What is 2D/3D Paint?

2D/3D Paint is a universal tool that enables painting on both 2D and 3D objects. Whether you’re building a modern paint application or adding painting features to your project, this asset offers powerful capabilities with outstanding performance.

Getting started is simple: just add a component, and configure a few settings. With 2D/3D Paint, you can paint on various components, including MeshRenderer, SkinnedMeshRenderer, SpriteRenderer, and RawImage.

The asset is compatible with all render pipelines. It also works seamlessly with custom shaders, VR environments, and doesn’t require colliders for painting.

Why is it great?

2D/3D Paint stands out as a powerful and versatile tool for several reasons:

  • Ease of Use: Setting up painting features is straightforward—just add a prefab, attach a component, and tweak a few settings. Even with minimal effort, you can achieve professional results.
  • Broad Compatibility: The asset supports a wide range of Unity versions, rendering pipelines (Standard, URP, HDRP) and input systems: Input Manager and Input System. It’s also compatible with custom shaders and VR, offering flexibility for different project needs.
  • No Colliders Needed: Unlike many other painting tools, 2D/3D Paint doesn’t require colliders to function, simplifying your scene setup and improving performance.
  • High Performance: The asset is optimized to maintain smooth performance even in complex scenes, ensuring that your painting features work seamlessly without causing slowdowns.
  • Customizability: From brushes to shaders, nearly every aspect of the painting experience can be customized, allowing you to tailor the tool to your specific project requirements.
  • Versatility: Whether you’re painting on a 2D sprite or a 3D model, 2D/3D Paint offers robust support for a wide variety of components, making it suitable for games, apps, and creative tools alike.

What’s the best way to update 2D/3D Paint from an old version to a new one?

Before updating, it’s crucial to ensure you have a backup or commit point to roll back to if any issues arise. Once you’re ready, follow these steps:

  • Backup Your Project: Always start by creating a backup of your project or committing your changes to version control. This safety net will allow you to revert to the previous state if anything goes wrong during the update.
  • Remove the old 2D/3D Paint Folder: Delete the existing 2D/3D Paint folder from your project. This step is important because the Asset Store importer can sometimes lead to script duplication or leave old, unnecessary files behind.
  • Import the new Version: After removing the old folder, import the new version of 2D/3D Paint from the Asset Store. This clean installation ensures that no outdated files remain in your project.

Does it work everywhere?

Absolutely—2D/3D Paint is built to function flawlessly on every platform Unity supports. Whether you’re developing for mobile, desktop, or VR, this asset is optimized to deliver top-notch performance without compromising on features.

The asset’s scripts are streamlined and efficient, ensuring that you can paint on 2D and 3D objects with minimal performance overhead. That said, it’s important to remember that 2D/3D Paint works with Unity’s native systems, so performance will still depend on how you use those systems. For instance, high-end effects or complex shaders may naturally be more demanding on mobile devices, regardless of the painting features.

What makes 2D/3D Paint so appealing is its flexibility—you can push the boundaries of creativity, whether you’re crafting intricate textures or building an immersive VR painting experience. However, to get the best results, consider your project’s performance budget and make sure your designs align with your platform’s capabilities.

In short, 2D/3D Paint not only works everywhere but also empowers you to create wherever your imagination takes you.
