A question that bothers me is: When I import obj model, I have all pieces of model grouped in one and don't know how to separate them. I'd like to have trunks and tops separated so I can animate, texture, etc… In original maya file they are separate pieces of geometry.

If using a file SOP, all your geometry by definition is inside a single OBJect. You can, however, create multiple objects and put the same file SOP into each one, and a delete SOP after each to delete everything but the particular portions you consider to be part of that object.
You could probably make a decent case to SESI that their ‘file->import:geometry’ entry should pop up some kind of menu to give you the choice for how finely you want to split up your .obj file into constituent objects based on groups.
You can group by connectivity, and do it that way.
You can also select a face and grow your selection by pressing Shift+G. While you have that selected you can press tab over the 3d viewport and type in “material.” That will allow you to apply a material to that section.
Connectivity is probably easier, but other options are always nice.
thanks, think I'll re-export separate pieces from maya and connect them in houdini. Also I thought using fbx.. but then it's not easy to reload and replace geometry as with objs.
It would definitely be great to see Houdini more friendly when importing objs.

Out of curiosity, what does Maya do if you export an .obj in the same manner and then reimport it?
