Now that I had the wierd failure to work earlier and have seen the hirarchy editor window showing 2 different arrangements in a working and non-working config, I think I understand this item a little better. The lights are all pre-parented as a group to fireLIGHT_1 when imported, and parenting the fireLIGHT_1 to the fireCORE and then the core to the lightprop makes one group item that can be moved as a whole by selecting the prop that all other items are tied to either directly or thru fireLIGHT_1 Now ill know to always confirm that the fireCORE retained parentage to the prop and avoid the error I had earlier. richardson, do you have any links to pics that have used the transmap only or the 90degree trick? Id like to see what you are describing :) Logan
