I have one issue with Cycles. Currently I have rendered one image with a plane and shadeless material.
I am using 1 render sample since i don’t wont to use GI and I want to have short render time. How can I soften the edges of the rendered plane ? I tried with Filter, but it seems like its not working for this example. Before in Blender Internal this issue was an easy fix Eevee is not an option.
Your plane is too bright, super bright objects eat AA. Don’t go over 1.0 in value if you don’t want weird stuff to happen, also as @zeauro said you need more than 1 sample for AA 4-8 should be enough for a quick job, 16+ for high quality
if you don’t want GI why not turn the bounces down to 0?
