Hi,
I just tested on my end and it doesn’t seem to quite work. I’m using an RVT terrain so I’m not sure if this has something to do with it.
Maybe I am missing something? I looked around for checkboxes that could be related to activate this in the material itself or the Landscape actor, and nothing.
Chaos solver is ON, I’m on 4.26.2
EDIT: Nevermind that, the mask just happens to extends much farther than I expected. I was able to get it working from a Render Target without “normalize” on my end.
EDIT2: Something pretty important I noticed too, the changes only seem to actually take effect after I re-assign the default Physical Material to the landscape. Otherwise, any changes I made don’t actually update.
