Hi Francois, The current logic to add in "default" `geominfo` resolving is [here]( https://github.com/AcademySoftwareFoundation/MaterialX/blob/main/source/MaterialXCore/Element.cpp#L422-L436) When you create a string resolver you can optionally pass over a `geomInfo` name to use....

A name with `__` in the middle of the name fails. I believe `__` at the start of the name is okay. Would be a pretty easy fix to add...

Hi @seb-mtl, Thanks for tracing this through. This was written a long time ago for command line testing (and wasn't ever wrapped through a Python wrapper) so would need to...

Hi Damien, This is most likely due to assumed "usage". This utility is used to get the MaterialX `document` version of which the patch version in a `major.minor.patch` string only...

This sounds like a good idea to not-prefilter the patch version number in case it's desired. I want to double check this is true: 1. A Document write will not...

Full sample file added: [channels_attribute_failing.mtlx.txt](https://github.com/AcademySoftwareFoundation/MaterialX/files/9294675/channels_attribute_failing.mtlx.txt)

Seems the issue is that the "channels" attribute string propogates between sockets for inputs but not for outputs proper, except the final output socket.

From a rasterizer support point of view, code generation has been added. A sample renderer was started, but no active work is being done currently. Color management support I don't...

Hi @fire, I assume this is the related [project](https://github.com/godotengine/godot-proposals/issues/714 ): ? Sorry if this is a bit long-winded but I'm not sure of the final intent and not familiar with...
