Baking Light takes forever

Hey,

I'm pretty new in this thing. I just completed my first map and wanted to bake the light (I probably should have done it while doing it) but no it takes forever. It says something like 4 days when I stopped it and it never got more than 1%. Am I doing this wrong?

Thanks for your help!

Use the progressive GPU if you can, and also start with a lightmap resolution of say "1" and see how it goes from there.

 

Thank you! I try that! Any other performance Ideas? My map is the standard size and I have a MacBook Pro 13" from 2020 with 16gb, a 2 GHz Quad-Core Intel Core i5 and an Intel Iris Plus Graphics 1536 MB.

 

Hmm you can't use GPU then. Try even lower Resolution and make sure your Samples values are low.

 

Ok thanks! Is it possible, for final output to render the project on a different machine and import the light maps back into my laptop?

PS: You did Lost Echo? I loved that game!

 

It should be possible, yes (although, there were some issues with generate lightmap UVs generating different UVs on a Mac and different on Windows, not sure if that's still the case, but that might cause issues). If you have some versioning to sync between different machines it should "just work", otherwise you need the to manually copy the LightingData.asset and the .exr files.

Glad you enjoyed Lost Echo

 

Ok, this took around 30min to complete. So I should just set this number up bit by bit until it looks good and renders ok, right? And I read that I can disable realtime lightening, what I've done. Should I turn it back up now? Or just keep it deactivated since it will be deprecated?

 

Or you can have specific meshes look better by selecting them and changing the scale in lightmap value in the inspector, so you can have certain meshes use more or less space in the lightmap.

Disable the realtime lighting in the lighting settings, you're probably not using it anyway.

 

Ok thank you a lot! Now I have something to "play" with!

 

I played around a bit - now at light map resolution of 10 and everything worked fine except there are two objects rendered wrong in white... any idea what I could do?

 

Everything okay with the UVs of that house? Can't really tell what's wrong exactly.

 

I check the UV!

 

Make sure you have cleaned your GI cache.
Go to Preferences >> GI Cache >> Clean Cache.

Divide your scenes into blocks and bake lighting data separately by blocks
Switch the "Lighting Data" according to the block.

 

One of the best solution is to use Adaptive probe volume
