Thank you for your comments !

Problems ? With the auto-save ?? Um, yes, I've a fairly fast AMD system with 8 cores & 32 GB RAM, but saving scenes in PP11 is a lot slower than I'd hoped.

Doesn't help that my twin GPU cards can't multi-task. If I want to do do 'other stuff', I must render using CPU, as that has cores to spare...

Hmm. Will PP render in background using GPUs ? They're both GTX 750 Ti, should be able to support 'people speed' stuff as well as rendering. Unless they don't, but scant clue in the manual. At least, nothing I can FIND....

( US manual, US 'sort the headings' index. But, unless you know the manual so well you don't need the index, you don't know what to hunt... )

OT: Really annoying that Poser manual has so many gaps and 'hand waves'. Perhaps now Renderosity has taken over, more info will be added. And index / search key-words padded out, so a search for eg light emitters or extreme ambient values would actually find something useful, rather than yet-another two-line hand-wave.

And rigging ?? I've recently dug back along my shelves, found several Poser 7 books I'd forgotten about. They actually make sense, unlike PP manual's 'one approach fits all'... ( I did a lot with P4, had bought but not installed P7, when a spate of dire HDD crashes plus unexpected 'family matters' took me out of CAD etc for a decade... )

Sorry for mutterings, I get so exasperated, and my 'must figure this' list keeps growing... Nik
