Hmm, well I'm not going to flame you, I just disagree with things like Pro-Render, especially after playing with Maya lately. Also, you really should research Ornlu's work, and a few key other people here who I care deeply for, before saying that we are wrong. TA's falloff is, in fact, squared. I will prove this to you, if logic can possibly prove anything. Unless you are re-coding Bryce 5.01, that is. I've seen no proof of this. So far, your render technique is limited to the above-type scenes, which is cool, but I'm working on a variety of styles and have no time for barriers. I'm really not trying to mock you, or be an elitist about things, but Bryce simply doesn't have photon capabilities yet. After playing with Mental Ray and Final Gather, I have to say that all of your work here is nice, but obsolete in the face of other technologies. The MAIN difference I'm talking about is render time. That's what makes something professional, time is money. You could never, EVER animate the scene you made above. And without being able to animate, there is simply nothing "professional" about "pro render". No offense intended. Perhaps, "Journeyman-Render"? I've got more respect than most for you, don't ruin it by making uneducated comments. Still, I hope this mesh thing works itself out, that's annoying as hell! I'll agree with you on that...! (I don't flame people, I incinerate them)
