Hello Carsten, the 8 light sources form a chain. Unfortunately I don't have a debug version of OpenSG here. For your information I have exported my whole test scene to an osb file, which is attached to this mail. Hope this helps to find the problem. The test scene looks like this:
Node (Transform)
Node (PointLight)
Node (PointLight)
Node (PointLight)
Node (PointLight)
Node (PointLight)
Node (PointLight)
Node (PointLight)
Node (PointLight)
Node (Transform)
Node (Transform)
Node (Group)
Node (MaterialGroup)
Node (Geometry)
Node (Transform)
Node (Transform)
Node (Transform)
Node (Transform)
Node (Transform)
Node (Transform)
Node (Transform)
Node (Transform)
- The first node is our root
- Followed by all 8 light sources
- Below the light source comes our test object, a simple cube
- The last 8 transform nodes are used as light source beacons
If you wish I can try to copy the relevant source code parts from our
application.
regards,
Michael
