View Full Version : Baking AO from hipoly to lopoly?
Sastrei 04-30-2007, 06:33 PM Hi all,
Just curious, can Blender render an ambient occlusion pass from a high poly mesh to a low poly mesh?
Something akin to the 4th diagram down, showing the normal and ambient maps side by side.

I believe it's planned for next release, Tangent Normal Baking that is:

The AO map can be done, even now. But the Tangent Normal map will come soon (next release, or two).
Though a hires AO map may look a little strange on some meshes without a corresponding normal map. And keep in mind that Blender can use normal maps, just not create them currently.

It's for a game engine that doesn't support normals (HW2), which is why I was just looking at the AO bake, since it's the next best thing.
Hm, so best bet right now is just to create a greeble pack seperate as shown in that tut above and cut n paste those as a start to textures, or map the low poly and duplicate that and then subsurf and modify and hi-poly-ize that one?
