Thanks .I think the rectangular holes bug is sometime still there with obj format(sometime also i regret bying PPP)But Cheers seems to get right for my problem:PPP load jpg format as bump map so Vue import it and did not ask for when loading obj file.Before, with bum format ,when loading, i always check no when Vue can not load the .bum format and it cannot read,so bump map was not loaded.I have put no bump in Poser ,everywhere, before exporting and no problem with it in Vue now.Thanks for answering
