Tutorials section

Postby die996 » Wed Nov 30, 2011 3:54 pm

I'd really like to have a tutorials section so the masters of the game can teach normal people (like me) on how to make stuff for this game. I'd really like to paint cars (I used to that on NASCAR racing 4) and to create robots

I'm no computer expert so a tutorial for "noobs" would be great for me :mrgreen:

Personally I like to do things like this in vector graphic, rather than bit map.... what you can do is export some key layers (just the wireframe if starting completely from scratch) from the gimp files and import them into inkscape.

Draw the appropriate graphics/decals etc and then export a bitmap at the required 2048x2048, and stick this as another layer withing the gimp stackup. Then (finally) enable the shadow layer and export as the completed skin 'png'.

Keeping stuff in vector, with items grouped and appropriately named would help reuse and build the number of skins we could offer.

I've been using layered .xcf files to separate the different aspects of a skin. Then I save the new creation as .rgb or .png

I want to learn Blender but have not had the time. I have no 3D graphics experience.

LOL - OK lets back up. Torcs and SD are available both in Linux (me) and M$Windoze.

In Linux the data for cars, tracks, etc. is located in /usr/share/games/torcs (or speed-dreams) directory. In Windoze the data directory is located in c:\program files\speed-dreams-(version number)\data\

If you look in the "cars" directory, you will find directories for all the car names. Inside those directories are .rgb or .png or .xcf files for the skin colouration.

As far as what mungewell was talking about, "Gimp" is a paint program for Linux. I am not sure if it is available for Windoze. I have not used "Inkscape" before. Blender is a 3d editing and animation program.

There are a few websites that deal with editing Torcs cars and tracks. Speed-dreams is similar to torcs. Try starting here: http://www.berniw.org/trb/index.php

And we're both assuming that you know that the 'skin' (graphics on the car) is handled by mapping a 2D image/bitmap (PNG or RGB format) onto the surface off the 3D model. So simply put, if you want the car to have a different paint job you can just alter the PNG file.

The different skins are selectable in game under the 'change car' menu page, the list is automatically filled by looking files with the name '<car-name>-<skin-name>.png' (and '...-preview.jpg' for the preview image). The skins can also contain different graphics for the wheels ('wheel3d-<skin-name>.png').

I should add that the gimp ('.xcf' files) contain multiple layers, including baked shadows and mapping (wireframe) templates. So if you enable the mapping layer you can see where the texture will be mapped on the body of the car.

To help my kids design some skins I converted some of the mapping layers to PDF here:
http://www.mungewell.org/Logitech_Wii_W ... plates.zip

If you don't have the source code for SD2.0, you can pick and choose the Gimp files you want via 'svn-browse':
http://sourceforge.net/apps/trac/speed- ... ars/models

Gimp is available for both Linux and Win32.

Wow! Thx Mungewell!!! I learned a few things from that!

Now I have to get to work on some compliant file naming. :)

Perhaps this forum should have tutorials thread!

I have been having problems importing the .ac files into Blender. Very little can be found on the web and I am getting very frustrated!

Can someone help? I am using Ubuntu 11.10 and Blender 2.61

@WingCommander:
i only use blender for shadowmaps (and work on windoze) but as far as i know the .ac import/export script is only in Blender 2.48/2.49.

i tried blender 2.61 too, but apparently you need an external script. i tried the script from here:
https://github.com/majic79/Blender-AC3D

i could not get it to work though but that might be due to some error on my part (or 2.61 is too new for it).
propably the flight gear forum might be a good point for information because they also use the ac format.
