Yeah and in TM its really easy to add new stuff. you get your brush or sticker in a .dds format put it in a rar-archive and add it in the folder of the editor...
there you can add everything you whant, even if nadeo dont like it (like cigerretlabels, or alkohol).
i was wondering if here in tho forums is a good programer that could source it out of trackmania somehow and convert it to lfs...
