Render Shadow pass for a single object Tweet

[alebronx]

Hey there!

i'm currently working on a project where i've to create multiple object that will be rearranged in post production with coding.

For this works i've to create items such as hair, sunglasses, chain in c4d and will be really helpfull to have for every single png the transparency of the shadow pass.

I'm able to render single object using Octane Tag but can't understand how to create a single shadow pass for an isolated object.

I give you a practical example, I've the hair of the model but i want the shadow above the head in the png files. tried to use shadow catcher above the Head geometry but calculate every single shadow above the head, i need only the hair shadow!

Unfortunally i can't upload nothing about this project for copiright contract
Hope to find helpfull tips.

Thanks for your adviece!

Hi,
instead of shadow catcher, have a look at the Render Layer technique:

You can use C4D Takes to obtain the different passes.
