropper tool’ is no longer part of the current interface and the armature now needs to be initialized using the ‘Initialize Character’.

Issue 2 – ‘Initialize characters’ only imports one mesh
When I use the ‘Initialize Character’ importer, it only imports one mesh of the armature, see image below. But when I import the FBX using the Blender import-functionality it loads armature and mesh correctly. This is the same issue as [ https://github.com//issues/30 ]. I tried your advice to join the meshes to a single body piece (using CTR+J in Blender – but I did not do any re-rigging).

Issue 3 – ‘Initialize characters’ using one single mesh results in wrong orientation
After creating one single mesh character, I use the ‘Initialize character’ again. But now the T-pose is oriented differently and the scale is much smaller, see image below. However, when I import this FBX using the Blender-importer, again everything looks fine. This is the same issue as [ https://github.com//issues/22 ]. I am able to fix the orientation and the scale, but then I get an issue with the animation.

Issue 4 – Animation is going all over the place
When I click ‘Join animations’ one a single mesh character with a corrected orientation, the animation causes the character to move all over the place. There isn’t a single animation that hasn’t caused this problem for me. I found a Youtube video that explains that the cause of this issue is the hip placement [https://www.youtube.com/watch?app=desktop&v=6SegCO3cZZE]. By selecting the hip armature ‘bone’, then open the graph editor and disable the X and Y displacement, the character stays in place and the animation seems to works fine. But I need to do these actions over and over again for each animation. When I want to apply a second animation, I need to do some other things that are explained in this video [ https://www.youtube.com/watch?app=desktop&v=3Hk9ljcS1Ro ]

All together, this still takes some time for me to get everything working. It is still quicker than doing everything from scratch, but it doesn’t give me the feeling that I am utilizing the efficiency from this tool for which it has been created. Is there perhaps some crucial step that I am missing in my work pipeline?

Bug: "Save Current Texture" only saves out a black texture. V2.0.5

"Save Current Texture" exports a black texture. If I save the texture manually, the proper texture is saved out.

Running Join Animations a second time messes up existing animations

I tried this with multiple models and very simple ones as well.

Steps to Reproduce:

1. Initialize Character
2. Join Animations and select a batch of animations. These will import correctly.
3. Join Animations a second time and select a new batch of animations. Any existing animations will now be bugged and it will appear as though the hips are locked on the Y axis. This is most noticeable with animations like a "fall" or "jump".

Temporary Solution:

• Import ALL animations at once. (This is fine for now, but it would be nice to be able to import in batches for performance and testing.)

Wrong switched position on legs for combine animations Mixamo

If I open the fbx only, the animation seems correct.

Note, the animation TPose from Mixamo that I uploaded still has its old animations.

Steps:
Download TPose and animations
Initialize character with TPose
Combine animations selecting all animation fbx files, no skin

Initialize Character: Not loading all meshes

I followed the latest youtube video I could find and followed along using the same model from Mixamo (Skeletonzombie T Avelange). This worked as expected.

When using a model with multiple meshes from Mixamo (Knight D Pelegrini), only the "Lower_Armor" was imported. This particular model, when importing using Blender's FBX importer, has 3 meshes ("Body", "Head_Hands", "Lower_Armor").

Generate Root Bone error location: <unknown location>:-1

After i try to get get a Root Bone I get that error, what exactly is the issue?

Python: Traceback (most recent call last):
  File "/Users/soxx/Library/Application Support/Blender/2.93/scripts/addons/src/operators/rootmotion_controller.py", line 322, in execute
    fCurveBone = channel.data_path.split('"')[1]
IndexError: list index out of range

location: <unknown location>:-1

When i look into the ARmature i can see the root bone but is a strange direction, and after i import that into Godot and set everything up to use the root bone it just played the animation normally without the correction from the engine.

Renaming an animation sometimes renames the wrong animation.

Renaming an animation sometimes doesn't rename the currently selected animation but instead renames a different one.

The bug is not always replicable.

Init Character is not currently removing previous armatures and meshes once it imports T-Pose

Branch: Dev
Version: 1.0.4
Description: From a blank project, click Init Character Button and choose the folder with animations and T-Pose in place.

