How to use Greyscale Vertex to mix Displacement?
Posted: Fri Mar 24, 2023 3:13 am
I have a vertex weight map to isolate two mesh parts to apply a different image-driven vertex displacement to each part using only one UV. In Modo native, I simply assigned a part tag to each and dropped the texture maps into a group for each that adds to the same material group applied to each. But in Octane, everything has to be 1,000% more work. So I made a weight map and plugged this into the amount on a mix node and this into a vertex displacement node. I also tried this with the mix vertex displacement node. Both options result in a mix of both displacement maps on both mesh parts. If I solo the weight map, it looks correct, and if I plug the result into diffuse, it works correctly. I wasted ages trying every combination I could think of with this and trawling the inter webs to no avail.
Am I hooking this up incorrectly, or does this simply not work?
Ultimately, I made a quick texture map to replace the weight map, which works correctly.
