Surface trails system allows you to capture trails from characters or any other objects on a surface by attaching spherical components to them. As main usage example there is snow landscape demo with walking character and physics objects leaving deformation trails after them. 100% Blueprints.

Features: Trails are captured and stored in some area (configurable) around player’s camera, so this system is independent from map size.Attenuation of old trails can be configured (can be set to zero so the trails stay forever inside defined area around camera).Trail shape is defined by spherical components with configurable hardness. So for definition of a box, for example, you need to attach several components to it (components count depends on required accuracity, in example scene there are 8 components per box and 2 components per character foot).Actors are marked as trails receivers by applying special Tag to them.System can be used for big variety of cases (trails on water, grass crumpling, any other surface VFX) by draging one material function i
