The projection I mentioned is about how the LDRaw geometry is 'projected' onto the texture image itself.
PNG's don't have that step as they're already image data.
OK, that's what I guessed. I can't think of a reason this would be anything other than orthographic, but maybe there is one.
Quote:Zoom level details is usually done through mip mapping, the resolution I mentioned is about how big the 'master' image will be internally.
Looking at some official texture for mini-fig faces (which are actual quit low res) 10pix/ldu seems like a decent starting point.
A good starting point, yes. Maybe the spec needs to set a minimum resolution, but as LDraw is a vector format I would leave it open-ended, as the resolution is effectively limited only by memory I guess. Some programs probably have a practical limit already built in.
