*ever heard of the chanlum shader* Does it come with C4D? ;) *in a scene where you want a some what realistic looking pool or flow of water* Am I supposed to see caustics in that animation? I see refraction and a particle sytem with metaballs. *I do have poser 5 and love it as well, but I also like working in cinema and using the hdri lighting. Does poser 5 support this?* Not really. But on Windows, you can get pretty close with HDRShop (free) and the ProbeLight node.
