These are some Web sites that we have found useful for filmmaking. More added as we find them.

RonDexter.com — Extensive filmmaking tips from a professional.

Screenwriting at Wikipedia — Wonderful article describing not only the different structures for a script, but also the format that the script should be presented in if sent to a studio.

Detonation Films Free Stuff — Detonation Films sells stock explosion footage at quite reasonable prices, but they also offer lots of free explosions.

Blender — Free, open-source 3D animation software with feature set comparable to commercial software. Works on all major platforms.

Dryad — Free, collaborative, high quality tree generator, licensed for any use. Exports to Wavefront .obj files, which Blender can import.

Mayang Textures — Free textures for 3D animation. They only ask that you limit yourself to downloading 20 per day. Note that these are not seamless.

The Freesound Project — Huge, collaborative database of sound files, all licensed under the Creative Commons Sampling Plus License.
