Problem with skeleton being offset from source

[Anonymous]

Hey guys. This is probably a common problem but I'm new and not sure how to fix it.

I have a robot set up in HumanIK and a mocap animation that I'm using as a source. The robot and the mocap both start in a T-pose, but when I set the source I get this:

The skeleton with the arms forward is the mocap source and is correct. The robot is somehow offset from that.

How do I fix this?

Bump. What do I need to do?

Hello,

It is not clear looking at the video what needs to be done.  What does the robot look like in a t-stance?  Is it a biped and should it match the mocap skeleton perfectly?

You could try clicking on the 'match source' option in the HIK properties tab < retarget specific of the AE for the robot.  But, looking at the robot body which looks a bit mangled, I think there is something with the character set up.

Any chance you could send me the file?

Here's the robot and his skeleton in the t-pose.

Essentially what's happening is that the robot and the mocap data both start in a t-pose, but on frame zero the robot's arms go straight up when the mocap animation is set as a source.

Still trying hard to solve this but I don't know what the cause of it might be. Does anyone have any suggestions?

not sure if this was a similar problem to my own?

went to node HIKproperties

Match Source from Off to On.

It absolutely was, thank you so much for that. I had no idea that big panel of options existed.

Thank you so much everyone!

Dang it. Overnight it stopped working again. Now when I do "Match Source -> On" on the character basically nothing happens, or if anything does it's very minor and it looks more or less like it did before. I've tried removing and re-adding the source, I'm pretty much back to square one.

I have not been able to find out what is wrong.

You can see that I have "Match Source" turned ON, but the two skeletons do not match up. Match source does exactly nothing. (Unselected is mocap source, selected is current HIK character).

Is there something else I have to do?

Well, I solved it.

It seems like the base skeleton I was using as the HIK character for the animation clip was broken somehow. I replaced it and everything came right. Non-issue. Thanks everyone!
