I have to do a pretty simple effect but I can't use dt fiel.
What I need to do is set an initial velocity to my particle and for example after 2 sec i want to increase gradually the emission speed till second 3 (for example start with an emission velocity of 0,1,0 and from second 2 to second 3 of the sim gradually increase till 0,3,0).
What I've tryed was in spawner script
Velocity = float3(0,1,0);
Then I created a CParticleEvoler_Script and inside I tryed in every way to multiply Velocity with dt but it always have a 0 value.
What am I doing wrong? How can I use that field??
Thank you for your answers,
