Hi, Robert
I have found that ive and osg does not store/read pointSprite selection flag
for osgSim::LightPointNode. Attached are modifications in ive & osg osgSim
plugins.
I susppose this modification breaks backward compatibility. I don't know whats
your policy in such cases. Is there an option to test file version and parse &
interpret data conditionally ?
Cheers,
Wojtek
