View Full Version : Issue with 50-50 pos constraint

08 August 2011, 03:00 PM
Hello all!

I'm actually having big troubles with a 50%-50% constrain ( with 2 objects ). My English is not really good, sorry for possible syntax errors.

I have a bullets-chain ( Gatling like ) where each bullet have a path constraint with an offset. The path itself have a splineIK with 3 helpers.

I have 2 main object, the object 1 is the base, where the 1st helper is linked, ans the Object 2 is a vertical moving object, where the Helper 3 is linked.

When I move the object 2, I want the bullet chain to extend. It works fine, but I want a smooth result, so I tried to pos-constraint the 2nd Helper to both the Obj1 and Obj2, 50% for each.

It works, but when I start moving the Obj 1, precisely rotating it, the bullet chain is totally broken.

I've tried wire-param, script controllers, etc... I really can't figure it out.

Here is a picture for helping you better understand the issue:

If you need more infos, just let me know!

Thanks for taking the time to read my post, and for helping!

No ideas ? Or even a suggestion I could try? Maybe my screens are not very clear, Here is a MAX file if you want to take a look. (

( Try rotate the MASTER controller, you'll imediately see that the bullet chains are broken )

Thanks again for helping!
