[jesse94]

I need help my collision is not working I tried undoing and redoing the collision and I tried applying the scale of the Collision object and I tried closing the file and reopen it please help here is a screenshot and my blind file( update to send it to pasteall.org fasterI turned down the particles)

Hi jesse, you didn’t provide  a link to your .blend file, so I can only guess…

First, you will need to apply the scale of your emitter.

Second, did you put a Physics > Collision on your collision object? It is not enough to have Collision enabled in your Particle System.

I tested the May 27th build of 2.80 and everything seems to work normally.

@spikeyxxx  sorry about that I forgot here the blend file  http://pasteall.org/blend/index.php?id=51836 I did apply the scale of the Emitter and as well as apply a Collision to the Collision object and it still don’t work

@jesse94 Well jesse, it appears to be a matter of scale( ie size). Select everything and scale it down to a reasonable size, like 1 or 2 meters. Some ‘Suzanne’s’ might still fall through, but the general behaviour will be a lot better! 

With some tweaking you’ll be able to get it perfect. (Maybe more geometry on the Collision object?)

Let me know if this helps, please.

@jesse94 As to make it more clear: it’s a physics simulation and each particle calculates the distance to the nearest vertex of the collider. If that vertex is 50 metres away, it won’t ‘see’ it. So: sometimes size does matter!

I hope this helps.

@spikeyxxx I scaled everything down and give the Collision more geometry and I even put a solidify modifier on it but it still don’t work here’s the updated blend file http://pasteall.org/blend/index.php?id=51838

@jesse94 I mean really scale it down, your collider is still kilometers large.

@jesse94 This is what I get with your file after scaling everything down:
