Re: checkered maps appeared

The problem is that you have overlapping surfaces. Separate a little bit the blocks, just a very small distance.

Re: checkered maps appeared

what are you trying to achieve?

Re: checkered maps appeared

The image is kind of noisy and dark, but I like the effect of the ice material.

Best