Join Animations automatically use root motion

After join animations models don't move like on mixamo in other words It's stay in place. We should let user decide should or not enable root motion. When import model to Godot engine we use AnimationTree RootMotion instead.

What happen
on addons setup, specifically when going to enable the plugin.

The Error
after click checkbox (to enable), blender suddenly show the follwing error:

The Temporary Solution
open the terminal and access the Blender's addons folder, then create new folder named godot_game_tools, then rename from godot_game_tools.py to __ini__.py and move it to godot_game_tools folder.

Hello Guys

This is for the Dev Branch!

I have two issues from the Initialize Character function:

Steps to reproduce:
1.) Load up a blank scene.
2.) Click Initialize Character
3.) Select a mixamo character: (I tried both an animated character and a character in TPose Only)

Can't enable the add-on, after installing

Hi,
I am using blender 2.79, 32-bit windows
I have installed the Add-on from file as directed but when enabling, I get this error in addon_utils.py enable function
and also in _init_.py GGT_AddonProperties_GGT class.

Please help me out. 🙂

Please add an option to only export certain objects from a specified collection

I do not want to see the PistolArmature in the export.

Maybe add an option to only export items in a given collection? (in my case it would be the CharacterCollection)

Initialize Character - Import T-pose in wrong orientation

Hello

This is for release 2.0

When i'm initializing character, the model with base t-pose (exported from mixamo) have some weird orientation.

The same fbx model imported in Blender by File->Import is oriented correctly.

Here is blender file with rig, exported fbx from blender and exported fbx with tpose from mixamo.

Error when adding root motion

The following pops on the Blender Info Log:

Python: Traceback (most recent call last):

TypeError: Scene.frame_set(): error with argument 1, "frame" -  Function.frame expected an int type, not float

And also, when you join an animation that has movement baked in (like the walking animations on Mixamo when the option "In Place" is turned off), for some reason the plugin removes that movement and makes the animation in-place, this should not happen.

I'm running Blender 3.2.1, with Godot Game Tools plugin version 2.1.0

Can you make a version for Blender 4.0.0 version >

`Pose` object has no attribute `rotation_mode` (Mixamo)

Blender: 3.0.0

1. Initialize a character with from mixamo
2. Add animations
3. Add root node
4. Export

The following error is shown:

Locomotion Pack.zip

No Export Options

I just downloaded the latest version of Godot Game Tools, and after figuring out why it wasn't installing (just needed to dig out the other zip further into the initial zip)... I seem to have no new export options whatsoever.

Root motion not working properly

Adding root bone makes model jerk down a bit on start of animation.
Also Z-axis should be ignored by default.

Creating new animation by hand without using "Join Animations" button through plugin does not show animation in Godot Game Engine

I created my own custom 2-frame animation called "Aim Test". I see it in the NLA editor and in the plugin animations list but when exporting to the game engine through the plugins export button I do not see the animation I added in the game engine.

Initialize Character - Selecting an existing armature in the scene, then importing causes error

Dev Branch windows 10

Steps to reproduce:
1.) Have a mixamo character FBX loaded into Blender.
2.) Select the mixamo character armature
3.) Press Initialize Character
4.) Select another mixamo animation from the File Browser and Submit

Notes:

• All fbx import options are at blender defaults
• When this error happens, only the body of the character disappears. I believe this is the case because the mesh body is the first mesh in the array to disappear since all the meshes in the Armature array is sorted alphabetically.

v2.0.5 still import only 1 mesh

Hello, for some reason for me v2.0.5 still only import 1 mesh. I did change the source code and now it works. but I'm wondering if it's save to do that.
I've modified from this;

    if characterArmature != None or characterArmature.type in ["ARMATURE"]:            
        bpy.data.objects[characterArmature.name][armature_key] = armature_key            
        if len(characterArmature.children) > 0:
            for mesh in characterArmature.children: 
                bpy.data.objects[mesh.name][armature_key] = armature_key

into this;

    if characterArmature != None or characterArmature.type in ["ARMATURE"]:
        for mesh in characterArmature.children: 
            bpy.data.objects[mesh.name][armature_key] = armature_key

Will someone tell me if this is fine and won't cause any problem? I'm new to programming and was changing the code just to make that one feature work.

p/s sorry if I shouldn't be posting here, never use this website before.
