Making new graphics

I would like to maybe help make some new graphics for OpenTTD.

I have searched the forums and what have you but I can't seem to find any basic newbie information on how to get started. I have downloaded blender though.

I think I learn best when I take a finished product or graphic in this case, and learn how to manipulate it from there. Reverse engineering perhaps.

I see there are .grf files in the data directory but how do you "extract" those graphics from them?

Sorry if I am missing the point of how openttd works.

Cheers

A slightly longer response.

Much graphics development happens at TTDpatch (http://www.tt-forums.net/viewforum.php?f=54).
The reason is that both projects use a common file format called NewGRF for the graphics, and TTDpatch was the first project using (and also developing) that format. There are also more wizards in NFO (the language to make NewGRF files) and grfcodec (the tool that converts .nfo -> .grf and also the other way around).

The common graphics file format means that the NewGRF files can be used both by the OpenTTD project and by the TTDpatch project. There are differences in supported primitives however, see the OpenTTD wiki pages (somewhere at http://wiki.openttd.org/index.php/Graphics_Development) for more information.

I started to work with Blender, too... I already did some tutorials to learn the basics, however, as my aim is to be able to draw graphics for ottd, i would LOVE to have an example .blend file for studying... If someone got one from a (more or less) simple house as an example and could upload this that would be very cool!

Timitry: I'm sure there are many around, but a good place to start would be > here <, as there is quite a lot of different buildings in blender. There are more in some of dmh_mac's later posts also.

Hey,

Have you guys decided what kind of licence you'd like to use for the blender graphics yet?

If you have please post here or pm me, so I can release the blendfiles you linked to under that licence.
