PlayDevil posted a short article on the new "imposter technique" for the game "The Grinder" and why its the only company that can pull it off.
Here's a snip:
"Can't really guarantee this is what happen, but I guess Imposter render the model and it's effect once, and then it calls this already loaded model, being necessary only to adapt lightning, saving a lot of processing power.
Why is this shameful to Capcom? High Voltage has been working with the Wii from ground zero to 65 fully shaded characters on screen in what, 2~3 years."
