# Modeling 101

That screenshots also shows off my integration of CEGUI  into my WIP. I struggled with two issues that I'll share with people. The first issue was that you need to have the OpenGL viewport set up correctly when initializing CEGUI. Unfortunately my initialization was occurring before I called glViewport, but that was easily resolved. The second thing was that having any VBOs / VAOs bound messes up CEGUI (for now). Be sure to release any bound buffers/arrays before rendering things.
