I’m not sure if it’s my end but I don’t know why opacity masks on Nanite objects such as landscape or planes never work, when I save or rebuild Nanite, it removes the opacity mask, I’m working with a really large landscape that’s tens of kilometers wide and wanted to add holes in landscape for things like tunnels, basements, or other things. So is it possible that it does work and it just something wrong at my end or it doesn’t work at all
opacity on a landscape? this is likely not supported. doesn’t make much sense either way. opacity messes with raster bins and nanites culling logic. mosdef why it’s not working on landscapes. i’m guessing tho. haven’t actually tried.
also… basements and tunnels? well… you’d have to explicitly model that with real geometry or construct it with some terrain meshes or whatever you build the basement from.
