I have a big problem. I have been spending 2 days to just to bake my lightmaps. I have been trying all over again for like 30 times now and it takes approx. 1,5 hrs to do so per baking process. I have searched for the solution everywhere, i tried various things. But no matter what I do, it seems to be futile. When I bake my lightmaps; two things happen mostly;
1- Everywhere not getting any directlight becomes completely black, or
2- My trees’, rocks’ and some other meshes’ shadows go completely black.
I have tried several solutions, including using lightprobes, changing my lightmapping settings (even if how I was frustrated), raising indirect light intensity and so on. I use ambient occlusion, too.
Also, I have done the lightmapping tutorial provided in docs. Even if it diminished my baking timedramatically, I still have problems.
These are my baking settings;
This is what I am talking about;
And these are my lightprobes;
How can I solve this problem? I am fed up with lightning and stuff and I start to hate it. Please help me out.
Is there a reason why you have both realtime and baked GI enabled? Enabling both will increase your bake times significantly, in addition to incurring a realtime processing cost. I’d recommend that you’d decide whether the lighting in your scene is going to be static or dynamic and the stick with that.
Also, make sure to inspect your lightmaps using Baked Lightmap view. Check whether you have objects with high lightmap texel density, and make adjustments per object basis.
If your scene is very large, it would also make sense to not lightmap distant objects as this will increase the size of the light grid.
If you have any LODs in your scene, make sure that the lower LOD levels are not lightmapped, as this again will increase baking times.
I have been experiencing very similar issues. I don’t seem to receive ambient lighting whatsoever in my lightmap bakes, so all shadows are extremely dark, especially in covered areas. Baked GI helps brighten things a bit, but not nearly enough.
Pretty much lightmapping in Unity is a complete mess at the moment.
