Any idea of how to make a run animation on a soldier model`INSIDE unity 3d?` If I'll need to rig the model PLEASE TELL ME HOW TO DO IT INSIDE UNITY. Thanks
Um, I'm pretty sure that you have to do the Rigging in a 3D Application like Maya or 3DS Max.
If you don't have either of those 3D Modeling apps, you can try Blender and then export your model as an .FBX for inclusion in your Unity file.
I also highly suggest modeling a rigged model in one of those apps rather than using Unity's animation window.
