Tyres

Tyres need 2 textures, one for the tread and one for the sidewall.

Blur and wear and wet version of the tread

• Create a text file with the same name of the tread texture and extension TXT, in the folder where the tread texture is located
• Fill it with the filenames of the 23 additional textures for all the wet, wear and blur combinations. Example ( but filenames can change ):

tread_b1.tga
tread_b2.tga
tread_w1.tga
tread_w1_b1.tga
tread_w1_b2.tga
tread_w2.tga
tread_w2_b1.tga
tread_w2_b2.tga
tread_w3.tga
tread_w3_b1.tga
tread_w3_b2.tga
tread_wet.tga
tread_wet_b1.tga
tread_wet_b2.tga
tread_wet_w1.tga
tread_wet_w1_b1.tga
tread_wet_w1_b2.tga
tread_wet_w2.tga
tread_wet_w2_b1.tga
tread_wet_w2_b2.tga
tread_wet_w3.tga
tread_wet_w3_b1.tga
tread_wet_w3_b2.tga

• Supported formats are TGA and BMP
• Make sure that all textures exist in the same folder of the base texture, and that they have the same size

Dirt Layers

• Create a text file named tread.lyr in the folder where the tread texture is located
• Fill it with the filenames of the textures for all the marbles, grass and sand dirt and blur combinations:

numlayers=3
layer1
{
numframes = 6
map=nobase_marbles.tga
frame0=marbles1.tga
frame1=marbles1_b1.tga
frame2=marbles1_b2.tga
frame3=marbles2.tga
frame4=marbles2_b1.tga
frame5=marbles2_b2.tga
}
layer2
{
numframes = 6
frame0=grass1.tga
frame1=grass1_b1.tga
frame2=grass1_b2.tga
frame3=grass2.tga
frame4=grass2_b1.tga
frame5=grass2_b2.tga
}
layer3
{
numframes = 6
frame0=sand1.tga
frame1=sand1_b1.tga
frame2=sand1_b2.tga
frame3=sand2.tga
frame4=sand2_b1.tga
frame5=sand2_b2.tga
}

• Please note that "nobase_marbles.tga" is just a workaround to be able to load the shader file nobase_marbles.shd; the "nobase_" prefix is used to skip the texture. If not skipped, the map will be always drawn on the tread.

Integration

• Export the EDF files of the tyres
