Hello there, Im a beginer and Ive created this rock in blender where I did the modeling, uv mapping, texture, normals and baked. Actually I just followed a yt tutorial step by step… Also I did the export/import (following another tutorial) process and this is how it looks in Unreal Engine.
Blender creates ugly normal maps but in your case I think there is another issue. Normal maps, need to be set as normal map in Unreal Engine. The easiest solution for this is, to put _n or _normal to end of the file like: rock_n . png . if you import this file it will be set correctly in Unreal Engine.
