Solved Decal road problems

Okay, for the last two hours I have been trying to stop decal roads from flickering with no results. I can't find a way to place decal roads on top of each other without flickering, but I know that it is possible.
Example: This intersection in Utah has multiple decal roads on top of each other and they don't flicker.

I've adjusted the render priority, decalBias and zBias settings and copied the decal road settings from other maps. I've even cleared the cache if it was a texture problem but it didn't help.

Any help would be appreciated

Check the render priority.

 

I have seen that post and changing the render priority does nothing.

 

Is the terrain flat in that area?

 

Not completely flat but still very flat and it's also tilted a bit.

 

The non-flat terrain will be the issue.

 

Now I realized why it did that. There was a problem with the road's normal map.
