Hi Alistair, FYI, OpenGL has a texture feature called proxy textures where you can do a trial texture allocation and then query whether that are real texture with the same parameters will succeed. This feature isn't utilized by the OSG so it's something you'd have to roll your own OpenGL code to do the query. It's probably over 15 years since I look at this particular annex of OpenGL so there is chance that modern drives don't support it. It might be useful though if it's still supported.
