Can you help me? i need to know, how i do.

Thanks.

easy
for example copypaste an carbonfibre pattern, then select the whole image of it, and select form a brush and you'r done

dwnload or create the cf textures (i have many of cf texture, but i never try to create myself)

then transform >> warp, then bend it as the area u want to apply that, then "ok"

but i'm confused, many tuts in google always said u must doing twirl (filter >> distort >> twirl), then apply it..
