Interesting info, thank you. I am just trying to set the local location, are you saying I have to GET it before I can SET? I would think the function would work as if just entering it in the edit window.
Anyone know of this issue or a workaround? I am trying to use llSetLinkPrimitiveParams() from a script in the root object to move a child prim using PRIM_POSITION. Changing PRIM_SIZE with this function works fine so I know my syntax and vector values are correct. The child prim just does not move using PRIM_POSITION. Is this a known bug or is there another approach I should be using?
