Zippo

Zippo is a tool for speeding up Lighting. It lives in the Lighting Tab of the Toolbar, and has the following functions:

• small images: uses lower rez versions of texture images, speeds up viewport loading
• Simplify buttons for subsurf and child particles (same as the scene ones)
• restore local resolution in case low rez images are saved in the file.
• switching the active renderlayer
• Enable and create a simple material override for the active layer
