Foleypro refers to female mammary glands and gluteui, CrazyDawg. I suppose he could be referring to male-such-areas, as well! (joking) TA is short for True Ambience, one of Bryce 5's so-called premium render settings. It's a fun effect, but drives render times so far up as to be completely useless in animation. But it can be great for still-shots! TA only works when a scene is very small, otherwise the falloff rate, which is squared, defeats it's effects. We have been using TA to achieve a varied sort of radiosity in Bryce for the last few years. Search up True Ambience on the Bryce forum, there's a slew of threads describing it and how to use it...
