I thought about having CRPro convert bum to jpeg to bum when required but decided against it in the end. Sure... it's easy (if a little time consuming!) to load a bum in Psp and save as jpeg but I'm not convinced that the results are the same when rendered. There's a very useful thread somewhere in the Poser Technical Forum... somewhere! But when you have converted some files, if you remove or re-name the old bum files, then a scan with CRPro with 'Prefer jpeg bump references' checked will change the references to point to the jpegs if they are there. Hmmm... I'm still doing my sums re the price...The weak dollar is biting us European merchants at the moment! Ouch! But I think it will be reasonable: under or around $20. H:))
