I am having a problem with the poses I am making. I upload the animations, set the properties to copy/mod, add them to a ball, set the properties to copy/mod and link them. All copy/mod. The problem is in the testing. I hand them to my partner and she rezzes them and they are no longer in the position I set them at. I can pull it out of my inventory and they are correct and exactly at the same height I linked them at. This doesn't happen with all of the linked poses, just some? I don't get it at all. I'm working on a 3 person pose and it comes out perfect if I rezz it but again, if she does, 2 ppl are in the right place but the 3rd is to high. I have had this happen with 2 person poses as well. Some input on this would be great and very appreciated. Thank you.
