Today's Learning Unreal post is the second part of a mini-sub series about my experiences with Unreal's Render Target system. You can find the previous part on creating an in-game painting tool here.
Today, I'm showing off a tool that lets you leave a trail in the snow as you walk through it. As always, if you want to recreate this tool for yourself, you can find the original tutorial here.

The main development points of this tool were:
Using a scene capture to mask out objects on the ground
Using said mask to leave the trails on the ground
Increasing performance by only showing trails around the player
