This is actually what I tried. The issue texture->getTextureObject(contextID) returns 0, which I assume means a null pointer?
I create my gc manually then create viewer/window etc... so my code looks like this: unsigned int contextID = gc.get()->getState()->getContextID() unsigned int textureID = texture[0]->getTextureObject(contextID)->id(); Upon executing the "textureID = " I get a seg fault, and upon further checking, texture[0]->getTextureObject(contextID) = 0.
