Applying a Decal in Blender 2.5 Alpha 1
I had a question yesterday about adding a decal to a mesh for my project, and David Ward came to my rescue by recording this excellent little tutorial on UV mapping an image onto a Suzanne in Blender 2.51!

thanks!
I was wondering why the UV layers never seemed to work for me, didn’t realize you needed to set them as textures
David, first I’ll say you have my respect, your alien tutorials helped me improve, as well as Johnny Blender. I have watched them all.
I have to criticize this method for decaling though. If you project from view, the curvature of the surface is not considered, if you were applying a tattoo across a chest or arm, it would not “flow” across the curved surface, it would only look good from the angle you projected (not even that because it would not be warped by the curved surface).
The correct way to do this is to add an empty, map the texture to “object”, set the object field to your empty, then position and scale your empty accordingly to achieve the desired result. with this method you are assured good results.
@3dementia: Hey dude, awesome! Thanks for the tip. I may give that a shot. Cheers!
@3dementia: i disagree; here’s an example of multiple angles, using the same method to apply another “decal” to the face. notice it does indeed curve around the mesh, and still looks fine from other angles than the projected one.

also, the technique you mentioned about the texture “object” would only work with still objects; if you had a character with a tattoo, it would be very difficult to get the object to move along exactly where it’s suppose to be as you animated the character
This tutorial is about a day early :) There is a FAR easier method now in SVN.

@David: Ah, good point. Thanks, David!
@LetterRip: Whoa, awesome, dude! I’ll have to check it out soon!
Cool. But Campbell has made this way easier.

It is stretching around… sorry spoke too soon. Looks like both methods are trumped anyway though! Keep up the great work David!
‘Piece of cake’? I think not!
You have a great voice, very nice and relaxed tutorial!
too much,too less.
Good hard efort for the 3d,
but bad workflow for the simple things.
Complex for the thenical look,
easy for the result to get done.
very nice.
