hi! It seems that pdmtl really needs to have multi-level namespaces. Perhaps in May we could work on making that happen. .hc Do you mean something such as [pdmtl/gems/duplicate] or [gems/pix/sobel] ? Both already possible. Maybe you mean [import pdmtl/gems] and then [duplicate] ? Ah ! very

Wings3d is a modeller which can export .obj files with groups which can be animated with gem. But each group is a distinct step/frame without interpolation in between so dont expect to much from it... Cheers, Malte -- Malte Steiner media art + development -www.block4.com-

Ok, yes. After tinkering last night a bit I found that it is indeed this simple. For some reason I was getting confused, based upon where I was putting the separators for different branches of the structure. I like this top-down approach. It makes it easy to add global modifiers at the top of the

Roman is right, just parenting down the chain, with small sphere (proxy geometry) to change the pivot control, from the center to one end. where separators come into play is to branch off arms and legs from the main body. The body's transform will still control the arm, but sibling hierarchies

One trick I found from rigging models in gem, is to create a small sphere at the location of the pivot and then parent the geometry into that. Then if you rotate the sphere it is rotate its child geos. For the helicopter blade you don't need to do this, as long as the pivot is in the center of
