stonemason; Getting back to your question, the learning curve in Infinite is throroughly dependant on just how far you intend to push. The interface is pretty straightforward, and the manual is thick enough to qualify as a lethal weapon. The layered output is pretty self explanatory, as is the basic terrain editor, and older material manager. The complexity starts to ramp up a bit when you get into animation; Vue in general and Infinite in particular makes extensive use of time spline graph functions, for instance. The node based material editor has a learning curve I can't comment on, as I haven't gotten into that one yet (more due to time lack than fear of complexity), but the material blending is one of the key tricks in creating complex ecosystems. Ecosystems in itself is easy; and most of the tricks used to date are even easier (like using black and white images to create areas where the ecosystem -doesn't- place items...creating roads, patterns, whathaveyou). And oh, that multi wave fighter flyby was an ecosystem as well, with the base geometry set to invisible. The network rendering is almost obscenely easy to set up (and Infinite comes with Mover 5 integrated, so the only added packages for sale at this time are RenderCow add-ons. You get 5 nodes with the package, and the add-ons come in 5 and 25 node lumps. And there is no apparent upper ceiling to the number you can have). And it works very well. Both Vue4Pro and Infinite allow you to mix Mac and PC clients on the same network, so you have more options there. Oh. You -do- still have to buy the liscences for the extra vegetation available at E-on. The actual plants are in the add-on folder on the install CD, but need a liscence number to be useable. There are teething problems with the P6 import at the moment, but over all it works very well (I did set my P6 to -not- use external morphs, and decompressed the whole magilla, to keep things compatible content-wise), and E-on is pretty aggressive in the service update department. (some bitch about the number of patches, but I'd much rather deal with a lot of patchs than not enough). In a nutshell, you can get a good meal straight out of the box with a few mouse clicks and no experience. But the banquet awaits for when you probe below the surface...
