Ah, my mistake for not mentioning. I’m using the ‘Landscape_Intersection_Blend’ set to true here here:
and yeah, in case I don’t use that, you’re right and it’s using the Vertex Color as expected from looking at the material.
This is the material function used: (I don’t really know if this is the correct way to share blueprints, but here it is in pictures from the blueprint editor)
But your information did give me an idea as to what caused this and I figured it out. So to any future people arriving at this thread:
You can see the Texture Sample that just appears as gray in the middle? That’s infact this heightmap:
Combining that heightmap with the 4 values taken from Parameter collection, that’s effectively the mask for the entire landscape in a nice pretty range between 0 and 255. All I had to do was update the Corner1 and Corner2 values to the min and size of my own level and then update the heightmap there to one that matches my own landscape. After I did that and rebuilt the shader, everything works perfectly.
So thanks a lot for your help .
