I've purchased a few items from the store and download freestuff items that I'm shocked at the poly counts. I'm not going to mention any particular items but instead want to make a general plea to modellers to try your best to reduce polygon counts when possible, especially purchased items. There are times you need large amounts of polygons (like on curved surfaces etc..) but most of the time the multi poly smoothed surfaces I've seen could have been done with 1/4 the polygons with the same effects, some with just 2 triangles. Cylinder sections with 64 to 128 cap sections and sides, boxes with 128 to 256 faces across each face etc.. and these are small items on a much larger model. Now I know Poser likes hi poly surfaces for vertex lighting and shadow effects but there's a point where this becomes way unproductive. Some items obviously have way too many polys for what they are. Putting 4000 polygons on a tassle for a hat does no good what so ever. One item I grabbed a while ago was a valve handle (no larger than a human chest) yet it had so many polygons for the donut-handle part that my poser sat for several minutes loading it. 4000 polygons means 3 vertex coords (3 floats at 4 bytes each), 3 texture coords (again 3 floats at 4 byutes each) and three normals for each vertex (3x4). That 12+12+12=36 bytes per vertex. If poser uses one normal per face then you can drop 8 bytes. 36*4000=144000 bytes for that one item. Now I'm sure poser is using shared vertex tables and such so that cuts down on the poly count but if these are all unique vertices that's 144k of memory right there. Imagine that's one handle on a much larger machine. Our its four stands of hair on a wig. When modelling just ask yourself how important is the surface and whether a low poly version would work better. This will help a lot of user out there with slower machines and machines with less memory. Thanks
