18) Once pasted, Bodypaint3D will automatically switch into projection mode and making Transform Bitmap as current tool, which you can tell from the icon of the cursor, switching to a cross icon. From here, you can scale the snakeTattoo image with the handles, or you can change to rotate mode from the Attributes tab, and rotate using the handles. Do whatever you can, scale or rotate. When you are happy with the result, hit the Enable Projection Painting again to applied the changes and exit from projection mode.

19) When completed, you can now change the mode into Multiply to get rid of the white background. Reduce the opacity to make the tattoo blend in more with the skin texture. Also, you can select the tattoo layer and use Move Layer tool to interactively move the image around in 3D view.

20) Hope I have explained well. You can download the tutorial material here.

21) In the next lesson, I will prepare a more indepth tutorial on how to put projection texture method into good use. For now, hope you find this tutorial useful.
