I do appreciate the help thus far. It feels like my approach is technically correct, but there are mysteriously unchecked boxes in the Blender interface. Indeed, after clicking on ‘Use Nodes’, and quietly wondering, “Why was I allowed to configure every single material using nodes, but then having the rug pulled from beneath me by not being able to use them?”, I found that after saving and re-starting Blender, the desired changes took hold more permanently.
I’m attempting high-resolution graphics for printing, and I only recently discovered that I could manually input my resolution to greater than 1920 x 1080, up to 10,000 x 10,000. Last night, I accidentally stumbled upon the fact that I could additionally raise the percentage scale for resolution above 100%. THAT was a feature I had not guessed at, judging by the shading on the slider bar. I haven’t dared a 1000% render, although Blender appears game to give that a go.
This image was rendered at 200% resolution, 1920 x 1080. I feel that the texture technically mapped halfway decently, but it looks inappropriate on this craft. I was aiming for a harder, glossier, reflective look on the band at the top, nose, and a few other details (my ‘chrome’ material). My render time was 1:39 for 1,000 passes at 1920 x 1080 (x200!) which should come within the ballpark of a 6.5" x 3.5" image at 600 dpi, if everything works out properly. I recognize that I’m asking for more processing time than most people, who only require 72 dpi for monitors.
As a final aside, the day cannot come soon enough that I may sit on the other side of the screen, answering the noobish questions I’ve had for far too long. Thanks, everyone!
Edit: 24 megabytes seems to be too large for the uploader to accept, perhaps? I’ll halve the resolution of the rendered image…
Edit 2: 8 megs still too much? Good God, y’all. I’ll try compressing, to ruin image quality.
I hope everything still reads correctly. I expect it will.
