I've an explosion effect using particle system.

Explosion occur on air, so I want to add a "flash" light effect when explosion occur (that light sky and terrain ).

Can you suggest me best way to obtain ?

    \$\begingroup\$ Presumably you tried adding a point light and adjusting its brightness along an animation curve? Or adding a sub-system with a lights module? How did these attempts work out for you so far? What concretely did you try, and where did you run into an obstacle you need help overcoming? \$\endgroup\$

  • \$\begingroup\$ Exactly: finally i've added a point light and a routine that increment (and decrement) intensity and range. And yes.. I can say result is good. \$\endgroup\$

I've just added a point light with a script that increase (then decrease) :

  • intensity

  • range

in a fixed span time .

This is my script:

public class gsFlashLightExplosion : MonoBehaviour

{ [SerializeField] int LightStartRange;

[SerializeField] int LightEndRange;

[SerializeField] float LightStartIntensity;

[SerializeField] float LightEndIntensity;

[SerializeField] float Speed;

private bool blnRun=true;

private Light light;

// Start is called before the first frame update
void Start()
    light.range = LightStartRange;
    light.intensity = LightStartIntensity;

// Update is called once per frame
void Update()

        light.range = (int)(light.range + (light.range * Speed / 100));
        light.range = (int)(light.range - (light.range * Speed / 100));

    if (LightEndIntensity > light.intensity)
        light.intensity = light.intensity + (light.intensity * Speed / 100);
        light.intensity = light.intensity - (light.intensity * Speed / 100);
