Indoor house is dark after baking lights. I have multiple lights source and reflections probes.

Could be due to a few reasons

• First I'd verify that your level geometry is contribute GI static and reflection probe static
• Make sure your light ranges aren't too short, they must overshoot and not be inside static geometry like in the case of your spot light it looks like
• Make sure your level geometry has lightmap UVs, and use the Baked Lightmaps tab and/or scene window's baked lightmap view along with the exposure slider to verify there is lightmap space for receiving GI, and that there would be at least some indirect lighting
• That your directional light is not too powerful compared to your punctual lights, at the moment the intensities of your punctual lights are generally quite low
• That your exposure override is not at an incorrect level for your light intensities
  If you have not yet done light baking before, I recommend starting very small and simple to get something that verifiably does work and then introduce more things one by one

@scenic sonnet It's easy for there to be issues with static flags, or with lightmaps, or with directional and punctual lights coexisting, or with mixed lights not being calcualted correctly, or with fog having incorrect brightness, or with reflection probes reflecting the wrong thing or at wrong intensity, etc

So if you make a whole scene with a lot of independent variables and bake, it can be very difficult to track down what's breaking what

Im trying to replicate how unity did it for their hdrp sample project. I have pretty much same setup. Like all my light intensities are based on the sample and reflection probes as well. I have played a lot with exposure setting but it only help a little. I have tried adaptive probe volumes that gave me awful result that there was a lot of ligth leaks everywhere.

Like I said start very very simple
Swapping to another system with its own quirks midway through is an easy way to get more confused

But those light leaks do suggest that your scene isn't set up quite right
