Some Particle System features aren't supported / unclear right now

🌵 Needle Engine

Hey so there are a lot of issues with particles, some may be bugs, some are not implemented yet, i’d like to point out a couple:

  1. Size over lifetime doesn’t work
  2. Noise looks different in Unity and build
  3. Sometimes regular size (random between 2) doesnt work
  4. Circle shape radius thickness doesn’t work
  5. Orbital velocity in velocity over time doesn’t work
  6. Spritesheet animation doesn’t work

also… looks like there may be a limit of particles at once?

Hey @Thomukas1 could you provide a scene with your particle system for testing? You can send it using the Needle Engine/Report a Bug menu item and allow it to upload to our backend

  1. should work
  2. it is expected (to not look exactly the same), i would have to see that
  3. not sure what that means
  4. That’s when you’re using a custom / non standard shader right? Custom shaders are not supported for particles
  5. not implemented
  6. should work

Limit: should be determined by the max count you set in Unity. How many particles do you have / want?

for noise, my wind particles look like lightning particles xd

its a very soft noise but is much stronger in build

Could also be that some configuration in the unity system is not yet implemented. Particles have a million options and combinations

It would be easiest if you could send a repo - then we can have a look and see whats the issue

Thank you! Should be just clicking the report a bug button, it bundles what is used in the current scene and upload it to our server (encrypted)
