This will cover the General Usability of the Texture Tools Plugin.
The Texture Tools UI is presented with a main Toolbar along the top with a selection of tools and a window beneath the toolbar which will display the current selected tool.
To Input a texture select the texture asset within the content browser and then press the "### Input" Buttons displayed as large colored boxes. This will input the texture data into the selected Tool.
To remove the current texture asset from the selected tool, right mouse click on the "### INPUT" button.
Each tool will have its own Output Settings. Once a Texture has been input, it will default to its original texture settings. All of the settings are the same as what you would find in the default Texture Editor.
