How To Use A Texture Atlas in UE4?

Development Rendering
1

I use texture atlassing in Blender all the time, but I can’t for the life of me figure out how to do this within UE4 materials since i don’t seem to have control over how my UVs line up over my texture. Is there something I’m missing? Is there a way to control UV to texture placement? The closest thing I see available to manipulate textures is the texture coords node, and that isn’t going to cut it.

Thanks!

Manipulating the Tex Coords is the only way write now, there used to be an atlas texture format but it’s gone for UE4 I’m afraid, no official word if/when it’ll make a return!

As of 4.6 however you can sample 128 unique textures, so there’ll be little need for them after that!
