I don't think there's any limitation in OpenGL or OpenSG in terms of
numbers of textures you can use, as long as everything fits in memory.
We've used hundreds of textures with hundreds of megabytes of data
without a problem.
Do you get any output in the terminal? When the texture definition fails
it will print out an error message, if you use the debug libraries.
You can also get a pretty extensive log of what's going on by using the
debug libraries and setting the following environment variables:
OSG_LOG_LEVEL to "debug"
OSG_LOG_TYPE to "file"
OSG_LOG_FILE to "osg_problem.log"
If you send us the log-file we can take a look if there are indications
to what the problem might be. Please compress it and send it directly to
me, these things get a little too big for the mailing list. ;)
Yours
Dirk
