Tunnel fire and smoke

[davide445]

Testing the creation of a fire situation in a tunnel, seems Omni light it's not casted on smoke particles

This is with sun enabled

This with sun disabled

Also enabling as collision object and collision surface both the particle and the upper node (same mask) still the smoke pass trough and it's not deflected

Hello!

1) In order to make fire smoke visible with Omni Light you need to enable "Omni Light" state in "Lighting" parameters of target particles, since out of the box it is disabled.

2) You don't need to use collision for that, there is special tool coming with ObjectParticles, called "Deflectors", for more info read following article https://developer.unigine.com/en/docs/2.11/objects/effects/particlesfollowing and check our  "Art Samples" demo, scene what you are looking for is called "particles\particles_forces_noises_deflectors.world"

Here is pretty raw example how it should work:

 

And one more thing - make sure gizmo for particles is enabled in helpers to make deflectors visible

Thanks!
