I’ve been toying with the Generate Unique Uv’s tool to generate Lightmaps UVs and have not been able to have usable results.
Long shadows on walls bend;
Shadows are improperly placed;
Artifacts appear even where there shouldn’t be any shadow;
I tried a lot of parameters and options to no avail, it just looks wrong all the time, sometime it’s less visible but it isn’t as perfect as in Unity.
We come from Unity3D and their automatic Lightmap UVs are just working the way it should, no tweaking required. In rare occasions there’s some light bleeding but that’s all that can happen and when it does, and you don’t want to UV manually you can still increase the resolution.
I understand why you recommend doing it manually but to be honest Unity does a great job automatically, 99% of unity users are using it, the gain in time is substantial so why couldn’t Unreal engine do it?
Are there any plans to improve it? Is there a trick that makes it 100% effective? Perhaps a 3rd party tool that does this instantly on a mesh?
