hey,
i'm learning about rigging in xsi and i wanted to postion contrain an object between two other objects. so i create the tow position contraints and set the blend value of each to 0.5. i expected this to centre the object. but instead i found that a value of 1 in one of the blending values and the other set to 0.5 moved the object to centre. i thought the blend values would have to have added together to create 1. could someone explain to me why it is like this.

thanks
adam

The constraints in XSI work like that: if you got two position constraints, one after the other, for instance, the later constraint is always blending against the one before it.
So, you need to leave the first createad constraint on 1, and lower the second one's blend to 0.5

If you want to blend an object between two other objects, why not use : Constraint 2 points,
it's much easier..

cheers for the info. i'll look at the constrain 2 points method

You can do it manually.

Create one cluster with center for each end point of a curve/path and then constrain your object to that path and set the % to 50. When you move the nulls of the clusters you'll allways have your object at .5 or 50% of that curve/path (2 point constraint).

That way you'll have what you want with much more control over what's happening.

Cheers.
