Since I upgraded my system from OS 8.6 to OS9.0.4 I don't see anything on my screen when trying to render with Quickdraw 3d interactive renderer. Lightworks raymaker just works fine (renderworks installed).
In the past I had the same problem but could fix it by giving more memory to Vectorworks. This time I have no success doing so.
(320MB Ram installed, 128MB allocated to VW)
