rdSplatTools is an Unreal Engine plugin that allows you to paint areas of your level with multiple layers and convert them into a tight, compressed SplatMap that resides in CPU memory.

The painted areas can have an adjustable falloff, or be just on or off.

Your game calls the rdSplatTools game subsystem when your player moves, you pass in the player location, it returns a filled in array of float values, one per painted layer – the values range between 0.0 and 1.0 giving you a soft proximity to the masked areas.

This system is very easy to use – just paint your masked areas in the Edit Mode and then save. The compressed SplatMaps are tiny, and only in CPU memory and reading them is extremely fast. Also included is a Material Collection that can optionally be automatically updated with the current values so your materials can reference them

The SplatMaps are saved as DataAssets which can be loaded and saved at will – even migrated to other projects.
