"Do you know where they get those lo-poly models and the data for the normal maps to use on those models? High-poly models. There have been articles with screenshots showing the development of the Pinky demon that show this is how it's done."
I never said the Doom 3 engine could not render high poly models. I know for a fact that modelers at Id make high poly models (around 10000) in Maya. They then scale it down the number of polys and add the appropiate normal mapping (I dont remember the source, maybe an IGN preview). I just said that High Poly is not what the doom 3 engine is known for.
