Mason: you forgot P5 can also do true reflections (ray tracing). i love Poser 5 even if i've had a lot of problems with it....i just got used to it and just work around em..... the FireFly engine is unrealistic compared to Carrara 2.1....P5 has a weird thing it does when it renders.....the textures get a shade that isnt in the texture map....it ends up looking a bit plastic.....Carrara reveals the true colors of your texture maps....no weird color blending.....Carrara's "Material room" is a nightmare dough....um still trying to get used to it....for instance, in P5 setting up a transparency is very very simple....just open your texture map, the drag a node to the master shader......in Carrara you have to study how to set one up!!! in P5 i was texturing as soon as i installed it!!!
