I created a simple particle system with light and added collision module. In viewport collision works good but once i start game particles doesnt collide with anything.
Hi Satheesh,
This issue appears to be distance related. I experienced problem you are describing when player-camera was moderately far away from particles, but it worked properly as I came closer.
There is a setting on the Collision module in Cascade called Max Collision Distance, increasing this value should fix issue for you. Let us know your results.
Cheers!
Works like a charm!. Thanks Stephen. 
Hi Satheesh,
I am not experiencing a problem with this in a basic project. I used default particle, extended its max lifetime, and added a Collision node.
In level I aimed particle at a StaticMesh with collision, and did Play in Editor. particles did not pass through mesh.
Can you please provide more information for setup you are using? Also, make sure that mesh you are colliding with has collision.
Cheers!
Thats weird…My particles doesnt collide in-game but collides in editor. Did you add a light module? Because i have one.
I have attached particles i this post just in case if you want to check.[link text][1]
In Editor:
In Game: (They fell through floor)
I’m seeing pretty much same thing still. Works in editor, doesn’t when game is running.
