in MapBuilder there is a fully animated free soldier model converted by Painkiller from a mixamo or unity... you can retexture it to be more unique, and replace the weapon easily.
Ok. I've already downloaded it and will check that. Nice tool btw
but as fogman mentioned, Fragmotion is ideal to work with non-animated models and with free motion capture (mostly .bvh) animation files.
The problem is that the required animation is like: "stand" ,"StandAttack" ,"walk", "WalkAttack" ,got it? I will spend hard time getting BVH files for it. I can get the mesh & texture SO EASILY ,but the animation will still be an obstacle. I used to have a friend of mine (artist) working with me, but he apologized for some serious personal reasons.
I will wait for some days. If no one accepted, I will try your suggestions and others that are told to me ...
Thank you all for your suggestions
