i exported the model from IC7 via livelink can anybody help and tell me how to get rid of them? thanks.

Looks like you have reach effectors still attached to avatar. If you enable them accidentally at some point, then delete Reach_Dummy structure attached to avatar.
If you are actively using them, then Collect Clip and save as Motion+ (making sure Bake Constraint Key is checked), then clear the motion, delete Reach_Dummy, reapply saved clip and the "livelink".
(Unless there is a way to disable effectors via livelink, which I am not aware, as I do not have the plugin :))

hi thanks for this quick tip..still a noob with this are their any quick method just to hide them or delete them in unreal? thanks so much.

There probably is, but I'd rather have someone involved with UE to answer. Might even turn out those are something else, other than Reach Dummies :)

thanks again..will read some more on it :)
