Description

Substrate Subsurface Scattering is episode 5 of Ben Cloward's Unreal Substrate tutorial series on YouTube, focused on subsurface scattering with SSS mean free path and MPP scale on Substrate slabs. Cloward's channel specializes in Unreal material deep dives with step-by-step editor workflows.

The video demonstrates scattering on Megascans grapes assets and walks through authoring a custom SSS mask in Blender and Photoshop, then packing that mask into an ORMS texture channel for use in Substrate. Viewers see how slab parameters change translucency versus opaque PBR defaults in Unreal Engine 5.

Intermediate Unreal material artists who already use Substrate or migrated from legacy shading models will follow most closely. Basic texture authoring outside Unreal is shown but not taught from scratch.

The episode is free on YouTube with asset links typical of Cloward's Megascans-focused lessons. It fits a numbered Substrate series covering earlier slab fundamentals and later material types.

Cloward's Unreal material tutorials are widely recommended in real-time rendering communities learning Substrate and photogrammetry assets.
