Why can't I use more than 229 keyframes?

[6129-screen+shot+2012-12-27+at+5.52.19+pm.png|6129]

As you can see, The animations “getup” and “attack” stop at 229 frames.
When In my 3D program, the animations keyframes are:
“getup”:260-270
“attack”:270-295

Please answer if you have any insight about why they set it to 229keyframe limit or how to increase this integer…

If you use Unity 4 (I use it) and Unity 3 is probably the same thing I don’t remember.

229 means it’s your max length animation, you can’t go after this cause it’s your last keyframe.

If you want go after, add frame in your animation then reimport it in Unity.
