⚠️ Notice: RLD Development Status

RLD is currently on hold. No new features or updates will be added to this version.

A full remake is in development with support for Unity 6, URP RenderGraph, and modern workflows.
The new version will be released as an upgrade.

Some features in this version may not function as expected in Unity 6.

⚠ Note: ⚠

- Render Graph not supported!

- the scene gizmo is not available when using URP;

What is RLD?

RLD is a suite of well crafted level design tools that will enable you to build runtime level editors, modding tools, or any type of application/game that contains level design elements.

Note: This plugin serves as a kickstarter project and API for developers who want to build their own in-game level editors. It can not be used to build levels inside the Unity Editor. If you are looking for a level design plugin that works inside the Unity Editor, you can take a look at GSpawn - Level Designer.
