Octane lacks procedural texture capability ? ( 3ds Max )

Hi Rico_uk,
vertex color is not an Octane Render map node, so I would like to understand how you would use vertex color in Octane, your specific goal, to undestand if it will work properly in Octane Render .

Hi Paride,
Pretty much the same as the post recently here: viewtopic.php?f=27&t=63667
It'd be great to be able to use vertex / channel data, so for example I could bake an alembic mesh with vertex information for age, velocity, etc. and then use that to drive an Octane shader. Plugging Max's vertex color texture into the RGB material Standard Texture slot works well, expect for the yellowness. This is best scene with a plain white vertex colour, it renders yellow.

Would be really great to get a reply on this, the interesting thing is that when Max's vertex color texture is plugged in to the standard slot on an octane RGB texture node then it works regardless of the UV layout. So it's working really well.... it's just yellow?!

Hi Rico_uk,
I sent the request to developers about the opportunity to use vertex color and / or fixing it.
I hope to give you an answer asap.

Great, another really interesting thing is that vertex data survives being exported to an Octane Proxy and then rendered, could be really really useful

Hi Rico_uk,
Yellow color of vertex color issue, has not a simple fix.
As you can see, the gradient used to bake the texture internally, has some green, red, but no blue or white, this because gradient map comes from max and that's why it goes wrong.
But there is good news, SDK developers want to add a Vertex color node in Octane Render.

Amazing, that'd be really brilliant.

Good news, thanks for bringing that forward Paride.
