Not sure if it’s already possible or even theoretically possible but it would be quite cool to have a way of giving textures using opacity maps a degree of thickness for things like die cut sheet metal or room dividers with intricate detail. Using an alpha then applying a thickness material to simulate thickness would be great!
Does anyone know a renderer who has a feature like this? Shell does not the same, but you can fake a bit of depth with multiple shells/copies - and you still need the opacity map. It has to work something like using the opacity map as displacement.
