Eric Neill said over 11 years ago:I'm surprised more people haven't reviewed this! A great tool for production retopology. I find most modelers who retopologize forget a very important problem. VOLUME! I've tried many techniques to get around this at work and in my own personal projects. I feel that with this script you won't have to smooth your model, then shrinkwrap then go back to level zero again, (it does work but it is very slow!) I tested out the script on a basic problem that faces just about every modeler out there. I did a simple test where I smoothed a cube once, twice, 3 times etc and shrink wrapped each around a very dense perfect sphere primative. I then calculated their surface areas before and after running this handy script. As you would expect, the denser the mesh that you shrink wrap, the more accurate the results. What I found interesting was the script makes the cube that was smoothed maybe 1-2 times more accurate in volume than a cube that was shrink wrapped after 5 smooths without the script. I also did another test which would be more applicable for retopologizing scan data or a zbrush sculpt, in which some areas have much more density of polygons than others, such as eyes/ears etc. Again I ran a surface area check and it did its job just as with the sphere test. The only problem in this test was that the areas with higher density such as a valley of 3 edgeloops to define a crease, the script caused these areas to overlap, but when smoothed it would correct this. In production work we obviously would need to correct the overlapping for a proper uv distribution as well as for animation. HOWEVER I do feel that running the script and fixing these problems could still save a lot of time where you would otherwise be painstakingly sculpting and tweaking the smooth proxy to line up just right.
