Sticker with other than rectangular shape

[Philippe Hurbain]

How would one create a sticker (using texture mapping) with another than a rectangular shape?
Like for example the stickers that come with set 42061

The problem with the non-rectangular shape is relatively simple... it is much mode tricky if the sticker is not flat! You have indeed to first create the 3D shape of the sticker and make the image projection on it. Problem is that the non flat projection may introduce distortions in the image - or rather, the image must be a pre-distorted flat projection of the shaped sticker. In your case even the panel is flat enough, so distortion is not a real issue.

For an example, see my EV3 stickers! http://www.ldraw.org/cgi-bin/ptscan.cgi?...mindstorms
