Hello,
I would expect the following to work with vertex displacement. Please could someone confirm if a bug?

Basically I don't want displacement or very little near where water meets the edge. Using a dirt texture to mask where the water intersects with another object and a 128 grey value to for no displacement.

Mix texture
Amount = Dirt texture
First slot = 128 grey (no height)
Second slot = Displacement texture

Isn't the problem when masking something out with Octane in Comb Material, the Displacement will override the mask.

I have also tried this, having a displacement in your material, but soon as you comb it together with another material, the displacement is reset and you have to add it to the comb node and then it will override it all.

Dont know if I am making any sense.

Just saying, you cant mask a displacement, but a bump you can.

Personally, I think this is a bug, because this is vertex displacement and not texture displacement, vertex is not bound by the same restrictions as texture displacement, think chaos texture or tri-planar for example. When I put the same mix node used for displacement into the albedo (image above) you can see it is correct, grey is where it should be on the texture, so to me it makes no sense why this would not work in the vertex displacement node in my opinion

Hi tombyron,
Could you share the scene? I'm not sure if I understood correctly—are you trying to bring the displacement of the waves to zero when they meet the sand?

Yes he is, and he is using a dirt node to mask it.
