Hi Admin,

I have a simple scene with 3 box with the name of 'k1', 'k2' and 'k3'.
Each box's info is located in their MTSInstance Tag. (pic 001)

Let's assume that i forget to creat a group which is make 'k1' as a parent object ,make 'k2'and 'k3' as a child object of 'k1'.
So I changed MTX file, move the codes of 'k2' and 'k3' to the 'k1''s MTSInstance tag.
But the position of these boxes is changed

How can I solve this problem?
Thanks

Another problem is:

I created a dummy object with the name of 'group' and used MTSInstance tag contain all the three boxes.So the 'group' is the parent now.
I want to drag the dummy object to move these 3 boxes at the same time. Is it possible?

I figured out the second problem by setting a target to MTSDrag tag
