Hello BA community, pretty new user here. As such, I am not sure if this falls under ‘basics and interface’ or ‘materials and textures’, please recategorise as you see fit.
My goal is to create ‘stinger’ transitions with Blender. This is an A → B transition, where the change from scene A to scene B happens when scene A is fully ‘covered’ by the stinger content. See post #7 here for a basic example.
I have a simple stinger working in the form of a big arrow transiting a camera with ‘transparent’ set in Scene→Film properties.
What I would like to do for another transition, is use a mask (or similar) to uncover and re-cover a simple scene. The animation output would start with full transparency, progressively reveal the scene, then un-reveal it. However, using materials with transparency makes those materials transparent (naturally!); whereas I would like a material (or to achieve this in some other way) that has the effect full ‘A’ channel output when encountered.
I have searched for things like masks and ‘covered’ renders, but the ones I’ve found that might be of relevance apply to older Blender versions that have things – eg layers – removed or re-purposed.
Apologies for the imprecise terminology; I am happy to clarify or to create a mockup image sequence showing the effect I would like.
Thanks in advance
