Gradient sky fades with time and becomes gray in HDRP

Hello there,

I have another post where I was asking about the ambient light in HDRP, one of the responses was to use gradient light.

I did that and I set all of its values to white (255,255,255). However, as clearly visible from this video gradient-problem.mov - Google Drive the light vanishes after a number of frames, and the white plane becomes grey…

I tried changing the exposure of the sky with no luck.

Any clue?

That’s most likely auto-exposure from the default HDRP settings being applied.
You can either change the default HDRP volume profile (in the project settings) to not have auto exposure by default if it suits your project better or just override exposure locally in your scene with a fixed exposure.

You are a legend!
Thanks!
