Welcome to the UNOFFICIAL shader documentation for Clickteam Fusion.

Most of the pages need to be rewritten because a lot has changed in Fusion build 297!

The documentation is a segregation of all shader knowledge, technical information on how to create shaders, etc. in Fusion.

All information is based on:

• Official HLSL and GLSL documentation websites
• Knowledge and experiments
• Numerous online forums on shaders
• Official Clickteam forum

The documentation is constantly updated with new information, last change: 05 April 2026 (Early WIP)
