CPU-Particle collision stops working in fullscreen

Hi,
right now I deal with a strange behaviour in the Editor. (See Video attached) If I hit “play in selected viewport” the collision of my partricle works as expected. After switching to fullscreen (F11) the particles fly straight throuh the door. Does anyone got an explaination for this? Mhhh

Thx for any suggestion!

Hi nick0815,

I’m not seeing the same on my end with a simple newly created particle system and full screen.

In my example I am using a newly created Particle System with the following settings changed:

  • Spawn: Changed Rate to 50
  • Lifetime: Changed Min/Max to 10
  • Added Collision Module: Damping Factor set Distribution Vector Constant to 0.5
  • Collision Module: Max Collision changed min/max to 2.0 and 3.0.

Give this a shot and let me know if this is working. If it’s just your particle system that is doing this I’ll need the following:

  • A detailed setup for the particle system to replicate the issue. (or a simple project that can repro this works as well).
  • If you can reproduce using my settings above for a basic particle in your project, try using a new blank project and see if the issue still occurs.

Thank you!

Hi!
Thanks for the reply!

I think I got the issu circled! If I disable the Light-Module in the emitter everything is working as expected. Now the particles won’t emmit light, but its ok for me. But maybe you wanna try with your setup if it shows the same behaviour!

btw: If I enable the light-module and switch to fullscreen the fps drops from 60 to about 20… this is also not happening if I disable it!

Still not seeing the same when adding a light module for the collision issue. :confused:

As for performance loss I would expect some type of hit depending on the number of particles being spawned because it will be movable lights being spawned. In my example I see a significant FPS loss because I’ve got a good number of particles spawning.

For now I’ll mark this as resolved since I’m not able to reproduce. Should this be an issue please provide the full setup for the Particle System or a simple test project and I can take it from there to investigate.

Thank you!

Ok. Thanks again! Its all good for the moment :wink:

Actually I think you may have added the image after I saw your comment before that. I hadn’t refreshed the page. I’ll give these specific settings a try and see what I get. Thanks!
