The first big speed bump was, we got Vegas all together, we got it all procedurally textured, and we looked at it and it didn’t look real. The only question in my mind was, ‘Well, how do I convince my director and my producers that we’ve done everything we can to make it real?’ The only way to do that was to be able to do a side by side comparison between something that was real, out of that material, and what we were rendering.
