Hi. I really can't get the understanding of whole concept, and therefore its implementation within Godot. Can you correct my guess-work.
First, I assign a plane with material consisted of drawn red texture (32x32 for example).
Then I pick the direction, or just make it burst after editing and set to "shoot once".
I then need these particles to collide with almost all the surroundings, so that mean I'll have to use GPU particles with GPU particles collider. Even if I managed to achieve that, lying particles will not work, there had to be decal applied on to the surface where the each particle collided.
And this, is the part where I'd like ask more about decals without current context, but it seems I can't find anything like decal in the nodes list at all. That also means I'm stuck with implementation of bullet holes, some extra details like posters and junk etc.
Any assistance please?
