Light Cache with LightMix undersampling issue is still there

[labulle]

There is a weird behavior with Light Cache display when using LightMix. I guess the change mentionned in the Update 1 changelog has an issue:

• LightMix during Light Cache building and progressive undersampling; - no more black VFB during LC when you have LM active

I have found that it depends on the number of lights grouped by LM. If it exceeds the 64 limit, the Light Cache shows the weird dot refinement, if not (by masking some lights or changing the grouping type) it undersamples just fine.
Also, the 64 limit warning seems to not always appear in the log.

Thanks for the pointer, will see if it can be fixed. In general if the limit is crossed odd things might happen. I'm thinking of extending this to 128.

Best regards,
