Culling rain particles when inside a building?

JoshVanZuylen

Hey!

I currently have a particle system attached to the player that spawns planes with a rain texture on them.
The player can walk into buildings inside the level I created..... And it rains inside, no suprise there!

I was wondering If there was a way to cull the particle system with a volume or something else?


Thanks guys!

you can disable the particle system in kismet using a "toggle" node. all you need is the toggle and a trigger

Because of my situation I need a box shaped trigger, so I am using a trigger volume. The problem is that after it has turned the rain off it does not turn it back on again. Like its not detecting the player has left the volume.

In the Kismet, in the TriggerVolume_Touch, you go in its properties, and you set 'Max Trigger Count' to 0.

By default it is set to 1. So when you enter the trigger, it count as 1 trigger > Disable your rain, but when you go out it will not toggle your particle again because it has triggered his max count: 1.
Setting it to zero will just disable the trigger max count.

You can set particle meshes to "die" on collision. Just make sure you spawn the water particles high enough so that they'll collide with the roof. I've previously done rain where a single rain drop is a single mesh. It worked quite fine.

I am planning to make some rain too, but not an intense rain, a really light one.

I was planning to kill the particles on collision like you suggested Xendance, but I want to make long particles (Like in here: http://24.media.tumblr.com/d711070f088552607e9f4547f62ddb39/tumblr_mijesgBQlZ1s6o4nio1_1280.jpg ), if I kill them, they will dissapear completely, including the long trail.

SO I was wondering has anyone used animtrails or ribbons to create a rain particle effect ?

Oh my goodness. Rooky mistake! Will test at work today :$. I'm spawning planes with a scrolling texture. (They don't move) do I can't really make them die on collision.

Thanks guys!

Thanks guys! It no longer rains inside!
