Hi Luxcore users, For all of you, who are working intensively with lighting setups, I'd like to recommend a new way to get IES files.

Hi. Unfortunately, @B.Y.O.B. is left the development of BlendLuxCore for Blender as he hadn't got enough money for his hard work between development. So thats why we have no main developer now.

Thanks, I stripped out basically everything except an area light and a plane.
Luxcore v 2.4 shows a green plane.
Luxcore v 2.5 renders black image.

Thanks for any ideas...

The output to the console also doesn't show any errors. Is there a way to debug what is going on? Are ...
