After fresh pull yesterday, I can confirm the issue. a) Caribbean and French Alps so far b) using regional definitions c) no - just tried out of the box > I think so.

If you had two different texture sheets and would need bare trees high up and leafy trees down in the valley, you would have to look up both of them for each tree - which is not so optimal. I think Stuart's way trades GPU memory (you have 4 times the sheet size now) against speed (just a single lookup). We may think about not doing the two winter slots as a simple noise function with white color can paint them with snow as well, but I think eventually we'd like to have nice winter images with snow piling correctly on the branches, and this is close to impossible procedurally, so I can see the advantage of the scheme here. Stuart, is it possible to pass somehow the info what trees are deciduous? I've done some testing, and I can selectively pick 'green' hue in the shader and color-rotate these pixels to autumn colors, but this is not sensitive enough to key on the difference between leaf and needle - if we had that, we could have autumn colors in addition. > Then "fall" and "windy" could be combined with particles (?) to simulate > wind blown leaves and dynamically painting the foliage part of the > texture with alpha to make leaves fall off on windy weather..? ;) Kinda > special case and maybe not worth the effort but might be quite awesome > jaw-dropper on the right moment.. ;-) Yes, let's forget about spending all the framerate for flight and do realistic vegetation - trees and grass should also move in the wind :-) (I like the idea in principle because it's just mad enough to be charming...) * Thorsten ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
