The Texture property of the TextureRect class in the Editor.TextureEditor namespace represents a Sandbox.Texture object that is associated with the TextureRect. This property allows you to get or set the texture that is used within the texture rectangle, which is a part of the scene rendering process.

To use the Texture property, you need to have an instance of the TextureRect class. You can then access the property to either retrieve the current texture or assign a new one. This is useful for dynamically changing the appearance of the texture rectangle in the scene.

Example usage:

TextureRect textureRect = new TextureRect();
Sandbox.Texture newTexture = new Sandbox.Texture("path/to/texture");
textureRect.Texture = newTexture; // Assign a new texture
Sandbox.Texture currentTexture = textureRect.Texture; // Retrieve the current texture
