Hey maxwellers, rendering a spiral staircase for a job, using 2 emitter planes, anyone know what the streaks are from on the left hand side, or know how to get rid of them?
Cheers
Brett

Jpg compression Is it like this right out of maxwell?
If not save in a different format and see if still happens!
Edit:
I take it you do mean the banding on the background?

I always save out renders to 32 bit hdr format. Then you have the most color depth to work with in Photoshop. When you save out as png, it is 8 bit.
