Change number of frames allowed for each animation? I have a shoot animation which contains 15 Keyframes, and a reload that contains 70 keyframes. When I set the keyframe amount to 70 and go to the shoot animation, then change the number of keyframes to 15, only 15 keyframes show up when I go back into the reload animation.
The frame range set on Timeline is for global output range by default. However, if you want to have a alternative preview for certain duration, you may consider to click the Use Preview Range button on the Timeline header.

  

When enabling it, you can set an alternative preview range by setting Start / End value on the header, instead of changing the global output range.
