[Bf-committers] Texture baking proposals

[Fredrik hansson]

i definitely would like to see some super sampling and more options to bake to like the specular color map and all that goodness.

got 2 more ideas to improve texture baking that wasn't on your list.
first some form of cage for baking one mesh onto another this would let you control the length of the rays and direction so you can avoid things like http://www.hula.ca/cylinder_normal.jpg or as shown in the last image on http://www.poopinmymouth.com/tutorial/normal_workflow_2.htm with the cage. 
the cage would basically be the same mesh duplicated and moved outwards in the normal direction + the ability to move verts manually.

now the second thing is in the same spirit but much simpler.
this would be to avoid areas where its easy to get rays that hit the wrong surface like between fingers by placing a blocker mesh that is just a single face between each finger that if the baking rays hit those they won't try to go any further and use the last valid hit instead.

heres some examples on a mesh of mine baked using xnormal that has support for all of this

first one with the cage has only had the bottom of the cage edited to be flat with the sole of the shoe so notice how much cleaner the bottom edge of the sole is.
second one has had a plane between the legs only so that effectivly did the same as setting a small distance value however the distance value might be ok with say 0.1 for the legs but the fingers or that cloth thats sticking up on the shoe might need much less and lowering the value might cause the foot to show up trough the side of the shoe as if that needed a larger value.
the third one is without any of those features and the max distance set way to high.
the cage might handle both of these issues but is much slower to setup as you need to go over the entire mesh instead of just adding planes where you see fit.
