I make some mask to mask diffrence grass layer(use masknoise node), and i use copylayer sop to output.
I check mask layer is not overlay in cop
but when i bring hda in unreal to build landscape layershader, those grassmask(from masknoise)will overlay all the layer.
another question is, is plugain cant read float maskvalue like 0.6 or 0.2?
