Hello,

This has been and continues to be a thorny issue in my side. This technology is in its infancy, so I suppose we need to be a little understanding of that.

  1. With the POST PROCESS. You can create a softer effect from the lighting that can smooth (all) edges.

  2. You can increase the “Final Gather Quality” in the POST PROCESS.

  3. Check out information on Lumen and how it bounce-lights objects here:
