Thank you, thats a good idea, too.

I did discover what I had done that messed up the works so badly to begin with. The good news is - the dark rose foot pose does seem to work well But - here's where I screwed up. I reposed the character after using it and forgot that, logically, one would have to repose the feet with the dark rose foot pose afterward. To help with the stabbing through the floor issue I loaded a floor prop which helped to give me a bit more perspective, then as hornet3d suggested, used a camera below the floor to adjust where the model was.

Thanks to everyone for all the great replies, I think this is the first time I've ever used a whole outfit without major poke through issues to try to solve with post work which is extremely good because my postworking skills are pretty much non-existant!

thanks again :)
