Hi All:
I've resumed my mesh_camera experiments, this time trying to bake two
kind of dirt maps. One is a classical AO map, using radiosity from a
white sphere, and the other is a sort of "dust" map using a slope y
pattern. Here are attached some examples of their typical usage back
into the original mesh...

Thanks for the compliments, guys, but that actually was a very cheap
and simplistic AO simulation, which was missing most of the fine
detail... this one is much better IMO, as it resembles more what other
programs (blender, wings3d) obtain for this same mesh. The trick this
time was to discard radiosity and use a box-like formation of area
lights (24) with insane area size.

Wow! This is indeed stunning. I particularly like the iron version. This
goes far beyond any proximity pattern coding I believe.

Brilliant stuff. I especially like the ceramic with the brick floor.
I'll have to have a play with this technique (someday!)

Well, at least is faster and can be reused with no cost, but it only
works for uv-mapped meshes...

Right. That would not be a problem for me. Does the AO map correspond to
the uv maps? That looks quite complex.

The baking step is really easy to setup, and then using it back into a
regular scene is also easy, either trough layers or texture maps. I will
upload an example to p.b.scene-files later this week...
