Nested groups break in Lxs import

[nigec]

Dade fixed groups in lxs imports, however if a group has a group inside it the earlier problem returns
This is what the model should look like

Letters are single groups

As a Sketchup user I use groups, you can not model with it any other way
I thought I could just explode the main group but all it take is a single group with something inside it and it screws up

luxcorerender-v2.2alpha1-win64 which I downloaded this morning

I will check but it may be a problem because in LuxCore you can not have instances of instances (by design) so I will have to flat the groups hierarchy at some point.

[nigec]

It would be great if you could..
Exploding the parent group works, but scenes like below take some doing lol.. I'm also getting to grips with a render view

[Dade]

I added the support for nested group to the LXS parser. It should now work.

[nigec]

Awesome thank you

Hi Dade, it works great, even with Sketchup components
One small problem is lxs emitter materials don't work, in the following example there should be a emitter material cube, but it doesn't show (but its set as null in settings) and casts no light, if I turn off sky/sun its not even a light source.
In the zip the sky is on so it will import

PS, I tried the school corridor scene that comes with Luxrender 1.6 and that also fails to load.. I know I'm being a pain but I'd imagine the first wave of plugins are likely to use old plugins for reference.. ironically my project is failing dismally importing lxs files lol

[B.Y.O.B.]

If I remember correctly, null materials can't emit light in LuxCore.
Use a black matte material instead.

Yes, null material is invisible for all rays so it is like if the object is not there. Can you change the material of the light source or is it done by the exporter ?

[nigec]

ah right, its the exporter, but I can change it I think

Nigec, it would be nice to create a new repository for the SketchUp exporter at https://github.com/LuxCoreRender with an update version. Going trough old LXS format isn't ideal but it is still better than nothing and more user could benefit from this work.
