I try baking foliage to a flat surface as seen in a 3D Max tutorial.
However, parts are just missing on the bake.
Is it even possible to bake geometry to a flat surface? I tried all options, like a cage, moving the bake target around (in front of the object, behind, in centre) etc.
I need to bake because I need other channels too, like normals, AO etc. Otherwise I could just render it.
UPDATE: I think I got closer to the actual problem - see 3rd image please. Its the normals facing the camera directly, become black. That may not even be an error, still I don't really know how to compensate for that.
ANOTHER UPDATE: After doing some research I found out that the black parts in the 3rd image are indeed no error - Normals go on the red, green and blue channel from -1 to 1. On a regular image values below 0 are displayed as black. Still I don't have no clue why those values are just cut-out of all baked maps - a normal bake should contain the negative values and it should work correctly when used as normal map. Furthermore a diffuse bake shouldn't be affected at all.
I guess this is a bug - and a waist of a day.
