⁠

In AE,

For composting top layer, blend mode: :Linear Dodge (commonly used for compositing), or Screen mode

Change the top composite layer for 32 bit per channel, tick linear working space

⁠

Set the BG video in C4D with multi-pass workflow:

(Tutotial use Octane Render, I just use C4D default)

Octane camrea setting: tick Neutral Response, Gamma 2.2

⁠

Create a Camera in C4D (render the camera viewport)

Render setting: Format EXR, 32bit channel, tick enable, save beauty (as a reference image to compare to), show passes, multilayer file

⁠

In Main tab, choose Float (Linear) in Setting (I don’t find it, maybe coz did’t set Neutral Response on Octance Camera)

⁠

Export the image sequence

Back to AE, import the sequence, apply effect: EXtractoR, click on the effect menu, will pop up the window:

⁠

Create on 8bpc box again, change to 32 bit channel and linear working space

Duplicate several layers,

Repeat the same step but apply different ExractoR channels:

⁠

Except for Diffuse Direct layer and Beauty Reference layer, change the remained layer blend as Liner Dodge:

⁠

Put the beauty layer on top, tap on and off to compare if there is much difference of the combined multi-layers, with the beauty layer
