In Max I convert all materials to standard materials and export as obj then I use SIM lab to save it as skp. I think I get components through ok that way. At least I havent noticed anything but it was some time since I converted anything so I might be wrong.

Hi Pixero! Yes I convert all materials to standard materials too. And now I tried converting OBJ format to skp in simlab composer. it did a good job and everything is fine! all instances are components in Sketchup format. Thanks for the pro tips! 👍
