Questions for a newbie to Composite?

Working in a linear order (Bottom Layer Top - Left to Right etc) I have a render consisting of:

Reflection
Refraction
AO
Lighting from Sun & Sky - GI
Specular
Shadows
Diffuse

What is the correct (general order) order that these these RE’s would be layered & what Blend & Comp Mode would be assigned to each (eg. shadows = multiply) etc.

Would I need to add a lighting RE as well?

Hope this is a straight enough Q?? Save me a lot of testing if someone can point me in the right order, can’t find any clear - straight forward tutes, forum posts or examples to the general practice of this process.

Funny I can’t find a general guide to this setup as this seems to be the basis of 3D comping for which to add/swap/modify RE’s to go off or build from?

Guide for recomposition are the same for photoshop, nuke, toxik, fusion, you can find lot of them.

You can use mathops or directly blend&comp (img schem06) witch will give you more controls in the same node.
Basically, if your GI ever contrain diffuse information :
(Diffuse+GI) + reflect + refract + spec (img schem04)

Shadows is a bit different, you can supress them from diffuse, but it isn’t an element in the same way as others. (img schem07)

PS : Nodes posters are black because this one on a linear exr with a vLUT.
