Blender import/export types

This is a 100% complete list of built-in Blender import and export file types/formats as of 2.49b (some file types/formats 2.5 support aren't listed here, but most are). More file types (such as Valve's .smd) can be supported with Python scripts. For importers, do a google search for "Blender [filetype] import" where "[filetype]" is the file extension you wish to import, minus the period. For exporters, do a google search for "Blender [filetype] export" where "[filetype]" is the file extension you wish to export, minus the period. For example, if you're looking for an .smd exporter, google "Blender smd export"

Unless otherwise noted, import and export requires the python version that your version of Blender uses. Blender 2.49a for example requires Python 2.5, while Blender 2.49b requires Python 2.6 . When Blender loads up, the console window will say something to the effect of "Compiled with Python version #.#.#", where each "#" is a number. The last number can be disregarded, but that is the version of Python you need. For example, Blender 2.49b lists 2.6.2, however 2.6.6 works just as well. The higher the third number, the better. Go to >> http://python.org/download/releases/ << to view a comprehensive list of all Python versions.

NOTE: Some of the below entries are missing spaces or have an extra space between the file description and the extension. This is not a typo, and is found exactly the same way in Blender 2.49b . This shouldn't affect Google searches for this list however, since Google looks for matches both containing a space or lacking one where provided in the search string (unless "quotes" are used, which makes Google ignore a lack of spaces)
