LuxCoreRender Forums

Hi,

I have one scene that rendered well in v2.4. But in v2.5 the combined view layer is all black.
The irradiance layer is o.k.
There is no error message in the luxcore panel in blender (v 2.83.5).
The output to the console also doesn't show any errors.

Is there a way to debug what is going on?
Are certain nodes not comptible?

Thanks for any hint on what I could try...

It is hard to say without having the scene: try to erase as much as possible in the scene (whiteout removing the problem) and post the .blend.

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 scene has some wired setting for the default light group, I'm not sure where they are coming from, they may be the result of some change and new support for light groups added to BlendLuxCore in v2.5.

As work around, just create a new light group (under Scene properties tab, LuxCore light groups panel) than assign the light source to the new light group (select the light source, under Object data properties, select the new light group).

This will reset the light group data and the scene will render as in v2.4.

Thanks a lot Dade, that really helped!

I haven't been using light groups until now - but I will definitely look into this feature...
