I try and animate a character (from MakeHuman if that helps), I press “I” and select “LocRot”.
I find sometimes that the previous key frame disappears (as in the key frame marker) or that the info that the previous key frame held disappears (as in if i lift the leg of the character on the 5th key frame and go back to the 1st key frame, I seem to have altered the 1st key frame somehow, because the leg is already lifted on the 1st key frame and I seem to have wiped the info that each key frame after that held).
In case i’m doing something in the wrong order, here’s my “working out”:
1). I go to desired frame.
2). Move the character to desired pose.
3). Then insert the key frame.
THIS is what I do from opening blender to the “error”:
Clearer demonstration (Hopefully):
1). Open Blender
2). Delete cube
3). Enable Rigify
4). Import *.mhx file
5). Make sure i’m on frame 1 and pose character
6). Insert key frame on frame 1 (I > LocRot)
7). Move to frame 5 and pose character
8). Insert key frame on frame 5 (I> LocRot)
9). Got to key frame 1
10). Only the second pose exists.
To be fair, it may be after the 3rd or 4th keyframe that the loss of information (keyframes wiped) happens.
Although I can animate a cube as long as I want (multiple key frames) and it doesn’t happen.
Hope that helps you help me! lol
