PS1 / PSX Visuals - GD4 Port

This is a Godot 4 plugin providing a comprehensive suite of shaders and tools to recreate the PlayStation 1 aesthetic. It features vertex snapping, affine texture mapping, distance-based fog, and post-processing dithering managed through Global Shader Uniforms.The plugin includes specialized shaders for opaque, transparent, and double-sided materials, along with two key autoloads: PsxVisualsGd4AutoLoad for screen-space dithering and PsxVisualsGd4AutoApply for automatic runtime material conversion.To install, copy the addons folder to your project and enable the plugin in Project Settings. A setup dialog will appear to initialize Shader Globals and toggle autoloads.Users can apply effects manually using the provided shaders or use the Auto-Apply system which replaces StandardMaterial3D at runtime. For fine-tuned control, right-click any node in the Scene Tree to access the PSX Visuals Settings menu to toggle effects or override material types for specific branches.Global settings like vertex snap distance, affine strength, and fog color are managed under Project Settings > Globals > Shader Globals.When updating, disable the plugin and ensure the cleanup options for Shader Globals and Metadata are unchecked to preserve your project configuration before replacing the addon folder.Full documentation available at:https://github.com/scolastico/psx_visuals_gd4

Sprite Shader Mixer

The Godot Sprite Shader Mixer is an add-on for Godot that allows Sprite2D and AnimationSprite2D (Label and ColorRect since version 1.2.0) nodes to blend shaders from a collection of available shaders. Users can select and add shaders to sprites dynamically, automatically downloading them from GitHub as needed. The plugin handles shader generation and blending, resulting in a texture that combines all selected shaders.The add-on allows you to download a set of shaders from a collection (the collection is public on GitHub and you can collaborate on adding new ones). Once downloaded the tool will mix them in a unique shader for your sprite. Since then you can manipulate the shader as usual, customizing the input variables of each shader.version 1.2.0 Update:- Added Label and ColorRect nodes to add shader mixer- default opacity parameter for all shadersVersion 1.1.0 Update:- Added a Search Manager Window to easily select the shaderBasic instructions:- You only need to download the addon folder to your project- Active the plugin- Select a Sprite2D or AnimatedSprite2D node (also Label and ColorRect since version 1.2.0)- At the right, you will see a button to create a shader mixer- Press the button to Sync the list of available shaders (ensure it is pressed, if not the combo will be empty)- Select a Shader and download it (repeat this if you want to merge several shaders)- Go to your material->Shader->Parameters to tune the shaderFULL INSTRUCTIONS AND EXAMPLES HERE: https://github.com/spheras/godot-sprite-shader-mixer#godot-sprite-shader-mixerIMPORTANT: Those shaders are compatible with GODOT 4.1, but not older versions.
