Thanks for that Polax, I have a copy of Vue 4, but am looking at getting Vue 4 Pro, or Vue 5 Infinite if it's released early in January. How well does it handle hundreds of trees? I opened a standard tree (fir) and created 300 copies, and it coped well, but the landscape seemed quite barren still - and with a terrain it was 4.2million polys. I'm not sure if it would handle much more! Not sure if Vue is good for dense forestry...
