MilkShape 3D - маленький, но очень интересный редактор 3D моделей. С его помощью можно делать и конвертировать модели для таких игр как CS, half-life, the sims, Quake, Serious Sam и тд, а также создавать модели с нуля.

MilkShape 3D (MS3D) is a Shareware low polygon 3D modelling program created by Mete Ciragan. It is used mainly by people compiling models for Half-Life, Blockland and other sandbox games. Milkshape 3D's repertoire of export capabilities has been extended considerably, due to the efforts of both its creator and the community around it, and it is now able to be used for most games today, so long as an exporter for the required format is available.
