can anybody tell me what’s the use of radiosoty mode??? when i’m in that mode, i clicked on “collect meshes” then pressed “go” then some “calculating” process took place. I just saw it in my friend but doesn’t really know what’s that for. I did’t see anything new happened when i pressed the render button. can anyone pls help me? It’s just been a couple of weeks since i started to use blender… thanks in advence!

If you look at the blender docs on the Blender website they go through radiocity fully.

Quick answe - create a mesh, turn up the emit value. Put it near another mesh. Select both and hit collect meshes. Hit go and watch the light effect the other mesh.

Ding, thankyou!
