Alan,
This is most likely due to the number of texture units you have
available. To check this, try:
osg::Texture::Extensions* textureExt =
osg::Texture::getExtensions(0, true);
int num_units = textureExt->numTextureUnits();
Note that you'll need a valid graphics context.

Subject: [osg-users] TexGenNode and TexGen
I created a forest base using TexGenNode to representing the shading on
the landscape.
It works fine, but when trying to do a number using texture units from 1
to n, I cannot get more than 3 bases to appear.
Is this related to the limit GL_MAX_TEXTURE_UNITS or something more
subtle that I am missing.
I am on v1.2.
