Hi, i have a question to ask here...i saw on the tutorial on xsi - the next generation game, and i'm confuse at some part. Well, after generating the normal map and ambient occlusion map, then you apply the constant shader to the character, then the normal map will not apply to the character right? Then by the way, can i just create preview of mental ray then replaced the AO file with the color map? Thanks. By the way, i not really understand why you need to delete the tangent property. well, will it affect other thing after you delete it as before that we use the tangento build the map.
