Foxioo Shader Pack is a project I’ve been developing since 2024, and its goal is to "fill in" the gaps in many effects within the Fusion community also i made it for a hobby and learning purposes;
- In 2022/2023, I began experimenting with effects, learning the basics of HLSL, and modifying and building upon effects created by Looki (Interestingly, I still have those effects on my hard drive from that time, and they haven’t been published in FSP-maybe I’ll publish them, but in improved versions).
Over the past year, I’ve realized that I’ve accomplished a lot, but is it enough?
- I want the effects to be available on every Fusion runtime; I’ve learned GLSL and delved deeper into HLSL, discovering cool things I can do.
How long will I continue to support FSP?
- As long as possible, adding new effects and improving the old ones, because even when Fusion 3 comes out, FSP will be updated to support the newer version of Fusion (while continuing to support Fusion 2.5).
Shaders are amazing; thanks to them, I created another project called Tails7, which also replaces the outdated MMF2-era extension (namely Mode7Ex) with a framework/engine that runs on any runtime that supports effects, runs much faster, and adds support for simple polygons.

I'm count the number of effects in the latest release; there are currently 420
- The last release was on April 13, 2026
- FSP release requirements:
- Minimum: Build 295.10 (Due to the
_Is_Pre_296_Buildflag, but starting with Fusion build 297, support will be removed and the target version-along with the minimum-will be the latest; if you are using old Fusion build, why?) - Target: Build 296.9
- Minimum: Build 295.10 (Due to the

Work is underway in the main branch on a new release, which will be available for Fusion build 297; many effects will no longer be compatible with older FSP and Fusion releases
Effect Categories:
| Category | Description |
|---|---|
Blend Modes |
Various effects called blending modes that you will find in graphics programs. They use colors from the object's texture and transform them in various ways using background colors. |
Coloristic |
Effects in this category can manipulate the colors of your object's texture or background. They include colors that can transform hue, brightness, mask color, and similar effects. |
Special |
Effects in this category are intended to simulate a given thing or replicate shaders from other games. |
Transformations |
Effects in this category transform texCoords to scale, rotate, and offsets pixels from the texture. |
Unused or Experimental |
Effects that are only for testing purposes. |
Number of effects from 3 different types:
| Type | Description | Sum |
|---|---|---|
Background |
These shaders use the object texture and the background texture for calculations OR only background texture. | 208 |
Switch |
These shaders use either the object texture OR the background texture depending on the setting of the _Blending_Mode variable. |
153 |
Texture |
These shaders use ONLY the object texture OR object with external texture | 59 |
| Number of all effects | 420 |
Platform Support
| Platform | Description |
|---|---|
Windows (Direct3D 8) |
A very old API that supports up to Pixel Shader 1.4; shaders written in assembly language with very significant limitations; I know how to write effects for Direct3D 8, but it’s not worth it right now-why? The .fx file is shared by Direct3D 8 and Direct3D 9, so if I write an effect for D3D8, I limit the effect for D3D9; if only the files weren’t shared and D3D8 had a file format like, for example, .fxasm, I’d be more than happy to support it; I can only hope that Clickteam changes this.It’s interesting that I’ve probably written the only working effect for D3D8 over the years-looking by various forums and information, no one else has created anything for D3D8 for CTF/MMF2 |
Windows (Direct3D 9) |
This is the basis for the effects in CTF/MMF2! Of course it supports them! (Not counting those more advanced effects that don't look the way they should or are "worse") |
Windows (Direct3D 11) |
Supported. |
Android |
Supported. |
iOS |
Supported. |
macOS |
Supported. |
HTML5 |
Not supported because the HTML5 Runtime CURRENTLY does not allow it; I'm are waiting for HTML5 Runtime V2, at which point it will be supported. |
Haxe |
It hasn't come out yet, so how am I supposed to support something that hasn't come out yet??? |

- Click on the "Code" button then "Download ZIP".
- Open Clickteam Fusion, go to the "Tools" tab and click "Windows Explorer". This will show you a window where Clickteam Fusion is installed.
- When the window where Clickteam Fusion is installed shows up, open the ZIP file you downloaded before and in this ZIP file go to the "FoxiooShaderPack-main" folder. In this folder, copy the "Foxioo Shader Pack" folder and paste it in the "Effects" folder where Clickteam Fusion is installed.
- After the installation process, go to the "Workspace Toolbar" window, select your application and click "Properties".
. - Go to "Runtime options" and make sure "Display Mode" is set to "Direct3D 11" or "Direct3D 9".
