Well, you can get almost total realism in most things in Bryce, if you have the patience! Volumetric skies are easy to create and can be extremely impressive, but they take hours or days to render. Using the Skylab is fast, yes, but it only produces the most basic of effects. A faster, more efficient render engine would be most productive improvement that could come out of Bryce 6. Even using a high-end PC there are numerous functions I can't use in B5 because they take too long. Not much point in adding any more - we need to be able to use the ones we have first! As for landscapes, Bryce is at present an object-oriented package and therefore terrains are objects too. I can't imagine any images that could be restricted by the size of terrains available unless you're running 128K or something, it's just a case of positioning them carefully. Having said that, the terrain painter is total garbage. A single, smooth circular brush with naff-all control - urgh! If Corel do only one thing in B6, I hope it's to fix this!
