It doesn’t matter how I unwrap the lightmaps (even on automatic - the one that separates each face), it always has some kind of weird artifact like the one on the upper part of the door or visibly incorrect shadows/lights. I even tried to place it in a blank scene with default lights, no luck.
I’ve already read a great amount of tutorials and tips on how to proceed on this, but nothing seems to help it.
What can I possibly be doing wrong?
what happens if you increase the lightmap resolution and then rebuild lighting?
automated UV systems hardly ever give perfect results.
a few things about your lightmap: I notice you would have a much cleaner lightmap UV if your model was optimized a bit better(check [this thread](Need help with unwraping :( - Audio - Epic Developer Community Forums for more info(it would also be easier to unwrap it)), you don’t need to separate the UV into that many UV islands, and you might want to straighten up the skewed parts of your UV as it can give skewed shadows.
Weirdly enough, I re-exported the mesh as an .obj from Blender and the problem is gone (no need to reunwrap, but I do get your point… the map was not optimized at all because it must be the 99th time I did it from scratch and I was becoming a little unpatient hehehe).
It seems that this is a problem with FBX export in Blender or some missing setting… still confused about it :S
Unfortunately, I tried the same with other problematic objects, like the one below (which has a nice uv layout) but still get weird results. This time they are more traceable at least, since they lie in the uv seams:
What is driving me crazy is that it has almost the same uv configuration of other similar objects in sample scenes and they look perfect (like the couch in the RealisticRendering scene from the “Learn” scenes):
ue4 that is! that must be the reason why I’m having such a hard time finding info on the internet
Ok, so I imported this premade couch on my scene and… surprise! Same problem.
So this is probably a problem with my light setup or some setting I don’t know about yet.
Any suggestions?
