Then did a render to texture, told max to use existing unwrap, a complete map to be rendered into the diffuse slot, size of 512, output into source and then render .. but all i get is a black map .. can anyone help ? Thanks in advance |
The way I do an AO pass in max is assign a standard shader>change its colour to white> environment to white>turn on light tracer>choose scanline as renderer>render to texture as a diffuse map>if you want higher quality change rays/sample to 500, filter size 2, bounces 1, initial sample spacing to 4x4 or 8x8 in the light tracer options. I always got better results that way rather than the MR/AO shader method. The black maps are annoying, god knows why that happens, just click the disc icon in the upper corner to save your map when rendered.
*edit* forgot to say the only light that should be in your scene is a skylight
