I never had a problem befor. I just made a nice landscape with caves and underground rivers.
But. all the textures are bad.
They are not textures, but just colors. See photo
From the image you supplied, it looks like there is issue with UV mapping or vertex count per face of cube. Make sure your texture is set for ‘Clamp’ or ‘Repeat’ as needed. Check tiling values in shader inspector.
What you’re seeing is the texture zoomed in very close, can’t tell you exactly why though. Unity’s cube is basically a quad on all six faces, if your cube is not, then you need to properly UV map your mesh. Are you using a standard shader?
Yes, I been through all that. I just download the new unity and installed that computer. On my other computer I have a older verison. It works fine with that unity. Yes I am using the standard shader. No problem I will keep working on it untillI find what is wrong.
