The VFX data is static, when you create a branch you didn’t create new instance of VFX objects. So a change in one branch will effect other branches.
I’ll add VFX/pSystem clone node in the next update.
Oh, that was an issue I noticed too.But here the problem is different, these are three screenshots of the same two nodes. You can see that after I connect and then disconnect velocity, the effect from velocity stays applied.
