One thing I just noticed in Photoshop is a bit odd. I put the rendered "blocky" picture over the original BMP and hid one layer and went back and forth hiding them. The images don't align right. That might be because of the distortion on the render, though. It makes me think about Bryce and how line by line is done several times; each time getting finer. It's like Poser skipped the last pass of the image.
