Has anyone had great success with RPC trees, I have been using all of my RPC people (Hint, create one person with 30 different types for all of your people in one file).
I have created an RPC tree with 20 different types for all of my different trees. When I render one it is OK if I put 10 in a scene Revit 6.1 disappears, no warning no error message. If I render the one tree again and again it eventualy just renders as a grey rectangle and then the next time revit dies and dissappears again.
Very strange behaviour
