H20 Material Library

[Dan Andersen]

In the Houdini 20 docs it's stated that the Material Library workflow changed in H20: https://www.sidefx.com/docs/houdini/...allibrary.html

In Houdini 20, the Material Library LOP’s way of creating materials changed fundamentally. In previous versions you could access all shader nodes from the libraries root level. This often lead to confusion, because it was possible to mix incompatible shader nodes. Now, shaders are created inside subnets:

• Karma Material Builder
• USD MaterialX Builder
• VEX Material Builder
• USD Preview Material Builder

The new approach also filters the nodes in the Tab menu and it’s, for example, not possible to add MaterialX nodes to a VEX subnet.

When inside a Material Library LOP I can't seem to find the V-Ray Material Builder (or any other V-Ray node) in the Tab Menu, so wonder if this new workflow is supported yet?

Thanks,
Dan

Dear Dan Andersen, hello.

Please open the Tab Menu and add vray to the list.
Take a look at the example here:

And when you open the Material Library, you will see the V-Ray tab as well.

Best regards,
TS

Thanks, Tsvetomira - that worked

Btw, is this a temporary solution - the user having to manually add this string - or is that just how it is now?

If SideFX won't add some way for this to be configurable - this will be the only way.

I see, thanks for the info..
