I'm working on a large architectural model and it is taking a **long** time to render (about 90 min/frame). I've been looking at the manuals to see what I can do to speed things up, but I did notice something that I was wondering about. In the model the only thing that moves is the camera, and the renderer seems to spend a lot of time calculating shadow maps for each frame. (I have the system maxed out at 32 MB of RAM and it generates a 22 MB swap file on this model. Replacing the CPU card and adding more memory isn't an option right now, particularly in light of our current budget/staffing problems) Why does it keep calculating new maps for every frame (or maybe field)? Do they change from one to another if only the camera moves? Chris – Chris Johnston, Written 28-Feb-1995 @ 21:19:12 Using: Windows NavCIS PRO 1.5
