Awesome! That is what I need,now I can make my AR world looking real! Thank you!

[@KomodozGaming]

Nice, exactly what I'm looking for!

[@GrvShekhawat]

I tested on iOS build for AR game and it works great, thanks!

[@ACatWithACrown]

Legend.

[@b3armonk]

thank you so much!

[@monikg9275]

Could you please explain how you create that material for the invisible plane to receive shadows? I am trying to do the same on Unreal Engine but I cannot find the way to. Thank you in advance

I've checked the repository. You're using AutoLight shadow attenuation macros to compute transparency of the fake shadow. Very clever. However it will not work with multiple lights.

Hello, the new version now can work with multiple lights ---> github.com/Ending2015a/kage

[@targashsensei7900]

THIS. IS AWESOME. Works perfectly except i can't see tilemap if it's on the other side I've been breaking my head for several hours over this, could you help me out?

[@noobvulcan47]

This is super awesome. But how can i make it work in URP?

[@Ending2012a]

Hi, you can see this issue github.com/Ending2015a/UnityShadow/issues/1

[@yogeshks7592]

But the shadow is not visible in game window

[@Ending2012a]

Really😱? It works fine on my computer. I also use this shader to record the video with transparent background.

[@yogeshks7592]

@@Ending2012a Is anything should need to attach to the camera?

[@DaltonSessumes]

@@Ending2012a I had the same problem. No shadow visible in game window. Is this URP?

[@s-litvin]

Same for me (((

[@MatthewRiddett]

Same here.

[@francescorettore8940]

Thanks for the shader! However, for me it only works in Scene mode: as soon as I enter the Game mode (or even looking at the camera preview) the plane is shown, having the same colour of the background. It's a problem, since I need my 3D object to overlap to a Raw Image set as background and the plane isn't supposed to be visible.

[@Ending2012a]

Hello, you have to change the clearflag of the camera to "Solid Color".

[@francescorettore8940]

@@Ending2012a Thanks for the fast response! Clear flag is already set to 'Solid Color' (and I even tried inputting a completely transparent colour (0,0,0,0)), but what I see is a black plane under my object in camera preview and Game view.

[@Ending2012a]

@@francescorettore8940 could you provide your Unity version? Are you using the version newer than 2019?

[@francescorettore8940]

@@Ending2012a Yes indeed, my Unity version is 2021.3.10f1. Do you think that by downgrading to previous versions could solve the problem? What is your Unity version?

[@francescorettore8940]

Unfortunately, I still have the same problem even with version 2019.4.29f1, as reported in your Github repository :(

[@sarthakmusale9752]

I added this to my project and it worked perfectly. but the next day it stopped working, the shadow was not shown in game window. I also removed UR pipeline from project, still not working. any solution??

[@Ending2012a]

Hello, I just update the shader code. Could you try this new version? ---> github.com/Ending2015a/kage

[@Ending2012a]

BTW, this shader does not work with Skybox (camera settings), so you have to change your camera setting to Solid color
