Hi Quest, Thanks so much for your reply quest . Whats happening is that when i have imported the OBJ in Bryce the groups dont scatter all over the place but they remain together . Only the oter group that which holds the inner groups remain. when when i remove the oter group i find theres no existance of inner groups. all have become individual objects. Thus then i have to r.click choose the individual objects and then apply material ( at Bryce). have heard there is a function in Bryce 5 where u can have a list of all the objects in the scene ,(just like Max) and then select the necessary ones and regroup them. Can u tell me how to do that ??? Also how to reset Xform in Bryce , as you have mentioned. waiting for all the replies...........
