## Definition

### Remarks

You can use /initialize()/ to reset a Custom Render Texture or to execute two passes after each other, where one occurs in /initialize()/ and the other in  /[CustomRenderTexture.Update](/engine/6000.0/script-reference/unityengine/customrendertexture/update.md)/. When you call /initialize ()/, Unity uses the settings the Custom Render Texture has when Unity renders it. This means if you call /intialize()/ more than once when you have changed settings between calls, Unity runs the initialize render multiple times with the last settings you applied.
