Ambient Light with HDRP

Sorry if this sounds a dumb question,

For experiments purposes, I'm trying to create two identical scenes (one using the built-in render pipeline, and the other using HDRP).

As I'm a newbie to HDRP, I couldn't understand how to set the ambient light color as in the built-in renderer? ( I don't want to use directional lights at this occasion)

I tried using skybox, exposure, but all of them ruined my scene (white cube becomes a light blue, as an example).

I also followed what's in the default HDRP scene, but I actually couldn't arrive to a conclusion.

Am I missing something?

Thanks in advance!!!!

 

You can get Ambient Light with Gradient sky or HDRI.

 

I'm currently using HDRI, but I'm suffering from the problem I mentioned above. White cube turned out to be light blue..

 

Here is an example, not the cube but the plane

I set the colour of the cube to yellow
and the plane to white, but the plane actually looks light blue

Bump ?

is there a way to set the ambient light as the built-in renderer. If not, I want to mimic the behavior of a white (255,255,255) ambient light. How can I do that with either the sky or the exposure?

Any help would be greatly appreciated...


Update: setting the static lighting sky to Gradient sky and changing all the colors of the gradient sky to be white works for previous version of hdrp (5.2) but not the 7.3

 

This is one of the unfriendly parts of HDRP. Want white background/sky, erm... gradient sky, but I have to set 3 colors to white! Then it comes out grey because... well let's add an exposure to the volume & now it is white. But everything else in scene is too bright so up exposure or auto expose.. ok we have ambient light control but oh sky is grey again!

So I guess exposure is your ambient light control and the sky will change depending on this unfortunately (camera-real?)

You can just have no sky and set the background color but strangely the background color will be more grey still...

 

It's a good video, an indoors one might be useful as the outdoor scene is maybe best case!
Also indoors you need to know how to do a realistic lighting setup, lumen values etc.

I think for newcomers it is about the fact that you are now dealing with a realistic camera & lighting setup, not just flooding the scene with lights (ambient included) to get the look!
