When I prepare this animation it was like this in 3ds max (http://i.hizliresim.com/0lXBqY.png) but when I export it it looks like to this in fbx file this is the problem how can I fix it ? (http://i.hizliresim.com/VPOMVB.png) look at the hands problem is about exporting to fbx probably
Problem is about FBX not about Unity I exported my animation to FBX and I opened it in 3ds max again and this time problem was there so it is about FBX or exporting settings
Fbx converts all bones to a straight hierarchy with forward kinematics. So anything fancy will be stripped out. Best bet (for ANY game) is to look for an example hierarchy to start with.
