This post is all about UV coordinates and how to use them in Sandy 3.0, although the theory applies to other engines like Papervision3D too. There’s a little bit of theory involved and some hands-on coding. About UV coordinates In simple words: UV coordinates are 2D coordinates that are mapped onto a 3D model. UV [...]
