I am having this issue with painting soil texture over grass. This was working fine previously, in fact my material has 7 layers that all painted nicely together. This issue started cropping up recently and I am not sure what I changed to cause it.
It’s fine where it’s blended but areas that are fully soil show these blocky textures. But if I pan and look from another direction it looks normal. If I remove the directional light from the scene it looks normal.
To narrow it down I made a whole new landscape material and just blended two layers, the grass function and the soil function. Made a new level, new landscape and applied the material. The same problem happens!
Am I missing something easy? How can I fix the problem?
