I am facing difficulties to use Poly Reducer script in current Blender version (v2.71). When I selecting my mesh Edit Mode, I do not see any "Script Window" options inside Mesh menu. I also found in Blender Wiki that this script is included only in versions 2.42a - 2.46. Unfortunately v2.46 is not supported on my Mac (I tried that).

So I was interested if there is a way to use Poly Reducer script with current Blender version? If yes, how? If no - are there alternative options in Blender to reduce polygons?

  • $\begingroup$ That script is very old and only works in versions up to 2.49b. It's since been replaced by the built in decimate modifier as GiantCowFilms mentioned. $\endgroup$

The decimate modifier is the closet alternative. I find Un-subdivide to be the best(using even numbers of iterations generally creates better results), the other methods are good to, just try all of them for the best results.

Note, in Blender 2.4x the decimator didn't support UV's, vertex groups and it triangulated everything, however the decimator now supports these - so there is no need for the script.

  • $\begingroup$ The Decimate Modifier won't work with Shape Keys. You can however go into Edit mode, and do Decimate Geometry in there, that does work with Shape Keys. $\endgroup$
