Terrain glitch
Loaded up this lot to continue building and the terrain had this pattern
I’ve added the brown terrain paint to show it more clearly but also, it shows through the new paint. What’s going on here then? The whole lot is like this
Edit It seems this is a problem caused by big textures used in terrain paints
