I too, agree. You should rethink your strategy.
Make a node, put two of these in a + fashion facing away from the gun (or billboard one), then one of these with its normal alligned along the gun barrel. Then just attach it for a few frames, maybe decrease it in size each frame slightly.
I mostly find that it looks good without the star one as well if you have a strong bloom filter
Or just have only the star billboard itself and flash that. Iirc that’s how it worked in GTA SA.
