in 2.6 we got a lot more features for baking and making different type of maps
and did not find a lot of doc on these new features!
so just trying to better understand what these new features are and how to use these !
in first cgcookie video
the first map he does is by using the Vertex paint and then click on the dirt vertex
which i guess is the making of a cavity map
and not certain here if he used the bake button to do this cavity map ?
but how does this work ?
what does it have to do with dirt verts and the vert paint
and another thing if you use Vert does it means it is using Vcol feature may be?
i tought you could not mix Vcol color with other texture type like normal proc texture or may be UV mapping !
like normally UV map will overide any proced texture
but not certain about this Vcol and Vert painting!
is there a hierachie description of color mapping which can show the priority between UV proc text and Vertex paint ect…
like if you use vertex paint you cannot use any proc text or UV mapping may be!
normally the diffuse map use a simple color image which is added as a texture image = texture channel UV
you can make from the 3D highr res model a normal map and bake it then use it on the low res model
but here you must have 2 model s one high res and one low res to do the baking !
this normal map will fake any 3D features on the low res model
then you can add other texture map to affect the color spec or even mirror map to the model
i remember seeing in the UV wiki page that for skin you could have up to 7 layers of textures!
