I have Animation Master (from Art Electric here in the UK) and was thinking of buying some ready made models for the boring props and stuff so I can concentrate on building characters. I noticed Viewpoint DataLabs offer their models in Playmation format (I suppose they mean SEG format) but I wondered, since they are probably polygon-derived, if they are so large as to be unworkable. I recently imported a 5000+ point DXF and it took 45 minutes and was impossible to work with (only a 33MHz 486 PC- but even so). So my 3 questions are: Do you know if the Viewpoint people reduce the control points in their Playmation format models to make proper use of spline features? Can you recommend a sensible maximum number of polygon vertices for import? Is there a good supplier of proper ready-made spline models for Playmation or A:M, as opposed to just conversions from polygon models? Any info. would be much appreciated.
