Won’t I have low quality shadows in this case?
I’ve just tried that, and in this case the quality of shadows on this big wall modeled as unique static mesh is very bad. See attached screenshot for example. The SM floor on the left has resolution of 128 and the BSP floor on the right has resolution of 8, everything else is equal. See how shadows projected on the big SM are bad while shadows on small SMs and big BSP are good.
Is there something I can do to improve quality of shadows on big SM? I noticed that in Blueprint Office example the shadows on the same mesh becomes much better when you are closer. How is this achieved?
