    In feature comparison picture , I found shadow resolve type lighting pass and screen space pass are both supported in urp. I took a look on framedebuger ,I think it is solved on lighting pass by default . so is there anyone who can tell me how can I change to screen space shadow ( on lwrp , maybe toggle on the cascades will change to screen space shadow but I have tried on urp ,it didnt work i think )

    From my understanding, the screen-space shadow pass was completely removed in URP 7.2.0. I've had a look in the shaders and it does indeed seem to be completely gone, the only reference I can find is a single line: "#define SHADOWS_SCREEN 0". Changing this wouldn't actually do anything because the define is not checked anywhere else.

    You can find more information on why it was removed on this page: https://docs.unity3d.com/Packages/c...universal@7.2/manual/upgrade-guide-7-2-0.html
    The page doesn't mention it (although I think it should) but this also fixes a long standing issue with shadows and MSAA.

    It would seem the feature comparison page needs an update.

    Yes, we recently removed screen space shadows as they caused quite a few issues with XR and also transparent shaders did not play nicely, so currently it is removed. We have plans to add them back in at a later date, and also give users the ability to override them(the render pass itself or render into them without having to alter URP code)
