Please keep providing different use cases with pictures to help us figure out how useful this would be to developers.

How many different applications of projections do you think would be a good starting point?

As many as we can get. The more different use cases, the more weight a feature will gets as we try to prioritize the list of potential features.

A quick search of possible use-cases:
Superhero games / projection of lights with logos etc.
Monster attack ranges
Displaying in-game holograms

having blood stains on objects would be awesome
you can animate it to be like fire licking on walls or tops of windows
car customization, I know jailbreak recently wanted to have the ability to put decals on your car and I think this will help with that

It seems that there are some cases where you want the projections to be live, like an actual projector or circle around a character’s feet, and there are cases when you want it projected on permanently, possibly a scuff mark on a car after it hits a guard rail or graffiti on a wall.
There also seem to be a lot of need for filtering object out of the cast, via whitelist or blacklist. You only want to character’s circle projection to be on the static geometry, and not ontop of other characters or intractable elements of the map.

Would love the ability to project messages or images on detailed walls, or countless other types of structures!
Cool Application:
Imagine displaying shows on a Complex Shaped Castle, such as the one here at Disney World.
Property suggestion:
Luminosity, with a Number Range of 0-1 (To create a cool laser glow effect!)

Its not quite the same; But the bullet hole thing was something I was interested in by too.
It annoys me when the bullet hole extends outside of the object.
so I made this; https://www.roblox.com/library/417168585/Decal-API
Its a little module that allows images to wrap around edges.
Although, it only works on single objects and only on basic parts and uses SurfaceGuis to position the images.
If you want an example of its application, My game Brutal and the Rolve game Unit 1968 uses it.

and it works at a fairly low cost;

however it has serious limitations;
Any shape thats more complex than having 90* angles is almost incompatable,
It will only work on two sides max, applying it on a corner will simply post it on one or two surfaces
due to rotated guis not being able to be culled, the top and bottom faces will not wrap in any case.
This isn’t quite what @Vorlias is after though, as it doesn’t work on terrain or curved/multiple parts.
Having a feature that allows for this would be incredible in its potential, from a gameplay and building perspective.

Bullet hole is a great example for this feature.

I’d use this for unit selection spheres projected onto the ground, blood splatter, paint splatter, bulletholes / explosion decals. These are a few that came into mind

If this becomes a thing, the automatic anti-aliasing that roblox does on images needs to be dealt with, but beyond that, I’m in support of it.
As an aside, I don’t think this being an extension of the decal object would be ideal, simply because it wouldn’t allow for as much customization compared to using GUIs, but either (or both!) would work.

I really hope this has been considered - there’s so many use cases and I can see myself using it a lot also. For me, I’d probably be using it in my game for ability targets on the ground like so:
I know the Beam effect might be coming soon, so I hope this is another one which could be as well.

Yes, I definitely support having a projection feature that allows one to project an image over terrain. There are many use cases, and the one I had in mind was showing a spell effect on the ground, or the radius of spell on the ground.

This was being considered at one time. On the RDC presentation, they showed a section of JIRA where this suggestion was openly view-able.

In case you guys haven’t seen what you can do with the Future is Bright ShadowMap mode, you can create some awesome effects such as Gobos, Shutters, and so much more.
Example of a Gobo:
The base of this has got to be super close to how a surface projection should work.
