I'm trying to use texture painting with UV maps (both of which I am new to), and when I go into texture paint for my model, I can't paint it. I have UV-unwrapped the model when in edit mode with smart unwrap, set the texture node as active in the node editor, and selected my image file. Is there anything else I need to do?
I figured it out. Landscape meshes are created with inverted normals. I inverted the normals back on the left sidebar. Afterward I was free to paint.
