I would like to use GIMP to skin cars. There is no DDS functionality installed with GIMP, but I have found a plugin that allows viewing, creating, editing and saving DDS files on GIMP:
http://code.google.com/p/gimp-dds/
I've tried experimenting with it, but with little success in terms of the DDS formatting options. I can't seem to figure out which ones to use.
There are three sets of options available when I try to export a file to DDS using this plugin:
For "Compression", there is "BC1 / DX1", "BC2 / DX3", "BC3 / DX5", "BC3nm / DX5nm", "BC4 / ATI1 (3Dc+)", "BC5 / ATI2 (3Dc)", "RXGB (DX5)", "Alpha Exponent (DX5)", "YCoCg (DX5)", and "YCoCg scaled (DX5)".
For "Format", there is "RGB8", "RGBA8", "BGR8", "ABGR8", "R5G6B5", "RGBA4", "RGB5A1", "RGB10A2", "R3G3B2", "A8", "L8", "L8A8", "AExp", and "YCoCg".
The plugin asks you whether or not you want to generate a minimap. If you select generate, it asks you whether you want "Default", "Nearest", "Box", "Bilinear", "Bicubic", or "Lanczos".
Could someone tell me whether, based on these options, editing skins for F1 2012 is possible, and if it is, which options I should use?
