Iknow this is a maya section but it is th section that gets the most hits/use

so i am learning compositing
i will be using mental ray for the rendering

now there are like 47 passes by default that maya MR will output (i have turned all on, i want to learn them all)
could some one help me out here

i want to know what order the composite goes in, i.e diffuse then spec and so on

also what layer/merge operation is need for each
i.e over, plus, multiply

i have attached a .txt with a list of the passes

could someone edit is into order with operations please

i know its a BIG ask but it will help me out a lot

many thanks
