Particles in 0,0,0 in particlesGpu due to negative life

ParticlesGPU v2.2.10, TD2023.11600; Mac M1 (but remember this on my Win machine too)

As the title says, I am seeing some green particles in ParticlesGpu and identified the cause to be negative life values, as putting a Limit TOP with Alpha channel mask between 0 and 1 solves the issue. Didn’t go deeper into the root cause, not doing anything funky to cause negative life

Hi @function.store

Could you share where to put the Limit TOP? Is it inside the PGPU component or outside, after the chopTO? Thanks!

hey @joellecharlotte , put a Limit TOP after renderselect5, Limit min/max: Clamp, 0, 1; and make sure you go to the Common page and set the mask so it only affects the alpha:

Hi @function.store,

I still can’t make that happen. The renderselect5 is part of the color calculation and only alpha is effected by the lifetime. Do you have a reproducible example I could check?

cheers
