Can not generate scene #31

Closed 4lukashchuk closed 4 years ago

Hello all,

Would be grateful if you might help me...

I obtained an .obj file from .dae in blender (before, it worked nicely with multiple formats) and tried to visualize it in helios for lidar simulation. But the problem is that the script can not generate a scene file, giving ---> see below --->

Let me know if you have any ideas, Best, Anton

Hello @leokurchatov ,

It seems that HELIOS cannot find a material's path when serializing the scene.

Can you provide the generated .obj/.mtl files from Blender?

Also, can you show the full HELIOS output? the content before # primitives loaded might be helpful.

Best.

I will close this issue as it seems inactive and probably has become obsolete. Don't hesitate to re-open it, if the issue is not solved.

Dear @deuxbot as well as Helios team, Sorry for the delayed reply,

Apparently, the problem appeared if I created a 3D object in Blender with all the shadows, reflections and so kind of information about the object. At some point Helios could not image the scene, or sometimes when it managed to do that, the scene had excess layers which completely ruined the full picture. If I however simplify the object in Blender, that I have a basic shape only and few more minor properties Helios can properly image the scene.

Best, Anton
