I'm currently using Blender 2.8
In the file i'm working on, i unwrapped a mesh (Smart UV Project) -> Add base color in the "Texture Slot", but then i am unable to paint over it.
Therefore, i tried creating a sphere in the same file and try texture painting it, it doesn't work as well.
So i created a new file and try that again, it works. Can anyone explain why Texture painting works fine in other files but not this particular one? I am new to Blender so any help from you guys is very much appreciated!!
