How to achiev better shadows from skylight?

I’m trying to achiev darker and better shadows by just using a stationary skylight + HDRI, importance volume and portals on windows, but I can’t get a good result (like the picture below). How can I get darker and longer shadows with just a Skylight + HDRI, without any directional lightning? Is there any settings to change on World Settings or Skylight that would help to change this shadows?

Hi!

Maybe you could go a bit higher with the bounces…
I wouldn’t go lower than 0.65 int the Indirect Lighting Smoothness!!
Oh and also: I would go back to the new Volume Sample methode and not the old Sparse one!!
What is the size of the lightmap on the walls/floor?

To be honest to get that result: Postprocess!! Set the exposure to something like 1 (both min/max)! Then you can set the brightness of the scene by adjusting the brightness(intensity) of your HDRI shylight or the number of bounces also contol how bright the lighting will be!

I try to attach a 5 mins postprocess on your pic!

Good luck!!
