Does not seem to work with Blender 2.93+

'Build Lightmaps' doesn't actually bake lightmaps anymore after updating to Blender 2.93.

Hi, that sounds strange since it works just fine on my end with that Blender version. If you toggle the console, do you get any error messages? - Oh, btw are you using the OIDN denoiser by any chance?

[kitaedesigns]

Ah ok I checked the log and OpenCV/Filtering enabled seemed to be the problem. I will try reinstalling OpenCV as Admin with this version of blender and see if I can get Filtering to work again.

[Naxela]

Hmm, I just noticed that the filtering doesn't give alerts when something is wrong anymore. I take it you didn't get some kind of info alert notice? - I'll look into it, thanks for the bug report! 👍

[kitaedesigns]

I didn't get any alert notice, the TLM_Overlay would appear but then nothing would happen, usually blender freezes as I bake in foreground mode, and that didn't happen and it was only when I checked the console log did I see that something was up with the OpenCV and Filtering.

[Naxela]

That definitely sounds like a bug. I'll look into redoing the error messaging system in the future to be more noticeable, or at least not require the console to be constantly open.

Tried reinstalling OpenCV and got a successful message in Console Log, however when I restart Blender it says OpenCV is not installed.

Hmm it seems like some strange has been going on in the recent versions. I think it's the same problem that Olliebarbs got, and it seems like he managed to solve it by copying the cv2 folders ino the local python site packages folder: https://github.com/Naxela/The_Lightmapper/issues/122#issuecomment-914134536

Could you test if this works for you?

[kitaedesigns]

Ok I'll try that and report back.

I tried copying and pasting the OpenCV and CV2 folders into the local python packages folder of Blender 2.93 and it seemed to do the trick.

[Naxela]

Thanks for testing it out. I'll try to see if I can make some kind of workaround that solves this issue
