I drafted a stage using the stage deck insert, pick the 3d Options button, and clicked the associating textures. However, my stage stays white in left isometric. It is in OpenGL, I have tried selecting the 3D options then a texture, I have tried leaving the 3D options set to black, and I have tried using fill color. It has remained white every time. Thoughts? (It has an orange frame in the pic because I have my mouse over it. There are actually several other decks there.) Open GL options set to 'use texture' and 'use color' but no other choices are select-able.
