Poser 5 does not use .rsr files. If I create a figure/prop and save it to a library, only a PNG and a cr2/obj pair (figrues) or pp2 (props) are created. I have only encountered "out of memory" errors in Poser 5 when rendering very complicated scenes using the P4 render engine. Probably because Poser was exceeding the limit of 2Gb per app limit of Windows. This does not happen with Firefly.

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
