it was working on previous scene but when i opened downloaded scene i cant setup now( what i need to doublecheck?
Maybe try the latest 2022.1 version?
Also if you don’t need 2022 features just use the latest LTS.
You can try to setup a 2d URP project using the 2d URP preset. From this you can see the settings for a working project
how to setup using preset? i downloaded presets and how to import to my scene?
also i reinstalled URP and cant see 2d lights now
You start a new project with it and them import your current files to that project.
In unity hub press new and then select the 2d urp preset
