I would like to know why after years of development and various pipelines, when we use the point lights, the shadows of the objects are still completely detached from the base.
This is the result with bias at 0:
Standard
Urp

Welcome to real time rendering? They’re not a solved problem for any engine. You can sometimes hide the problem in some cases using screen space shadows, but that won’t catch 100% of the issues, and can be expensive. Raytracing can make those shadows perfect, but are even more expensive, and often add a lot of noise. Real time shadows are hard.
Unity’s shadows used to be much, much worse than they are today, so this is actually the “fixed” version.
One option you can try is NGSS.

These add several new features to Unity’s built in renderer shadows. But again, come with increased cost, or visual noise, or require some special handling to get the best results from.
Now I don’t want to raise the usual Unreal vs Unity controversy, but it seems to me that the shadows are clearly superior on the other Engines.
This is the shadow in Unreal
Specs : In both cases I’m using realtime rendering on Nvidia rtx 3080.
you can try it yourself if you want.

man you are comparing shadows between engines that target different device by default.
URP and BuiltIn are mobile first from the beginning. While unreal targeting PC/console by default.
The implmentation are different, the cost of performance are different.(and of course your nice 3080 can handle much demadning one with ease)
If you really want to have nice shadow you can try HDRP .you can try it yourself if you want.

Sorry admit I made a wrong comparison!
However, although HDRP achieves a better effect, it is still unsatisfactory.
Now I don’t know why if I set the quality to ultra the shadow completely disappears but I still remember that some empty corner is always visible (albeit better).
HDRP
Some parameters need to be tweak(but it’s fairly simple) in hdrp in order to get good shadow for you.

This video made by Pierre is probably the best first guide for HDRP setup.
check the 38:36 part of shadow setup. You can still get really good looking shadow.
I can understand the whole process is more complicated than using Unreal. Where eveyrthing looks good out of box. But this is pretty much the Unity experience at current state…in order to get good result. The users need to put some exta effort.
Regards the directional light there are no problems ( after the various necessary settings ) either in Built In and URP.
In this discussion in fact I refer to the “point light”.
With the "point light" in my opinion we are still far from having a good result.
Setting the contact shadows instead you get the coverage of the contact angle, but with a very ugly irregular edge.
