Greeting all, I am new to Vue, using Vue 6 Espirit with Ecosystem and Botanica modules. Most of what I am hoping to do right now is open prairie and savanah sorts of scenes (hence the Ecosystem module). I have a modest selection of grasses now, and have gotten them more or less color tinted the way I want (more the browns than greens), and have populated ecosystems with them quite well. However, these ecosystems are, um, massive. My first convinvingly good looking attempt was over 172,000,000 polygons. I was able to adjust some plant sizes for the primary grass object and got that down to around 70,000,000 polygons, but that still takes forver to render on my system. I am currently doing the following to help economize : I have a small terrain in the foreground with an ecosystem on it, then a larger terrain behind it with a slightly sparser ecosystem on it, and then a very large terrain with a matching color texture and no ecosystem. So, with all that - is there anything else I can do to help reduce the polygon count, or somehow speed up renders? Even in Preview mode in a small window (480x360 or so) it takes 25 minutes or more to render, and a final render, even with custom settings to turn off most of the fancy stuff, takes around an hour and 15 mins or more (without the fine tuning it was going to be something like 4 hours). My system is poky, I know, for Vue, at a 1.33Ghz G4 and 1Gb of RAM, but is there anything else I can do to help me along here, older and wiser heads of the Vue world?
