This command removes the active texture from the Texture view and replaces it with a neutral gray background. This makes it easier to see your UV mesh.
To display the active texture again, double-click the texture in the Material Manager. The Empty Canvas option will be disabled automatically.
This command can be used to display a UV Map as a background. This helps to better evaluate distortions on an object. See sample image (other backgrounds can also be defined).
Here you will find a list of all textures currently in RAM. Choose a texture from this list to display it in the Texture view (the texture will be activated automatically in the Material Manager).
