I have a project that rely heavy on using a clear halo on a object to enhance the visibility of that fast moving target on a projector which has limited light and that in a messy background.
It need to be fast, and not blurry as it’s a target you take hard focus on.
I am on the limit of what hardware can do today so processing need to be fast as well.
in Built in Halo works perfectly.
However, if I am going to URP this seems to be the biggest issue I have.
Lensflare, Bloom, etc nothing seems to be what I seek.
I have an idea of putting a semi transparent sphere behind the target and move that so it will be behind at all times, that perhaps is the best option?
Dont know if you still need this, but for anyone who might come across this thread, you can write a simple shader that does outlining using the inverted hull technique (thus it can be applied per object and not to the entire screen), found this video as the literal first result when searching on google.
