Hi noticed this in the release

"Lama nodes exist in this version of MaterialX, but they are not fully functional. Until Lama is completed, the equivalent Houdini nodes are hidden, to avoid confusion."

I there ant was to access the nodes despite them not being fully functional.

Best,

Brilliant, Thanks mate!

Hi, what features are missing compared to Renderman for example? Also do we need to wait for H20 for Lama to be rolled out or is this something a new build can provide as well? Honestly, I´m exited, I like Lama a lot :-)

It's going to depend on the MaterialX team finishing the implementation. As of right now, the Lama nodes are defined but all they do is pass along the reference BSDF with no actual layering, from what I understand.

If MaterialX releases working Lama nodes prior to H20, they might make it into 19.5, but it's by no means guaranteed. Updating a third-party open source product in a revision build is chancy, especially if it comes with significant new features.
