Question

How can I get flat shading globally in 3d? Akin to older games and titles, like ps1 or n64 or dos. I know you can manually tick shadowless on every material, not sure about anything else though. I would really rather not do something manually on every individual asset.

Flat shading would be fully lit, no shading on the model, no shadows. I don't mean per vertex shading.

PS1 and N64 did have shading, but yes if you want unshaded models you will have to enable such a setting on each material you use for each mesh. You can use editor scripts to make this easier

Don’t use any lights and you won’t have any shading. Just set the ambient light in the world environment to white and you’ll only get pure albedo on everything.
