It looks like targetStopDuration isn’t working properly for GPU particles. After stop duration active particles keep “floating” around, instead of being disabled. There is also some possibly related issue with re-starting the system, which doesn’t seem to work unless doing something like ps["_act…

Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes I added the hemispheric emitter by code and it also breaks the PS… I exported bith GPU PSs to JSON (w and w/o hemispheric emitter), compared them and there is really…

Let me add @Deltakosh the particles daddy to the party as I bet he ll find it in less time I need to write this :slight_smile: Please bear with him, as he is in vacations until next week.

Thanks, lemme know if there is anything I can do to help. And what a cool title: “Particle Daddy” :smile:

Another particle related question: how do I set particle rotation so it matches their velocity, i.e. the direction they are emitted or “flying” at?

Please, start a new thread for new questions so that we can keep this one for the bug, thanks :slight_smile:

ok help me reconnect with that thread :slight_smile: What is the problem highlighted by your PG? (I must be slow, I caught COVID ;))

With the default cone emitter everything is fine, targetStopDuration works as expected. However with e.g. a Hemisphere emitter, it looks like at targetStopDuration no more particles are emitted, but existing active particles are “frozen” and do no longer live out their lifecycle

I have the same problem, when I change from CPU to GPU particle system - targetStopDuration not working. (defn explode [emitter] (let [ps (create-particle-system {:name "explode" :gpu? true :particle-texture (api.asset/get-as…

Sure: Orient particles along their velocity
