Um... in this type of usage it may well be the easier to have multiple viewers. When you are doing your browser plugin how to you manage the graphics contexts? > Interesting update to the problem though; it seems not related to the > embedding of the textures within the IVE, but more to do with the way IVE > reader creates images.

I suspect the problem may well be down to the OpenGL object ID's for the texture objects being shared inappropriately in your application. The is designed to use a different osg::State::ContextID value for each context, if different contexts use the same value for ContextID then they will share the same OpenGL object ID's which will introduce errors like you've seen. It's not the only way to create the errors, so it's only a hunch on my part. Anyway I don't think there is anything particularly wrong with .ive plugin or the models, all they will be doing is providing us with hints as to what is wrong at a higher level.
