Blender is a free 3-D software that lets you create whatever model you want. Its difficulty is based on how well you know the hot keys. I like to use this program a lot with Garry's Mod to see how well I can make body armor or some kind of car part. I spend most of my time learning more about blender and what I can do with it.
tip 7d10 10 top 3D modeling tips Tip 7: Don't obsess about topology "Aside from in-game assets, don't obsess over topology unless your model is going to be rigged. This can become a huge waste of time. Many artists use ZBrush's decimation master or ZRemesher to create final assets when in a hurry. There are no topology police. Just know how to create good topology for the situations when it matters.” Alex Alvarez
