WebNow, I'd like to have shadow mapped point lights as well. The things is, though, I'd like them to be as fast as possible. I'm not that interested in the quality - I can get away with really small shadow maps (256x256 or even 128x128), and I don't need soft shadows … WebIf we use a 8K by 8K shadow map atlas and the minimal resolution of each shadowmap is be 64 by 64, then we can fit 16 384 unique low resolution shadowmaps into the atlas, which is enough for around 2730 point lights. So in practise you can store shadows for dozens or low hundreds of point lights at various resolutions. WebThe big/important lights (LOD!), where you are going to notice the shadowing more, could use shadow maps. Again, not that much into this stuff and don't know too much about graphics. (Also, you'll probably already know about it, but (tiled) deffered rendering is great for huge ammounts of light sources) 2 level 2 -manabreak Op · 7y cinnabar bracelet chinese
