I download projects and they all have a lot of plugins (like 200+). And all plugins are disabled.
For the first project, I enabled every plugin manually. It took some time.
But now I see that every project has this issue. And I cannot believe that it is always done manually, so I ask for help or advice, how is it done? Or maybe I have the wrong configuration or something like that.
Depending on what you are trying to achieve/ build for you will need certain plugins.
But allot of plugins you may not need so they are disabled by default.
Like i build generally for pc/console so i turn off any mobile plugins since it would only make the install size larger.
So next time you start a project, Think about what you are building it for and make plugin choices depending on that.
Pc? Mobile? Vr?
