The purpose of this repository is to act as a staring point for Godot games looking to imitate PSX style graphics. I've set up some defaults and included a material to use on your models with some explanation below. Please feel free to open a PR if you have some other techniques or examples that might fit in with this starter pack!
The original PS1 supported resolutions from 256×448 to 640×480 pixels. I've set the resolution to 320x240 for a nice nostalgic 4:3 look, but in reality your player isn't going to use this tiny resolution so we scale it up using the test width/height options. To make sure everything scales properly, we also set the window stretch mode to viewport and aspect to expand. Using this stretch mode we can easily support 16:9 and fullscreen.
The best luck I've had importing models from Blender is using the Godot colloda-exporter (Check the pull requests for a vesion that works with Blender 2.8+) with the following import settings:
I've made these import settings the default for all models.
The important bits here are setting your Materials location to Mesh, storage to Built-In and your Mesh's storage to Files (.mesh). This will prevent your PSX material from being removed every
time you re-import a new version of your model.
When you assign a material to your model's surface, do so on the MeshInstance node and not the mesh itself. Use the psx_material.tres found in assets/materials, right click and press "Make unique", and then right click and "Save".
This will create a unique material for each texture in your game. Take a look in the assets/textures directory for some examples.
I've included a few variations on the PSX material, assets/materials/ray_material.tres, and assets/materials/water_material.tres. These are just some examples, and meant to give you an idea of how you might modify the original shader to get a look you want.
When you want to modify the underlying shader for a new material, after you duplicate the original psx_material, make sure to right click on the shader and click "Make unique" so you don't accidentally modify
the original shader.
Here you just want to disable filter and mipmaps for that crunchy psx look. I've made this setting the default for all textures.
