Hello,

I'm looking for a way to blend displacement textures, similar to this example: https://vimeo.com/113085136

Basically, I have 2 PBR shaders, each with their own displacement maps. I want to use a mix material to blend the two together, driven by a black and white image texture to define which texture goes where. I can blend the two materials, (Which seems to blend diffuse, spec, gloss maps etc) but not the two different displacement maps. I can't seem to use a Octane Mix Texture material to blend the two displacement textures and plug it into the displacement slot in the mix material - it doesn't displace at all.

How do i go about doing this?

Thanks!

I think the only choice you have is to precalculate the blending between the 2 displacement texture in an image sequence,
because of the Octane displacement limitations:
- displacement only accept image texture as input
- and when you blend materials, only the displacement of the mix material node is used

Thanks Calus. That's a real shame that octane doesn't support mixing textures inside Maya. It makes blending environment textures (grass / rocks / sand etc) very difficult within maya.

The displacement limitation is in Octane core, the Maya plugin can't do much about this.
But I think some great improvements for displacement are on the Octane3 development road-map.
Also OSL in Octane 3.1 will open the door eventually to unlimited improvement/feature for textures in the Maya plugin.
