I'm not really sure how to phrase this, and I'm a bit of a novice still, but basically I'm trying to atlas an object that uses multiple materials/textures, and I'm running into issues that degrade the quality. This is an example of just one of the materials, it is meant to be mapped to a 512x512 image.
That works fine of course, and the quality of the image is as it should be. The problem is I've created a 4096x2048 image that contains all of the objects textures and plan to map each material to the corresponding texture. The problem is when I import the image the materials want to scale themselves to that image in the uv editor like this.
I've scaled the material down on the uv editor to fit its texture, but the issue I've run into is that the quality has then gone down significantly.
What I want is to import that image, and have the material stay the same size as it was for the 512x512 image so that I can retain the quality and properly create the mapping.
