"nan" means "not a number".
So something went very wrong.
Can you upload a scene that can be used to reproduce the problem?

Hi

The scene is too big to upload on our 2MB broadband .(400MB)

I will try and recreate in a smaller scene or strip out as much as possible .

Might not be able to do this for a few hours, sorry.


Thanks

Maybe it is enough to remove the most high poly objects and all image textures.

Ah!

I have a large amount of small lights in the scene, which has been working fine. But I turned of the only non-mesh light (the sun) and that is what caused the problem.

Fixed.

Thank you

It would still be good to know if this NaN value was to be expected (e.g. because the brightness of the sun was turned up and it exceeded the maximum possible value of the float data type) or if was a bug in LuxCore and could have been avoided.
But I guess it was the former. How was the sun configured? Did you turn up the gain?

I'm trying to reproduce this issue, but to no avail.

When the Sun was switched off, the 'nan' occurred. When I turned the Sun back on (value .0001 with Sky on and linked to it) I then got a recommended brightness of .1

Unfortunately, turning the Sun off again isn't producing the 'nan' value.

I've attached the Statistics with Sun Off which I hope is of some help.

What's the maximum file size to upload? I'm at 19.3 mb but it's still too large
Thanks

10 MiB.
You could use an external hoster like dropbox, google drive, sendspace etc.
