I use the import images as planes addon. I get the image. But then I noticed when I use it on a 480p image, its the same size as a 1080p image. I don't understand....is it keeping the aspect ratio but displaying them as the same size.....? When I try to define my aspect ratio in the dimensions tab it blows up so large that I can't zoom out to see the actual image anymore. So I'm guessing these are 2 different things.
All I want is to display my image in the 3d viewport at the same aspect ratio as the image actually is.
I don't really understand the unit system in blender. I can make a cube 1 unit in the x direction, 1 unit in the y direction. What is this unit though? I'm used to units being pixels.
