SD Material Shading Error

acealmighty13 · Jan 2017

I'm picking up these triangles on this SD material I created and the straight lines look great yet these pop up in the UE4 editor. I went back to the file and found the lines are jagged. I'm trying to fix it with a Blur node and Levels to even it up but it isn't going very well. This mask is a zoomed in image of a 4x4 tile through the Tile Generator node. I'm assuming this is the problem but could be wrong. The material looks great in the SD 3D view.

Two things can you post a screenshot of your material in ue4 and also have you tried baking lights to see if that fixes it? Could possibly be your light maps, do you have them set to auto gen in ue4?

I found out on the Allegorithmic forums it's a DXT compression issue. And just yesterday the company released an update to their UE4 plugin that should fix this problem by using BC compression.
