Hey All,

I was very easily able to get the Solaris 20.0.688 ocean procedural node and workflow working with Renderman 26.1 with the help of some great people in the technical forum. See this thread https://www.sidefx.com/forum/topic/95413/ [www.sidefx.com]

Things that work:
1) Renderman renders with the native mtlxoceansurface shader.
2) Renderman renders with a custom Renderman PxrSurface shader.

Things that don't work:
1) Renderman can't render with the default mtlxoceaninterior shader. I think it is because there is an kma_volume node in the shader... that is a hybrid node (Karma/MaterialX).
2) I can't render a foam bgeo.sc sequence.. foam doesn't work with RenderMan <-- This is the big reason I am here.

Is there a workaround for these limitations?

Thank you so much... it works like a charm...

Best Regards,

Todd

Can you share a node tree on how you plugged into a 3rd party hydra delegate? I have the ocean shader working with Renderman, but it is a little dicey <---no pun intended :-) It is very janky. I have to have 2 rendersettings nodes in order for it to work. I got some help from Pixar on this.. but even they said it was a little janky to get working. Are we missing the correct workflow for 3rd party delegates and the ocean procedural tools?

BTW, if I don't included the karma render settings node, I get the following error:
Warning: Ocean Procedural could not dice geometry due to missing Camera primitve. Please ensure a RenderSettings with Camera has been defined.

Thanks for any help with this,
