Chris writes "The long-awaited follow-up to the "photorealistic scenery generator software" Terragen, Terragen 2, is making its first public release since going into development a few years ago. According to creator Matt Fairclough's website, this Technology Preview is based on the high-end edition of the full program — the release date of which has not been announced — and utilizes most of its features. It has been suggested, however, that the node-based system might scare off the less savvy users and, as such, the release is geared towards the high-end users. There are two versions of the Technology Preview: one for Windows 2000 and XP (no word on whether it will work with Vista) and one for Macintosh OSX 10.4. As of the time of this writing, the site is severely slow and there seems to be an error with the mirror script Planetside is using, but some members on the Terragen message board are announcing their success in downloading the client."
