Can I still ask annoying questions, though? Because I do have one, and I haven't gotten around to searching for the answer yet. How do you make snow in Bryce? I've never really tried. Never had any interest until about three weeks ago, then suddenly started wanting to go make snow.
Snow is really tricky in any application because it's just so damned white, reflective and without proper lighting, featureless.
So really it's about getting a balance of whiteness while keeping detail. I think made more tricky by the fact that Bryce doesn't do Sub Surface Scattering.
There are of course quite a lot of ready made shader mats with snow on them for snow topped mountains etc (see first example below) and if you are using Pro7 and have installed the extra content, you will have access to some of David's excellent pro materials which include several snows (including a groovy 'falling snow' which is a volumetric material that you can put in a slab or sphere to fill your scene with falling snow as in the second example below).
If you wanted to make you own material that allowed you to put snow on the top of objects within your scene, then that's done in the Deep Texture Editor (a scary place) and would involve using slope filters so that your snow only appeared on flat horizontal surfaces while the rest of the object had a regular material showing on it's vertical surfaces.
Chohole also came up with a good way to simulate snow on the branches of the trees in her render above, but I'll let her explain how she did that.
Sorry if this is a bit vague, but I'm hoping David can come along and point to one if his video tutorials.
