Most of my wishes come from comparisons to World Builder, which I think is overpriced and has an inferior renderer to Vue4. * Area definition, including the ability to define a separate material for an area and constrain the scatter/replicate function to an area. It would be nice to be able to 'draw' a lake or wooded area directly in the scene designer and tweak its properties directly. * True 3D grass for covering a terrain (not replicating and scattering the 'patch of grass'). This looks really good in WB (IMHO). You can obviously get close with procedural textures, but the difference gets clearer the tighter your shot is to a grassy area. Considering packages like Poser and Carrara are coming out with support for 'fur' and other similar strand-based textures, this should be part of a landscape generator these days. * A wind model that can consitently influence plant models, waves, clouds, etc. Very key to realism when you move from stills to animation. * Weather effects like snow, rain, animated fog (would be great if influenced by a wind system). This could be real unique feature if done well, because it doesn't exist in any other package, save for plug-ins for After Effects and high-end 3D modelers. * Improve water and wave dynamics and their interaction with other objects. Real collision detection between objects and water surfaces, resulting in dynamic ripples, foam, wakes, etc. would be another feature that would put them solidly out in front of other packages. * I like the other suggestions above about better light management and a more robust object management scheme. I probably haven't done detailed enough work to encounter these issues yet :-) * In general, I'd like to see them concentrate on landscape generation and animation issues, rather than beefing up model libraries and modeling functions. I like the fact that there's a lot of flexibility in the package, but at least IMO, its not intended to be a competitor with Animation Master, Cinema 4D, etc, but with World Builder and Bryce.
