I'm new to Blender and have tried to make myself a large cave model. After I've finished it, I tried texture painting it and am successfully able to, but it seems the quality of the texture being painted to the mesh (im using Stencil) is a bit blurry. I tried the same image on a smaller object and sure enough, it painted very well.
Based on my research, it has to do with how my UV is unwrapped. If I unwrapped a small object, it is unwrapped looking large on the UV map (sorry if wrong terminology) and paints in high quality. The problem is for large objects, when you unwrap them, the islands are forced to be small (even with seams) in the UV map or else they wouldn't all fit in the UV Map.
What can I do about this? Is it possible to have multiple UV maps so I can put each island on their own UV map? Or am I doing it wrong and there is the right way to do it?
