As you can see on the screenshot, I’m trying to blend rocks on grass using layer height blend.
I tryied using “height blend” type on both grass and rock layers, “height blend” for rocks and “weight blend” or “alpha blend” for grass. I also have some maths to increase and offset the heightmap contrast but as you can see, some rocks still looks to be under the grass, even while painting rock layer with a tool strengh of 1 and a falloff of 0.
It looks like where both layers blends, height values of both layers blends too, so even if the height value of the rock is 1 (white on the heightmap) and the height value of the grass is 0, the height value result of the blending is 0.5, which means showing 50% of each material
Is there something I can do to “clamp” the height blend so the rocks will always appear without grass blended where the layer weight is 1 and the heightmap is 1 (white)?
