You were right!
I'm totally digging Houdini. I do wish its was faster at a few things…. Cloth, Rendering…
Gosh, I hear it often and can't believe what I hear. Mantra is fast, very fast. Couple of companies have jumped recently into Houdini mainly because of that reason. Fast, stable and affordable solution. Once you know how to use it, you will enjoy its power and speed.
I've never heard that PRMan is slow although is as slow as Mantra. Yes, I saw how Modo or mental ray pretend to be fast with GUI interactivity. Well, interactivity doesn't equal speed. I also know couple of projects started in mental ray which had to abandon it due to a serious performance problems in hard rendering.
Mantra doesn't have decent and easy to use GI solution though this is quite common for renderer of its kind (production, micropoly engines). Agree. Mantra doesn't have also any learning materials you could use to prepare your self to work with it. Agree, its a big shame.
