Warning: Invalid lightmap samples

[cristoforo]

What does this message mean? This refers to the light cache? My settings are: subdivs 1000, sample size 0.01 scale - screen, # passes 4. The scene renders, I just suddenly received this message. Will it cause me problems?

[Candelero]

This usually means that one or more rays, which have been traced during the GI calculation, have reached out of range numbers like:

#1 intensity is more than 100%
#2 overbrighted areas
#3 problems with UV coordinates
#4 buggy materials (usually with wrong setups of glass-type mtls )
etc.

Lots of time this warning doesn't show any visual artifacts, though there is a problem somewhere.

Best regards,
