Night Watcher,
I did as you mentioned and rebuilt my light in the scene. However, that did not solve the issue. As you can see in this picture, the material textures still appeared as a square pattern after being painted onto the landscape.
In #1 highlighted in the picture, the “Mountain Rock” texture is painted in a square shape pattern in a closer look. In a more distant look, it looks like the #6 highlighted area. I don’t want the greenish borders around the texture. I want it to be a smooth, continuous rock texture.
In #2 highlighted is the “Cliff” texture and it also appeared to be in a square shape pattern. I also don’t want the brownish borders around the texture.
What I want is that I want to paint these textures on the landscape to be more like the highlight #3, 4, and 5 even though the “Ground Grass” texture appeared to be smooth in #4 but with square pattern shape in #7. But #7 is in a farther out view so that does not really bother me.
Any other suggestions or advice that could help me out? Thanks!
