[osg-users] Large number of occluder nodes

[Robert Osfield]

Hi David,

Your cars could probably by simplified, such as by putting an LOD
above them and have one instance for far away with no, one just one
transparent part and a higher quality version.  Using a texture atlas
is another trick you can use to enable you to merge separate
geometries.

Robert.
