Bug What happens to particleID after we go over 4096 particles?

So I have this simple shader graph for my Visual Effect:





This forces all my triangles (and I work with triangles in my Visual Effect) to form a diagonal line.

It works great until I hit 4097 particles and then, as if by a queue, all triangles start to jump. And I have no idea where they jump to, but it is quite clear to me that something happens to the way you count particleId in your effects after particle count goes beyond 4096.

Please tell me how to overcome this issue as I have quite a cool effect that relies on particleID being consistent.

 

if you use strip and want to get particle Id, you must use " particleIndexInStrip" node

 

I was not using strips - just regular triangles spawned with a burst spawn.

 

What is your particle buffer capacity? Also ss of graph might help.
Do you have simple reproduction steps?

 

@Qriva I've updated my original post. The visual effect graph is super straight forward and the custom shader graph is in that post too. Just reproduce these, spawn over 4096 particles and watch the show.

 

Did you try with the shader graph only ? Maybe it's a float overflow or something to do with float precision.

 

Actually I can reproduce this and it's very weird. My guess is that there is maximum capacity for particle chunk and it has something to do with that. However it does not matter if particle is displaced by shader or just directly positioned in vfx graph based on id - it's exactly the same and particles kind of "blink". The question is why id is able to change, when I spawn particles all the time or more than the capacity it would be understandable, but when I spawn 8001 particles in one burst for capacity 8192 there should not be any problem.

Spoiler: And this...

when I pause the game and don't move mouse this is what I get

but when I cause scene window repaint by moving mouse, these particles just disappear randomly
