Wrote materials, meant layers.
I have the plugin, but I have actually never installed it, no idea of what it does really.
but at a base level you need the terrain to return anything but False within the pysmat for it to work…
Changing the physmat should cause some shaders to recompile depending on how it is done - changing it in the material itself does cause the whole material to recompile, obviously…
And the plugin was perfectly functional, they just forgot to hook something up at Epic in the latest build. All landscape physmats seem to return False.
