Lightmix with batch render not working - render elements are black

[duzami]

Hello,
I've put different lights to different layers, set up lightmix by layers, and everything worked fine in rendering, untill I made batch render, saving to .cxr. For some reason the only working light element is environment, and all other lights are in "rest - unassigned" which makes the lightmix useless.. All light elements that I wanted to have, rendered out black. Am I doin'g something wrong? Any ideas?

Which version of Corona, and Max, and is there a difference if you don't use batch rendering?

Hi,

Please always tell the version of Corona and 3ds Max you are using (and in this case also the CoronaImageBatch version), it will help us to have all the needed information to come up with suggestions.

If you are using the image batch coming with Corona 11 (CoronaImageBatch V11), please try using CoronaImageBatchV5.

It will be slower but it will probably process all files correctly.
There is a known report for CoronaImageBatch V11 for batch processing many files sometimes not processing all of them.

(Report ID=CMAX-834)

Hi,
I'm using max 2024 and corona 12, I'm  not sure how to check corona image batch version. It turned out that if I don't use batch render the problem persist - although before (before I've set up batch rendering) a single render worked fine. I've deleted lightmix and set up a new one andit worked.. but it would be nice to know why that happened, because my client was unhasppy as he received his renders later than expected... is there something i can do to avoid this problem in the future?
