There are two main paths to making Ages for Uru: Blender+Pyprp and 3dsmax+Cyan's Plugin.
(I recommend using 3dsmax + Cyan's Plugin, but Blender is free, and it can be difficult to find a legal copy of 3dsmax v7.)
3dsmax + Cyan's Plugin
- 3dsmax/Getting Started
- 3dsmax/Dustin's Quick Tutorial
- 3dsmax/Dustin's 3dsmax Cookbook

Blender + Pyprp
- guildofwriters.com's wiki: http://www.guildofwriters.com/wiki/Main_Page
- Andy's tutorials: Andy's Blender Tutorials
- Dustin's Old Tutorials These may be outdated, but I'll put them here anyway.
