Title: Global illumination problem on Rayswitch Material // URGENT
Post by: fraymond3d on 2017-04-07, 21:23:52

Hi everyone,

I'am posting here something that I've noticed quite long time ago and never get rid of it. I use a Rayswitch material for background and just keep the global illumination slot empty to dont affect my image. At this stage, it create a bad shadow shape on the floor (see image). Iam Using HDRI Lighting (PGskies_0907)... And same if I use a corona sun.

See images here:

Anybody already had this kind of problem?
Thanks in advance!

Hi, I had this problem with textures from CG textures, the wood textures to use with floorgenerator. Don't know why though. Also some times happened the same when using color correction node. Check with a different texture if you get the same result or if you are using a cc node.
