Custom Render Textures are a special type of texture that allow you to update a texture with a shader. They are an extension to Render TexturesA special type of Texture that is created and updated at runtime. To use them, first create a new Render Texture and designate one of your Cameras to render into it. Then you can use the Render Texture in a Material just like a regular Texture. More info
See in Glossary. You can use Custom Render Textures to create complex simulations like caustics, ripple simulation for rain effects, and liquid splatters.
The Custom Render Textures feature provides a scripting and Shader framework to help with complicated configuration like varying update frequency, partial or multi-pass updates.
To use this framework you need to assign a Material to the Custom Render Texture asset. Custom Render Textures require a compatible Material. For more information, see Writing a shader for a Custom Render Texture.
Important: The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
For more information on migration, refer to Migrating from the Built-In Render Pipeline to the Universal Render Pipeline and Render pipeline feature comparison.
The following table describes the compatibility between the Custom Render Textures feature and each render pipeline:
| Feature | Universal Render Pipeline (URP) | High Definition Render Pipeline (HDRP) | Custom Scriptable Render Pipeline (SRP) | Built-in Render Pipeline |
|---|---|---|---|---|
| Custom Render Textures | Yes (1) | Yes (1) | Yes (1) | Yes (1) |
