Yeah I did quite a few of the engine shots, but it never occured to me to try the interior shot til I saw it on the other forum. But I didn't like the way the guy did it, he had the interior be as sharp and clear as the exterior of the car so it looked kind of weird. (I'll try to make another one like he had it so it makes more sense)
I thought it would be sweet to still have the door, trim, window, all that good stuff be visible and have the interior be just clear enough to make stuff out
