If I add a layer, in this case the second "dirt" one, to that square area, the entire area immediately looks like a bad trip. If I remove the dirt layer (subtract it from the square area until there's no dirt left there), it disappears. There are several of these, in different locations, that screw up all my layers except for the base layer.

WTF?!

What is this and how do I get rid of it? I've been able to work around them so far, but I won't be able to do that for long.

Someone correct me if I'm wrong but I think it has something to do with the complexity/amount of the materials you are using in your terrain materials.

To fix it I think you have to use materials that don't use as many textures or cut down on how many terrain materials you are using for a single terrain.

I've only had this same problem once so my memory might be off but I think that's how I got around it.

This started happening only after the third layer! I need those three layers!

*sigh...*

I may be able to work around them. If I can't- any good rock or dirt materials that only use a couple textures?

I haven't worked with terrain for a while, but it should be a problem with the amount of texture samples you have combined in a terrain actor. See this page for more info.

Then make copies of those three materials used, and then simplify those. Get rid of expressions you dont need. You should be able to use at least 4 or 5 layers if the materials are simply enough.

To be specific and if I remember correctly, terrain can display any info going to the specular channel of the material, so that's just wasted resources and a texture sample.
