Extra "default" light group.

[pciccone]

Hi.

When generating the following code (.lxo) I get an extra "default" light group in Lux. The group has no effect on the scene but it's confusing to have it. I can't seem to find a way of removing it. The mesh light is the only light in the scene:

Code: Select all

Thanks in advance.

Hi,

That's because a "default" light group is automatically added before the parsing starts in case a light doesn't specify a light group. That could obviously be enhanced.

So, if I understand this correctly, this is a Lux bahavior and there is nothing I can do to prevent it? Or is there?

Thanks in advance.

Hi,

Right now there's nothing you can do, but the current behaviour can be changed.
