What's the best way to conditionally enable / disable subgraphs (most performance)

Hi, so I created generic muzzle flash effect, which has three subgraphs: flash, sparks, smoke. All subgraphs are initialized by a single spawn event.

What would be the most performant way to conditionally (via exposed parameter) enable / disable execution of the particular subgraphs? For example I want to have a weapon where only sparks and smoke will be executed, no flash. On another I’d like execute flash and smoke only, no sparks.

I know that there are branching operators and I also know that branching in shaders can be expensive - so what would be the best way to do it in VFX graph?

Thanks,

S.

 

If we are talking a muzzle flash, unless you have 2 dozen of them happening simultaneously, I would be surprised if you have to worry about performance. If performance is a concern, I wonder if just object pooling the effects might make a bigger difference than optimizing the vfxgs themselves?
