I'm rendering a staff with a transparent diamond prism, and everything was working fine until I noticed, while animating, that the crystal was suddenly displaying its texture as though it were opaque.
When I examined the object in edit mode, I noticed that it was invisible. Attempting to select all vertices with "a" and using "alt+h" to see if they were hidden in edit mode did not solve the problem
I checked the texture the crystal is bound to just to make sure that it was transparent.
What would cause the object to be invisible in edit mode? And why wouldn't it display with its proper opacity?
