All of this (shadow catcher and transparent background) will be in the next alpha release. Tip: When you go to the release page on github: https://github.com/LuxCoreRender/BlendLuxCore/releases And click on "58 commits since this release", you'll see what we added since the last release: h...

(including the Python version required by Blender v2.8). We might want to wait with that, I will wait for 2.8 to get more stable before I start making the new addon ready for it. At the moment from what I read 2.8 is unusable for anything but experimental tests (a bit like BlendLuxCore), half of th...

It is perfectly ok to use 0 W and 0 efficacy. In such a case the brighness is only controlled by the gain.
It's a bit counter-intuitive, I know.
Only if you set the gain to 0 you get a "switched-off lightsource".

It is already implemented, will be in the next release.

I really need to add support for the default world volume.

P.S. going to check volumes absorption code, I have the strange feeling it may be something wrong. Note that BlendLuxCore is implicitly creating a colordepth texture for the "Absorption" socket: https://github.com/LuxCoreRender/BlendLuxCore/blob/master/nodes/__init__.py#L126 Maybe you mea...

My stance on it is: Material preview does not have a high priority for me. If someone else needs it urgently or sees the matter different, he can go ahead and implement it and I'll answer questions if there are any. If noone else does it, I'll probably get around to it in a few weeks. I see your poi...

I tried to replace your meshlights with lasers but something is really going wrong.
Will have to debug that in the evening.

The laser light source is available in BlendLuxCore, it is a bit hidden in the area light settings.

I can't reproduce your wrong spot orientation here, can you post a small test scene that shows the problem?
