Reza Sarkamari walks through extracting Object IDs in Unreal Engine and working with ID and Cryptomattes.

This new Unreal Engine tutorial from Reza Sarkamari covers working with Object IDs and how to extract ID mattes from Unreal.

Reza shares practical rendering tips and, most notably, shows how to get the most out of these kinds of matte in Unreal and Nuke by harnessing the capabilities of cryptomattes.

This technique is a great way to mask specific areas in your scene, whether for color correction or the isolation of elements, such as sky replacement.
