I have imported an adobe fuse/mixamo character/armature/fbx file into blender and I realized that the arms pass through the thigh,as you can see here :
I would like to rotate the arms on the x axis a little upper in pose mode,but since the animation has 288 frames,should I do it for each frame ? It will take a lot of time !!!. I changed the first and the last frame only,but the frames on the middle aren't changed. I don't know why. Is there a faster way ? thanks. You can find the fbx file here.
