What we want to do is we want to make sure also to have this file be as efficient as possible. We can control the image compression of the images that are embedded in our Substance Archive, and by default, everything's set up to be sort of a raw uncompressed image format, which you may want for a specific reason, but it makes the archive sizes considerably larger, so we can also use a JPEG compression, and for things like our ambient occlusion and curvature and everything we're dealing…
