Casting shadows with the new 2.28c Radio render

I can set up a room with some emitting planes, and it renders fine (no lamps needed).

The only thing I’m missing are the shadows. I must be missing something fundamental.

Any tips?


remember that the radio calculation uses vertex colors. the mesh on which the shadow casts on has to be [heavily] subdivided.

After all these years … now i got it. :stuck_out_tongue:

It works fine, thank you!
