Render to Texture - at least in Max 6 is not optimised. This means that models with the skin shown 4 times (say on the four walls around a room) comes up as 4 separate images (I recognise that this is because they could be effected by lighting). This means that the quality of the maps is not high. Realisically for game design I would want a render to texture which incorporated tiling of the textures and ignored lighting effects.

Static.
