hm, I've loaded the .osb with the two of the test programs
(testStatisticsRender and testVRMLRender - which is not really VRML
specific...). Both already add a light to scene so there were complaints
from OpenGL about unknown enums, when GL_LIGHT0 + 8 was passed to
glEnable for the last (9th total) light in your scene - which is ok and
expected.
A bit strange was that only one of the two programs actually complained
from the RenderAction, which normally already detects if there are more
lights than OpenGL can handle in a scene. So it seems that there is
possibly something wrong with the way lights are counted, but I've not
had a chance to investigate it yet, sorry.
Cheers,
Carsten
