UE4 - How should I apply my material height map in UE4?

Soldeus

Hi, I did a quick brick texture to try out the importing process in UE4, and everything went smooth with 1-click with the Substance Plugin, but I've yet to find a solution to how or where should I apply my height map, as It wasn't automatically applied to the .mat.

Is the Bump Offset node the best(or only) solution I have to mimic the results I get in Substance Designer?

Generally you'd use your height maps in either a Bump Offset node or you can use Parallax Occlusion which I believe will give you the most similar result compared to SD ( https://wiki.unrealengine.com/Parallax_Occlusion_Mapping ).
Either way just don't forget that using methods like this will impact performance, so in many cases you you don't need a height map.
You could also use your height map as a way to blend in i.e. sand into your bricks or so.

Thanks for the answer! That's how I actually did it at the end. Managed to setup a Vertex Color + Heightmap blending and also added some Bump Offset, couldn't make a POM shader combined with a height map + vertex blend so this should do the trick for now!.

Another use would be in a tessellation shader.

Just learnt that way yesterday, gotta try it on my next environment!. (This one is for an art test, and I can't go over a triangle limit, so no tesselation allowed!)

Thank you both for the help!!!
