A free and open source human generator integrated inside Nvidia Omniverse

Hi there 👋

humangenerator's Issues

Comments for code

Severe lack of comments in the code, especially considering we want others to be able to read and reuse parts of our code for their own purposes.

Think of the pain it took to write this extension, don't do that to others.

Extension starts closed

Extension window should be visible by default

Add checkbox to toggle update on release

Async for pip on first install

The pip installer takes too long, users don't know if it crashed or not.

The pip install can be moved from toml to the extension itself, so on enable it checks if makehuman is in path, otherwise run in async showing it is being installed. Message: Installing components may take a few minutes . Similar to downloading the assets.

Add materials/skins API

Right now skins from MH cannot be applied through our extension. Giving direct access to MHAPI would solve this, but further tie us to MH in the future.

Allow editing multiple humans

Downloading assets needs a loading indicator

Currently, you can only see progress if "info" is enabled in the debug console

Droplist widgets / models are no longer used

They should be removed for clarity

Add support for undo/redo stack

Mesh breaks when updating skeleton

We have tried changing from Creating attributes to Getting and Set() when the already exist on this branch https://github.com/cadop/ov_makehuman/tree/mesh-fix but continued to have issues.

Currently we modified the code to delete the mesh and rebuild the skeleton at the end of the process, which is working enough for demos. However, this stops someone from:

• editing their human after making it
• switching rigs
• posing character while editing

Our latest updates on main are from the mesh-fix branch, with some modifications to only build skeleton at the end.

We are not sure what is causing the mesh to break, but rebuilding the skeleton each time we update the mesh is problematic and takes too long for a good user experience. The current slow processing is also on the makehuman side, so updates to USD being faster won't help us.

Materials should be added in "Looks" scope

This would match omniverse convention

Browser assets are not automatically included

Host and download assets (skeletons, proxies) outside of git to speed up install

Note from Jen_B@NVIDIA:

async with session.get(download_url) as response: So this would be when you are downloading content from the given url. Inside you would get each chunk until the download is done. Then from there you would want to check that the response is ok and set the destination to write the file. You can also look into how Sketchfab does there _download() functionality

Clean up resolved TODO comments

          This is resolved. I'll make an issue to clean up the TODO comments

Originally posted by @Fruity-Grebbles in #61 (comment)

modifier images look terrible

Separate UI windows

New humans inherit the previous skeleton

Clothing / Proxy assets cannot be downloaded

Attempting to download assets via the context menu in the asset browser produces the following error:

2022-12-09 15:19:24 [Error] [siborg.create.human.browser.downloader] [access denied: https://download.tuxfamily.org/makehuman/asset_packs/makehuman_system_assets/makehuman_system_assets.zip

Assets appear to no longer be hosted at this address.

Editor window should be inactive when no human is selected

To prevent lost modifications, confusion, and user frustration, the panel should be locked when a human is not selected.

"New Human" button hangs and prevents use of modifiers

Make game engine skeleton default

On refactor branch. It works better with animation retargeting

Why aren't floatdrags as responsive as those in omni.ui_doc?

Double-click timing must be very precise compared to that in the documentation/examples

Docstrings

We need docstrings and type hints for functions, at a minimum.

Doctests using examples parameter would be beneficial, but at least for some of the main calling functions this would be good.

OmniSurface for skin materials

Use OmniSurface (maybe an OmniSurfacePreset Skin?) instead of OmniPBR when adding materials to humans in the scene.

OmniSurfaces look much better.

Use smooth human mesh

Instant update checkbox non functional

In refactor branch

Humans swap clothes

Updating humans inherits the previously selected human's clothes + proxies

reset character button

Some proxies should make mesh hidden

For clothing we want to keep the underlying mesh, but other proxies require the mesh below to be culled. Should have a user selection/option for proxies that enable this.

Selecting elements of human prims should reference their human

Eg. selecting a human's mesh should allow a user to modify the corresponding human

Pose storage

Omniverse does not natively support storing poses manually configured by manipulating skeleton joints, as it considers them "transient prims." As pose control has been a desired feature from users, we could add this. There are several approaches of various degrees of integration.

Store custom prim data for poses
Extend USD schema to allow manual posing
Saving PreviewSkelAnims currently created to display transient state

(potentially out of scope)

Add slider icons

Some sliders have unclear function. Add images to show what they do.

Skeleton not Binding to proxies

In refactor branch

optimization (stored imports)

Optimize load times by caching loaded data

Making a new human removes the previous human's proxies

Refactor

• Create Skeleton Class
• Create Human Class
• Separate inits

Human clothes sometimes stop deforming with targets, despite staying rigged

Steps to reproduce unclear. Recommend examining reset functionality.

API example for generating human

We need an example of interfacing with the extension as a class so that someone can generate people through python, e.g. a script to generate many people with a specified range of attributes.

Fetch icon assets from inside of Makehuman module

Modifier label images are included twice, both within the makehuman module and in the data/ folder in the extension.

Asset browser "Remove collection" crashes Omniverse

Consider disabling for default collection

Local variable 'selection' referenced before assignment

UI does not reset when creating a new human

Add extension to menu

If the UI tab is closed, it cannot be reopened without reloading the extension. Add it to the menu bar to give users the option to restore it

Make proxies deleteable

Non-macro modifier values don't update in UI

When selecting a human, the macro modifiers are successfully loaded in the modifier parameter panel. All others are not.

UI needs default width and height

Removing proxies should remove their prims

Remove extra letters of the file extension from asset names

Editing modifiers in "realtime" is UI blocking

Prudent to use async and get locks on prims

Proxy removal fails when proxy type is not specified
