[Solved] Lightmapping problem with modular assets

Unity Engine

Hello !

I’ve spent the past few days looking for a solution to a very annoying lightmapping issue, and I didn’t get any convincing answer.

So here’s the problem :

Lightmap settings

418×875 128 KB

As you can see the irradiance map is kinda broken, same thing happen with baking.
I’ve tested the default settings, increasing atlas size, resolutions of GI and Bake, check / uncheck compression, check / uncheck the generate lightmaps option in model inspector.

I also tried to let unity take care of normals & tangents when importing models, which only breaks normals since i’m using manually edited vertex normals.

I did read on forums, that this issue is recurrent since Unity 5.xx is out, but it’s been a long time now, so if anyone got a solution for these…

Thanks !

Try a test with progressive light mapper. If your problem still happens, it’s from your settings.

Well, switching to beta and using progressive lightmapper does solve the problem, but still in beta so a bit buggy.
Thanks for the tip !

Looking forward for the release.

PL is not beta. It’s now completed and called experimental because all features is not implemented yet.
You can use beta10 that has transparented baking feature .Now i think it’s a complete ready to use solution for your games. Just wait for unity 5.6 final version. Unity 5.6 is beta and not PL…

It can bake GI like to CG renderers. I have tested in a lot of scenes and it works fine. Just create a new lightmap parameters settings file and set Backface Tolerance to lower value (0.4 or lower). I found a simple problem in default settings in some models.
