lighting hdrp

hello,I' ve a lighting settings asset and I'm basically trying to change my environment's lighting indirect intensity but when I'm changing its value and rebake the lighting, it doesn't do anything,I can see the changes with a directional light but it's kinda weird, when I set the indirect intensity to 1 from something like 10,I can't see the changes but when I add a directional light and dicrease the intensity, I can see the changes and then once I remove the directional light and rebake it gets full dark

Since you are using HDRP, your scene likely is using automatic exposure
Directional lights tend to be very intense relative to ambient light on default settings, so when automatic exposure adjusts for the directional light's light level, ambient will be imperceptibly dark

You'd bring their intensities closer to each other and optionally use another mode of exposure

Iirc HDRP also can use the visual enironment for realtime indirect light and reflections so baking might not be necessary

oh okay thank you so much, there are also too many things in the settings and volume parameters, do you know how I could learn all them? I've tried to find a good tutorial on this but they only show the basics such as the sky etc

This might be the most comprehensive and up to date one, but I'm not familiar with all the resources
