C4D Terrain mask effect not supported?

[Studio21]

Hi,

So ive been messing around with the C4D terrain mask in octane, trying to mask out between 2 textures based on GEO slope angle...it doesnt seem to work as expected. any solution?

Thx,

After watching the IBC2017 vids I want to try this too but haven't gotten around to it. Surely there would be some way to bake the texture out to define areas of snow / rock or similar and then use that to define the location of the different octane materials?

Would love to hear your thoughts or results.

Yeah, baking the texture from the texture tag as a last resort does sort of work...but its really not the desirable way. was hoping to keep the process a little more procedural. Ahmet, anything can be done?

Hi,
you need to use the Falloff node, but you need to change the mode to Normal vs Vector 90deg:

Hi,
It's working as expected for Octane plugin. Please read my following explanation.
When you use C4D shader you should understand how they can work. There's not any possibility to directly run these shaders in GPU. So they are rendered to bitmaps and used as an image in object uv space(u=0...1, v=0....1). So you should not expect a proper results if these shaders are using world coordinate system or camera_normal/surface_normals. This is the reason why you cannot get any results as you expected. I hope this explanation is clear.

Beppe and Ahmet, ty for ur answers guys.
