Unsolved Road Textures Z-Fighting

I have set up a couple of textures for some roads on my new map and they seem to be Z-Fighting (heights are the same causing the textures to flicker when moving around them). I have changed the renderPriority, zBias and decalBias. Anyone got a fix?

 

This is often an issue for me. I might be wrong, but I think there was an issue where it wasn't saving the render priority properly.

Try looking in the .json file and finding the priority setting and modifying that there. May work.

Hopefully others here will have an answer.

Out of interest, is it a large maps you're working on?

 

Thanks, the map is quite large (5x5 miles) and there are a full list of features I don't believe have been done before too

 

Try to activate the Z-Write flag in the materials. Hope this may help

 

How do you do that? It's been a while for me since I messed with materials. In fact it's been a while since I did any map making at all.

Thanks in advance.

 

material editor>advanced - all layers

 

Thanks!

 

I've tried this already, every road texture has "Z-Write" activated and adjusted, still no effect

 

Have you tried lerp?

 

I have tried changing the "Alpha Blend Mode" to "LerpAlpha" and it seems to have partially fixed it, thanks
