You guys have been awesome with help so here is another one that stumps me. Most of what I produce is size based related. I create massive sets to make people small. I am having no issues with character sizing but when it comes to  rooms and scenes its not working as well. With Reality lux i can collect original texture size and have no issues as in render 1. In render 2 which is produced in iray I have all kinds of artifacts. I am using 2048 by 4096 as suggested by Cickle in her vid should I be stting them different or is this a limitation or iray?

    In Render Settings > Advanced, try raising the thresholds for Texture Compression.

    If you are using the Ground Plane in Environment then try changing the resolution.

    Have you tried changing the horizontal tiling for the shaders? Isn't there a tiling shader in the free Iray shaders beside the Ubershader? I have them and didn't buy them. Applying one of them automatically tiles the shader to differnt amounts.

    Not that I can see. I did the tiling it works but there is still alot of artifacts. Lux is still slow comapred to iray

    I know this is a bit late, but I've only recently had this problem.  Bobvan,  just out of curiosity.  Is that guy in the attachment Matt Helm?
