In my project I have a layer which adds a hexagonal white, nonmetalic patten, it is a fill layer with a black mask with a tile generator.
Suddenly, my model looked like my first image, I wasn't able to figure out why. Repeatedly my current material set went totally matte black then crashed. I restarted my pc and found the source to be 2 normal map fill layers and this grip color layers.
The Normal maps were producing similar effects to the images of the strange checkered pattern, even when hidden. I deleted those and then found that I could toggle the effect on and off with my grip layer.
I turned it on and off and got these screenshots. I save as'd the project to save the problem.
To fix it I copied the grip height layer as it is just a modified version of the same layer with the intention of undoing the changes from color to height with a bevel. But strangely, after copying the layer and enableing color, the previously broken layer started behaving perfectly normally.
If anyone knows why this happened that would be great to know. I included a version of the broken project. Before I fixed it but when I reload that save its fixed already.
