Anyone gotten this feature to work? I have a simple test landscape, with two landscape layers, each with their own physical material, Rocks and Gravel. Doing a line trace down from my player returns the correct physical materials for both of those as I walk around, most of the time.
I added a Landscape Physical Material Output node to the material, outputting a physical material called Puddle. The result is unpredictable.
Sometimes the traces never return puddle at all. Sometimes they only return puddle across the entire material. I have yet to get the output to actually correctly return the puddle physmat in the spots I’m specifying with my mask.
