Square pattern on landscape painting

Hello,

I would like to get some help here on creating materials to paint onto landscape. I created this terrain and just played around with the materials creation process while I am learning how to use UE4. I tried to use some material textures from the KiteDemo package to create some materials to paint onto this terrain. However, it appeared that the materials are painted in square pattern (especially the cliff and mountain rock textures) instead of a smooth continuous layer of material.

As for this image, I followed the instruction from the UE4 doc. on the “creating materials for landscape” section and used the material texture from the example content package. It appeared that the materials are painted smoothly and continuously on this terrain.

I wonder what happened to the material texture in the first image. Is it because the texture files in the KiteDemo package have been formatted differently? Thanks a lot for your help!

The landscape is made out of a series of smaller square meshes which makes it a little more efficient, what you are seeing here is the borders of each sub square. You just need to rebuild your lighting because each time you sculpt your landscape your are changing the geometry which renders the baked lighting information irrelevant.

Thank you, Night Watcher. I will try that to see what I will get.

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!
