The functions were already posted in a previous thread, but they seemd to produce some errors. This is solved by just resetting the SetBlend to SolidBlend before rendering the 3D part.
Nice work! Really need 2D. What do I do? Do I just pop the above function into MiniB3D or do I need the functions already posted in a previous thread as well? How do I use Max2D with MiniB3D?
Hopefully simonh will integrate this in 0.40.
