Setting Skybox Exposure through script
Hi all,
Anyone know how to do this? I am dimming my scene the usual manner, by dimming the lights in it, but the procedural skybox is staying bright and vibrant as ever. I need to dim it (doing so via a lerp in a coroutine) but I can't figure out how to change the Exposure parameter. I've tried SetFloat("exposure",...) and SetFloat("Exposure",...) but neither work.
Can anyone point me in the right direction?

Found the problem. It was the keyword I was using - instead of "exposure" or "Exposure", I needed to use "_Exposure" as the keyword name. D'oh!
Do you $$anonymous$$d showing the syntax/line of code that changed the exposure?
Thanks C
Here's an example - fading in the Skybox
for (int i = 0; i < 10; i++)
{
yield return new WaitForSeconds(interval);
exposure += 0.3f;
RenderSettings.skybox.SetFloat("_Exposure", exposure);
}
I did it with a coroutine:
float exposureStart = 0.6f;
float exposureEnd = 0.2f;
float currentExposure { get; private set; }
float fadeTiming = 0.5f;
private void fadeDown(){
StartCoroutine(Fade(exposureStart,exposureEnd));
}
IEnumerator Fade(float startAlpha, float endAlpha)
{
float elapsedTime = 0.0f;
while (elapsedTime < fadeTiming)
{
elapsedTime += Time.deltaTime;
currentAlpha = Mathf.Lerp(startAlpha, endAlpha, Mathf.Clamp01(elapsedTime / fadeTiming));
RenderSettings.skybox.SetFloat("_Exposure", currentExposure);
yield return new WaitForEndOfFrame();
}
}
