That's just daft biggert. If you want to compare P4 effects and P5 effects then you do so on a level playing field - use the P4 renderer in P5. Utilising Firefly as a comparison against P4 is not any more fair than if I was to post the result of my render in Cinema 4D... which would be a fairer comparison considering the grandiose claims made for Firefly. Same with the materials room. In P5 you can layer materials, in P4 you cannot. Apples and Pears. It's not about whether P4 can do P5 effects, it's about you answering your desire to prove P5 superior. That's not a challenge, that's a joke. Now, if you really want to test Firefly, then I suggest you DO take it up against Bryce, Carrara, Shade and other software. Let's see what it can do against a REAL 3D renderer, not the poor little preview render engine in P4 - although it can compete after a fashion.
