Like a high detail models lighting and surface data to lower detail model underneath.

channel with the Surface Baking Camera:
(this is a beta not fully tested)
kruemel_1 said:I'm settings the lowpoly object to unseen by rays and camera so it does not affect the render at all. In the Surfacebaker camera I use the lowpoly mesh and it's UV map, an then I have to set the offset high enough so it covers the whole high-poly mesh, not uncommon to set it to 10mm or more.
And the PSD export idea from chunderburger is also a very good one. I personaly need only the color and occlusion map (2 separate renders).

baking, added also a material output (may be useless)

Normal & Surface Cast get texture from one geometry,Sammael said:What does this node do diferently that LW cant do natively? ...

Normal & Surface Cast get texture from one geometry,
even if it has different UVmap, this two nodes do a ray-intersection
of the surface of the hi-res or model to catch,
along the smoothed normal of the low-res object, which
can get its value(s) for baking into its own UVmap.
Normal Cast can work in "Tangent Space" which is better
for mapping the normal of animated objects.
set your low res object to unseen by camera.
set your hi res object to unseen by rays.
add PSD export to image filters & choose diff, spec etc
dpont said:Yes I have remove it, as said Dodgy here and Duke in another thread,
you can do this directly and faster in Surface Baking Camera
and export Photoshop_PSD plugin,
except for tangent normal map which needs a transformation.
Normal Cast Node does it in the color channel, because there is
not specific buffer for normal map, so it should be baked separetly.
If you want a whole baking system, as said before, there's still the
expensive Microwave plugin, a pixel filter plugin.
