Shader for Playstation 2 like screen resolution.

ThecoffeeANDsoda

I'm not sure if anyone has made a thread regarding this topic but I am aware that on other engines developers try to make the resolution of a PSX or N64 like game look lower then what is normal in games that are designed for high def computer monitors and flatscreens.

Isn't their a way to implement a shader that gives the look of a lower resolution standard definition tv set?

Thanks.

You mean something like this?

edit: If yes then it's all about understanding how CRTs worked and what a shadow mask is. Basically you render into a buffer/viewport and then apply a shader to it to emulate a shadow mask.

If you're after the PS1/affine texture mapping vibe:

However you will have to also tailor your models to suit the low poly/plane look and if your serious, draw backgrounds yourself. As for downscaling the resolution itself, this is found in project settings.

Interesting side note, the PS2 was actually 1080 capable, it was just only realised in about 5 games. But I think that's why internal textures for a lot of late stage PS2 games seem to be excessive for the original 480p screen resolution. At least this would explain why games look surprisingly good when upscaled using an emulator, for example FF-12s textures at times looked comparable to Lost Odyssey's when played at 1080 on an emulator (though still abused motion blur to take the edge off the edges).

More like 2000-2002 playstation 2 games.

I honestly can't remember where I found mine (kinda accruing screen shaders over time), but this looks similar and may be what your after: https://github.com/hiulit/Godot-3-2D-CRT-Shader

It says 2D, but really it just requires a fullscreen TextureRect which can have 3D behind it.
