Resolved URP: Drag and drop render texture to light cookie does not work

In the build in render pipeline you can drag and drop a RenderTexture into the Cookie slot of the Light component.

In URP you can set the cookie to a RenderTexture only with a script. Would be cool if the drag and drop feature would be ready in the final 2021.2 release.

This happens with HDRP too.

 

How to correctly setup light cookie with Unity 2021.2+, it's supposed to work with URP.

 

Did anyone figure out how to correctly add a light cookie in 2021.2+? I have just upgraded a project to use URP 12.1.4 and see the LightCookie field for lights in the editor, with a previously valid cookie, but no cookie is being applied. Note: the texture being used is of type Cookie.

UPDATE: it appears that switching to Progressive GPU (preview) in settings resolves this issue for me. I now have light cookies being applied.
1) Window > Rendering > Lighting
2) Lightmapping Settings
3) Lightmapper

 

This is not at all resolved. Trying to drag a rendertexture in there, blanks out right away. Unity 2021.3.13f1.
correction: it works for directional light, but point lights outright refuse :|

[edit] seems for point-light you need to use a cubemap. Haven't been able to use a rendertexture as cubemap (throws errors), but if that's the required step if you'd like to use rendertextures with point lights.
