Thank you an0malaus. I always use a nul cr2 container to put props together. It's easy to use and you can hide the group easily in a heavy scene (some of my scenes can be more than 1 Go ). It's the reason I have a figure number. See my free stuff: https://www.renderosity.com/mod/freestuff/pendule-murale---wall-clock/82482 Then you can have ERC in the figure body and lights. I think it's better than the Poser grouping tools. Thank you Biscuits, but the geometry stripper works only in Window. And anyway it's no very hard to write Poser code.
