things I have tried that did not work:
- models['cooridor1'].disable(viz.RENDERING)
- models['cooridor1'].visible(viz.OFF)
- I also tried moving the models to a different position when they are not visible.
- There are no lights in the scene (I exported the baked scene from 3ds max without the lights). Exporting with lights did make a difference though
Thanks again! Happy for any idea or advice.
