Lightmapping stops working with the message "Lightmapped renderer has no UV mesh!"

Unity Engine
1

I’ve had this happen multiple times, both with custom lightmap UVs, and with Unity’s own lightmap UV generation.
All I get is two errors in the console with the message:

“Lightmapped renderer has no UV mesh!”

Anyone know what gives? :frowning:

I see that error sometimes, too, and don’t how to work around it. It doesn’t ping the offending object or offer you ANY help in figuring out which “lightmapped renderer” it is refering to. If it would just tell us what object it is talking about, we could try to find the problem…

I had that problem too and what fixed it for me was to tick the ‘Generate Lightmap UVs’ for all the models I am using. thankfully I could mass-select. I am guessing that in my case, one or more of the models had an issue when it was imported and Unity 5 seems a little less tolerant of those than 4?

Hey Acegikmo,
Seems like we don’t have a solid repro case for this issue. Could you please submit a bug report (Help > Report a Bug) with a repro project? Please post the case number here when you do.
