Editable ! Alpha fade in / out by touch it. w/steps timer

just what I wanted. A textured object to alpha. Perfect for items like windows that are linked to the main build, edit linked parts after and it won't affect the whole build. No worry with can I or can't I add texture to contents of an object, just texture as normal then use this to alpha on touch. It is a soft transition too, no sharp snap to it. Simple and useful. Thankyou
