Slope gradient and deformed Geometry

Unread postby Ackiparait » Fri May 08, 2020 4:08 pm

Hey guys, shading question here, I have a polygrid as a base mesh for my terrain, I add a displacement deformer to that grid with an height map (here just a basic height map from world machine).

So I have my basic terrain shape, all is fine, but then I start addind displacement, using a gradient slope as a mask for blending shaders and textures, even to scatter, works fine but I wonder if there is a way to get the slope resulting from only the deformed grid result, and not the deformed grid + the displacement result.

I noticed this amazing slope gradient had different options (object / world / shading), but I can't find the best way to get what I want.

Thx you guys

The slope is evaluated on the final geometry. The only way is to bake the slope into a texture before applying the displacement shader.
