I have a glass dome in my game that I need to project images on to in order to display information. My first idea was to use decals, but I now know that decals don’t work on transparent materials. I’ve seen that you can potentially bake the decal into the material, but unfortunately I need to display multiple images on to the dome, more get added, some get removed, they all move around, and they need to actually interact with the game environment, so I’m not sure if that solution is going to work. As of right now, I’m just using planes for the “decals” and moving them around the dome on a spline, but it’s very clear that they can clip out and around dome.
I’ve looked into a lot of solutions, but nothing seems to fit exactly what I need. If anybody knows how you can achieve the effect of having complex moving decals that can interact with the world on a transparent material (or at least fake it so it doesn’t look terrible), it would be greatly appreciated.
