MaterialX Needs a Single-File Container. Let's formalize what @polyhaven.com and @gpuopen.bsky.social material libraries are already doing with a new "mtlz" extension. Details here: ben3d.ca/blog/materia... CC: @materialx.bsky.social

MaterialX Needs a Single-File Container
MaterialX assets are multiple loose files, which breaks down in real pipelines. The community has already solved this with zip packaging. We just need to formalize it as .mtlz.
