Need Help with Parenting Constraint!!!

Note: I can't figure out what changed here - I can't upload a scene file.

So, in absence of that, I'll try and describe this issue:

I'm trying to use the constraint tag, to parent an object to another while the second one impacts the first. Simple, right?
It works, except for when I get the timeline back to zero, at which point the child object (with the constraint tag) wigs out and jumps position. None of this makes sense, as I'm using all the default settings in the tag, just like their C4D instructions show.

Anyone have any suggestions as to what common mistakes I might be making?

And, where the heck changed with attachments? I've tried the "upload an image" 50-times, but it won't accept my zipped scene file.

What you have is a priority problem. Just make sure the parent is at the top of the child in the hierarchy.*

Thanks for the advice. I'll have to go into the project and check whether I missed that. But, I think I already had the parent at the top...

parent tag is very unstable, use this method instead:*http://ace5studios.com/picking-things-up-in-cinema4d/

Hey, thanks! Nice tutorial. I'll try that, when I get a chance. Interesting, though, that it's still utilizing the same constraint tag. I wouldn't have thought that the specific parameters (parent, PSR, clamp, aim, etc) would ultimate change the underlying code going into the animation. But maybe so?

Which version are you using? Parent constraint should be quite stable since R18. I also have made a tutorial about it:

Other than that, the description wasn't very clear. An example of the effect you're trying to achieve would help to give you more precise directions.

Nice tut. Nice implementation! Haven't used it in R18 so far

R17 - So I don't benefit from whatever improvements were made with R18.

If you'll notice, I specifically added that I was (and still am) not clear on what happened to the forum attachment process. I can only see an option to post an image, not a scene file. When I try to post a zipped scene file, nothing happens. This, is why I didn't post an example.*

But AlekseyVoz totally solved this for me, with his great tutorial. Simply using "PSR" inside the Constraint tag, instead of "Parent" totally fixes my immediate issues. The only thing I did differently than what he explained, was I simply keyframed the position and rotation switches, as opposed to the strength sliders. I wasn't quite fond of his single-frame offset between 0-100%. But that's just me.
