I am just now bestowing upon myself, the virtues of the 68030 card and having a great deal of fun with Silver. After playing endlessly with various indexes of refraction, I have managed to actually create spheres that look like glass. Unfortunately, I cannot make my other problem go away. That is, I cannot get spheres which are above, below, or to one side of the camera, to look ROUND. They always come out looking like eggs, oblong, and not terribly round. I have tried to make sense of the manual to this end, but alas, nothing I have tried seems to work. I would be ever so greatful if you could point me in the right direction.

Jim, I wish all questions were this easy! You've got to adjust the focal length of your camera. In SV, which you should be using, "normal" view is 1.5 on Z. Anything smaller is wide angle. Large values reduce the distortion you are seeing. –Rick

Thanks! that does clear up a lot of problems. I have tried it, and it works. Much thanks to the other chap who replied as well…your help is much apreciated. In my efforts to render nice pictures, I have come across two other small problems. I seem to be unable to get sufficient ambient light…I can never get the picture to be terribly bright naturally, such as ambient light is supposed to do for me. I am unclear on how that is controlled. I dont have SV yet, just turbo 3.0 My second problem is, I still cant get IFF brushes to wrap onto anything.. I have tried following the tips in the manual, but I cant even get them to appear, let alone getting positioning correct. Is there something obvious I am missing? (p.s. I think you should still ship that nifty bag of marbles with your Silver packages…I loved it when I got mine that way!) Jim CBM Ottawa

Jim, you might consider purchasing my tape "The World of Turbo Silver." I think I cover the brush wrapping pretty clearly there. Just remember, the orientation of your axis must be as stated in the manual. Second, remember to scale your axis large enough to cover the object's surface. –Rick

Rick…sounds great. I think I would like to get my hands on this tape, I dont think that CBM Canada has one (at least our office here in Ottawa doesnt) so could you please leave the particulars on how much, address and particulars? Will you take visa over the phone? Jim CBM Ottawa

Call Impulse at 800-328-0184 for all the details. CBM USA has never bought a tape either, although I know a couple of staffers who have purchased it. –Rick

Rick.. I havent even tried this number, but I am willing to bet dollars to donuts that it doesnt work in Canada. Can you give me the local access number please? Jim CBM Ottawa

I have had some luck when I consider the value in the "focal length" position of the Camera requester (F5) to be the actual camera focal length times 10. So a 550 in that spot coincides with a 55mm focal length. I had to then move the camera somewhat, but overall, it lends a measure of consistency to the process. I was not paying much attention to the viewpoint values you mention, Rick, but it occurs to me now ( a light!) that that is the viewpoint offset from the actual camera icon in the editor window. Amazing! I'm sure glad I spend the dough to hang around here, I absorb alot of good info! Scott
