1.) Is it possible to UV map an alpha transparency? Like suppose I made a cutout image in Photoshop with a transparent background, and then I UV mapped it to just a plane in Blender. I want just the cutout to show up, not the rest of the plane, so how do you set Blender UV maps to keep the transparency?
2.) Whenever I do UV mapping, the UV maps always seem to be turning out jaggy, even if the surface is just a plane. On the contrary, I’d actually like to render images that could be of print quality, so I need something highly refined even at around 300 dpi. The thing I dont understand is what “Blender Units” are - they dont seem like pixels per inch, or anything I’ve seen before. Anyway, when you are UV mapping an image - how do you:
2.a.) In Blender, identify the number of pixels in your face? This would allow me to at least predict the layout image quality in Photoshop beforehand, but he numeric transform doesnt seem helpful, unless I’m missing something.
2.b.) In Photoshop, create the best resolutions possible for UV mapping?
