A rectangular window is easy, just drop the window mesh and add a peace of basic geometry generated by UE and turn it to subtractive. But say I have a window in a shape of a heart… I would have a second peace of heart shaped geometry a bit smaller than the frame of the window itself and that shape would be turned to subtractive mode. Thing is I don’t know if or how to turn a peace of imported geometry to subtractive mode.
Would;d it have to be a mesh or perhaps an option in materials
Thank you,
