Add translate attrib to relative Trax clip = mess

[zqw]

I made a walk cycle clip for my human character.
The clip offset is relative so I can cycle it.
Like most people, his pelvis.translateY = 17 when standing.

I want to add a little bounce to the walk, but pelvis.ty is not in the clip. So I pick the clip in Trax, Modify->Activate. Set start and end keys at pelvis.ty = 17.
Now, when I deactivate the clip, he pops up to 34.

So, I can set the pelvis.ty keys to 0 in the clip, but next time I make it active to tweak, he's scraping his bits on the ground (pelvis.ty = 0). ow.

I'd like it to behave like the other attributes in there.
For expample, his pelvis.rx starts at -10 in the clip. And, in the pose before the walk clip his pelvis.rx = -10. But it doesn't jump to -20 at the start of the clip.

help!

Well I managed to solve it. This post is for future generations using the search function.

To add a new attribute to a Trax clip:
Make the clip active (puts keys in the timeline.)
Add Keys for the new attribute.
CREATE a new clip.
Delete the old clip, and replace with the new one.

Maya apparently only does the intuitive/magical/hidden absolute/relative thing during clip creation. It's sorta like it builds a starting pose into the clip, so relative movements work ok after that point.

So, active clips are for tweaking existing attributes/curves, NOT for adding new attributes.
