Blender 2.80 Beta May 27 build Collision help(edited)

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

jjesse94 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.

jjesse94 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

jjesse94 I mean really scale it down, your collider is still kilometers large.

jjesse94 This is what I get with your file after scaling everything down:
