MeshSync DCC Plugins

MeshSync DCC Plugins

MeshSync DCC Plugins is package that contains plugin binaries of DCC tools for using MeshSync, which is another package for synchronizing meshes/models editing in DCC tools into Unity in real time. This allows devs to immediately see how things will look in-game while modelling.

Features

	Maya	3ds Max	MotionBuilder	Blender
Polygon mesh sync	✔️	✔️	✔️	✔️
Camera sync	✔️	✔️	✔️	✔️
Light sync	✔️	✔️	✔️	✔️
Double-sided Mesh	✔️	✔️	✔️	✔️
Negative Scale	🔺	🔺	🔺	🔺
Multi UV		✔️		✔️
Scene Cache Export	✔️	✔️		✔️
Non-polygon shape
Bidirectional Sync				✔️

Caveats

• Negative Scale: partially supported on some DCC Tools.
  If all XYZ values have negative values, the mesh will sync properly, however if only one axis has a negative value, Unity will treat the mesh as though every axis has a negative value. Certain DCC tools may have Bake Transform option which can sync the mesh in this case, but it will lose any deformer information.

meshsyncdccplugins's Issues

Can't find poco - building plugin for Maya 2022

Hi,

I'm trying to build MeshSyncDCC plugin for Maya 2022 on windows but i'm blocked at this command line :

make_meshsync_dcc_plugin.bat MeshSync-0.9.0-preview -DBUILD_MAYA_2022_PLUGIN=ON

It gives me the following message :

Apparently, it can't find poco, even if Poco_DIR is in my path.

If you have any idea what I might have done wrong, that would be very helpfull. I have been stuck on this for a long time.

Thanks a lot

thanks a lot.

How can i get texture sync from Blender in Unity?

How can i get texture sync from Blender in Unity?
Blender 3.2/Unity 2022.1.15f1

Blender 4.0 not suported

if i press sync blender crash

Installed the MeshSync in unity(verson 2021.3.6f1c1 lts), but can not find the UI in toolbar

May I ask when MAX can be transmitted to Unity to support synchronized Alpha?

When my model was synchronized to Unity, the Alpha channel was changed to 1. I want to be able to synchronize the Alpha data.

Will support blender cycles render?

Transferring issue from: unity3d-jp/MeshSync#9

Hi, i like this addon and i'm a blender user.
Current released light is only support blender render?Will support cycles default emission node light?
And will support Cycles Render Principled BSDF Node?I think it maybe easy bake to standard shader.

Finally,I hope support NLA.NLA is a good idea, it can make animation clip easy.
NLA like this.

maybe it sync like this.

I like this addon and Good luck!

Sync visibility state of objects?

Hi,

I am wondering if there is any plan to add support for visibility (enable/disable) state of objects. It seems like good feature to have given the lack of support for grouping or selected object sync?

(I used Blender plugin only, not sure about other DCC)

Thx in advanced.

Cant get motionbuilder 2019/2018 to work with Meshsync

Hi Unity.
Im trying out Meshsync, creating an AR application with normcore sdk and meshsync.
It works great with blender but I need it to work with Motionbuilder .

Im having issues not being able to connect motionbuilder to Unity.
Plugin is offline in motionbuilder see picture1.
The motiobuilder plugin is not showing up in unity Preferences.

Any ideas how to fix?

Best regards
Herman

Blender Crash on AutoSync or ManualSync

When I click on autoSync or Manual sync blender crash immediately.
The mesh sync server works, I checked with this address : http://127.0.0.1:8080/
I don't have any error in unity console.

I tried with different version:

• MeshSync (0.7.1 or 0.6.1)
• Blender 2.9.0 / 2.9.1 / 2.91.0
• Unity 2019 LTS / 2020.3 LTS

I test with my current project, and also new project.

Could compile motionbuilder 2022 plugin for meshsync

We have done a lot of work on mobu2022. can not change mobu version.

very appreciate to compile motionbuilder 2022 plugin.

Thanks a lot

add 3ds Max 2022, 2023 SDK and future versions compatibility

I added 3ds Max 2022, 2023 and possible future versions compatibility to my fork of the MeshSyncDCCPlugins
i also added some filtering code to the CMakeList to only create the build folders for actually installed 3ds Max SDKs
As this is the first time i try to contribute to the upstream of a public github repo, i'm not exactly sure how and where to procede from that. I know i should create a pull request, but first i wanted to be sure that this is even a wanted contribution .

Any more head ups would be welcome .. thanks!

