Blender

Blender is "... the open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback. Available for all major operating systems under the GNU General Public License."

Blender is a feature-rich and full-value alternative to commercial 3D-modeling suites like 3ds Max and Maya. Due to its open source character, there are various exporters available that allow you to export your models in a format that is suitable for use in Unreal Editor or the UDK.

Import/Export Plug-ins

This list contains only Unreal-related plug-ins. Other Import/Export scripts can be found here.

Export Plug-ins

Goofos's ASE exporter

Exporter available for 2.4x and above

There is another ASE exporter for both 2.36 and 2.37a versions of Blender

(Note: script version 2.37a will work in Blender 2.37a up, so it works with 2.40 and 2.41 as well. 2.36 on the other hand, will ONLY work with Blender 2.36)

• Download from KatsBits (thanks Kat!)
• Also check the development thread for info on usage,

• Video tutorials for creating low-poly terrain objects in blender, using Goofos's ASE exporter,
• Vertex Painting but I'm not sure if Unreal makes use of,

Any further questions can be posted there or on Kat's forums.

Doc Holiday's Blender to .ASE

• http://www.neewo.de/Files/USM11Script.zip (updated to 1.1, fixed scale issues)
• A tutorial for this plugin in the context of Doom 3

Cambo's Blender to .ASE

• http://blenderartists.org/forum/showthread?t=45180
• Tutorial in German (try google translation)

NOTE: When using the export script, it will throw an error if it does not find the default .00x after the datablock name of the texture.

Optimus_P-Fat's PSK/PSA Export Script

• Download from p-fat.net

NOTES: Please read the caveats on p-fat.net before using this script. There are a few things it doesn't handle that you must do to your mesh before the export, like converting all quads to triangles. This script is still very much "alpha", but seems to work fine for meshes, armatures, and animations.

Darknet's PSK/PSA Export Script

This is basing on P-Fat's script and has some enhancements.

• Latest version available at Epic's Forum

PSK/PSA Export Script by unknown author

This shall facilitate the export of animated meshes and models to Epic's Unreal Engine's *.psk and *.psa format. Requires at least Blender 2.45 and a full Python installation.

Import Plug-ins

Goofos's ASE importer

It is written for Blender 2.42/2.43 but should also work in newer versions. The ASE import script will bring in mesh data as well as any UVWmap and vertex paint data found on the selected ASE model.

Python Scripts

Blender is open source, hence some community members wrote scripts that can help modelers by fulfilling automated tasks, for example modifying an object under certain criteria or creating a certain kind of model to start from.

Written Tutorials

Blender 3D: Noob to Pro

Great, extensive and free online book. Step-by-step guide that explains everything in detail and with pictures. Maintained by the community, following the wiki-concept. [1]

Video Tutorials

Super3boy's Blender Tutorials

Mixed collection of video tutorials. More related to creating a scene for rendering than modeling a mesh for a videogame, but nice to take a first look at how things can be done. [2]
