Light Baking Issues

Unity Engine
1

Hi guys,

first to make things clear, I would like to say that I am a total noob in Unity. I have loaded a small cloister scene into Unity and I am having the following issues when baking the light.

  1. Issue - Weird colouring of geometry after baking. See Picture 1.

  2. Issue - Some of the geometry that is in the shadows has incorrect light maps and appears very dark or completely black. See Picture 2.

  3. Issue - Unity says that there are overlapping UVs on almost all of the geometry, yet I have unwrapped all of it in 3ds Max. The Unrwap Editor in 3ds Max shows overlapping only on a few objects. The objects that are perfectly unwrapped in Max still have light baking issues.

You can see my Unity Lighting settings in Picture 3.
I hope you can help me, have a nice weekend.

Have you tried generating lightmap UVs in Unity?

Hi,

thanks for the reply. Yes, I tried that, but the result was also a little bit messy. It didnt resolve the problem and it looked like it isnt able to stich some ot geometry correctly after generating the lightmap.
I read in the unity docs that changing the lightmap resolution could help. So I am experimenting with that too and for now it seems to be bringing better results. It still isn`t perfect but there are definetly some improvements.
Will go on experimenting.

Hi,

so far the best solutions that I found was on the unity docs page

I increased the resolution of the entire lightmap from 10 to 20 texels and also increased the resolution of the problem-objects in the lightmap and it worked like a charm.