Blender light intensity vs Unity

Is there a reason why Blender 3.0's light intensity is mapped to 1/1000 of unit in Unity URP?

eg. Sun light with Strength 1.0 (= 1 W/m^2) is somehow mapped to 0.001 in Unity URP when light is synced.

Blender MeshSync DDC "Failed to Install" - It was installed but not detected.

Mesh sync auto-installation said it "failed to install" the plugin, only it did install. However no Sync can be established.

Why supports only Standalone Build?

We are developing android games. And we would like to use mesh sync. Will Android build support come?

Roadmap: DCC Tools Support

Possibly be done in the future

• Houdini
• Cinema 4D
• Photoshop (texture and screen painting)

Done

• Modo
• VRED
• Motion Builder
• 3ds Max
• Maya
• Blender
• xismo
• Metasequoia

Gave up

• ZBrush
  • no plugin API and it's software rendering (= impossible to snoop vertices)

BlenderでShapeKeyを変更してもUnityに反映されません

Transferring issue from unity3d-jp/MeshSync#112

失礼します。

動作環境 : Unity 2019.2.9f1
Blender 2.80

上記の環境ですとShapeKeyの反映が正しく行われないようです。
例)
1.Blenderで単一ボーンをつけただけの立方体を用意します。
2.適当にBase以外の ShapeKey を作って変形します。(Keyの名前をKey1とします。)
3.Unity側に MeshSync します。この際 BakeModifiers はしません。
4.Unityで Key1 の変形が正しく反映されてるのを確認します。
5.Blender側に戻り、Key1 の形状を変更してUnity側に MeshSync します。
6.Unity において変更が反映されていないのが確認できます。

Blender2.79 を使用していた時は正しく反映されていたのですが、更新してから反映されなくなりました。
こちらご調査お願いできますでしょうか？
よろしくお願いいたします。

Syncing lights spawned by Blender GN

It looks like syncing non-mesh object created by Blender Geometry nodes are not currently possible.

A possible use case is using GN to spawn a bunch of light instances, MeshSync doesn't appear to handle that as of 3.2.2

Motion Builder not detected automatically and manual add not possible

In preview version 0.8.0 both my 2019 and 2020 Motion Builder installations are not auto-detected. Trying to manually add them by pointing to the folder containing the installation or binary files of Motion Builder brings up a error message that says no DCC detected.

MacOS Update Needed for Blender 2.93.6 Please!

.zip files included are only up archived Blender release 2.93.4 which installs but cannot be activated?

how can i change adress or other checkbox option in motionbuilder use python

is there any way?
Thanks~

Blender Plugin doesn't seem to work

Hi, I tried to install the Blender plugin of MeshSync on version 2.81 and 2.82a and it doesn't work I guess. Should I see the object at least in the browser under 127.0.0.1:8080? Or if there's a Unity problem, browser won't display it (the object from Blender) (because Unity hosts/creates the server?)?

About installation of Blender

Transferring from unity3d-jp/MeshSync#134

Even if 20190902.zip in MeshSync is put in Blender, it doesn't react.

When unity_mesh_sync.py among 2.8 folders of Plugin~/MeshSyncClientBlender/python/ is put in, it's transcribed in an add-on, but an error can't go out and use it.

MeshSync Blender DCC Plugin not working on M1 Max Macbook

Can not enable/install the Blender MeshSync plugin on my Macbook with the M1 Max chip.

Support for adding custom python code to run during the sync process

Hi!

More of a question. Would it be possible or is it currently possible to run custom python code during the sync process? Similarly to how the "Bake Transform" or "Apply Modifiers" works, but with custom python. I'm trying to convert attributes created within a geometry node to a UV set so that the generated mesh can be properly used in Unity.

Supported version is like 3years old...

Doesn't work on 2023.3 no mesh sync preference option

Also Blender is 4.0 now ..can please update these for newer versions.

Plugin .zip downloads removed???

Hi.
In your docmentation for setting up MeshSync for Maya, you link to the releases section to download the Maya plugin.
I dont see DCC plugins downloadable in the releases section.

This suprises me because I thought I had downloaded the Maya plugin from here belore???
Please help.

Roadmap: Blender

• fix visibility handling
• fix parent handling
• add 'bake transform' option
• fix auto sync
• improve detecting updated objects (bpy.app.handlers.depsgraph_update_post)
• use render meshes (Subdivision modifier has both render/viewport iterations)
• fix bone handling (can reproduce by tree_creature.blend )
• handle textures
• materials
• multiple uv support (unity3d-jp/MeshSync#92).
  Example:
  Blender UV0 = DetailMapUV's = Unity UV0
  Blender UV1 = LightMapUV's =Unity UV1
• send preview mesh when editing
• greasepen
