I was playing Halo2, and there's a section where you go from one environment to the next through a little canyon, that gave me the idea. I'm assuming Bungie work with sub-division surfaces, so I wanted to see if I could come up with something. I modelled the terrain in LW9, one object with 3 material zones. I was limited by LW's point limit on exporting LW5 objects, or I would have used a denser mesh. OBJs files in Vue can't be split into material zones (I think), and 3DS files just gave me errors on export. The file itself was about 72k after 'freezing'. Applying an ecosystem to a particular material zone was tricky but I think it paid off. Anyway I got tired of trying to get the damn ecosystem to do what I want, it seems to have an arbitrary way of working. Maybe one day I'll actually get around to doing a render in LW. Hey ho. Cheers.
