Topic: Technical Shading In Unreal

In this video we take a step back from Raymarching SDFs and start taking a look at how we can load a texture mask and Raymarch it into Slices in Depth giving a 3D illusion.

This video covers how to load texture objects into a custom node with HLSL and how to sample values (pixel lumiance/brightness) of that texture.

Technical Overview:
- Raystep is our View Direction.
- With each for loop iteration we are adding a small distance in our view direction to the uv.
- This is stepping our sampling point along the view direction and then sampling the texture again with the updated uv's.

This results in the illusion of slices of this texture in depth.
