Using GPU with 0.8dev versions

I noticed that only objects with an non applied modifier appear (solidify), I tested with a lonesome building it works

Can you reproduce the problem in a simple scene (i.e. a cube over a plane) and post the scene luxrender files ?

When I launch a basic scene (cube + sun + camera) luxrender crashes with this message :

terminate called after throwing an instance of 'std::runtime_error'
what(): An empty DataSet can not be preprocessed

I need the "untitled.Scene.00001.lxo" file too, it is the one where the geometry is stored (i.e. where the problem should be).

Hello,

I've added the file here.

I've added the file here.

Your cube is an instanced object (see the ObjectInstance "Cube_Material" in the .lxo file) and instances are not yet supported by hybrid render (i.e. the instanced objects are ignored at the moment leading to a totally empty scene in your case).

Maybe I don't really understand what instances are.

I thought an instance was a copy of another object with the same properties.

Actually this is the original cube of the default blender scene. How could it be a copy of another cube ? And how to define it another way and tell blender it's not an instance ?

I've built each object of my scene after importing a .dxf, and separating each object with the P shortcut. I thought there would be no instances. Now I understand that all my scene was built with instances. How can I really separate objects ?

Regards,

Archimage

You can have any number of instances of an instanced object, including only one. Are you exporting for normal rendering and than editing the file to switch to hybrid rendering ? Because LuxBlend 2.5 would export everything as an instance in that case (some detail available here: viewtopic.php?f=11&t=4516&start=150#p56770).

I'm not saying you are creating intentionally an instanced object, it could be just an exporter issue/bug.

[archimage]

Yes it's the case, I export then edit the file manually ! Now I understand...

Is there a way to export from blender directly ? I can't find hybrid mode in the exporter

Thank you for your answers !

Yes, but you need PyLux enabled and up to date for it to show you the options. Otherwise it reverts to 0.7.1 compatibility mode and hides all the new goodies

Thank you everyone it worked finally !

I've noticed a new problem, when I activate the glass material everything in the scene goes transparent, am I missing something ?
