What is godot-shader-previewer?

Godot-shader-previewer is a GDScript addon for Godot that lets you preview shader variables in real-time directly in the editor for .gdshader files. Place your cursor on any line in the fragment function, and it shows the exact value of that variable—like a float mask or vec4 color—at that point in execution. It syncs uniforms from your selected scene node, solving the pain of tweaking shaders without constant scene runs or guesswork.

Why is it gaining traction?

Unlike basic Godot shader previews, this delivers line-by-line inspection with live uniform mirroring and support for bool, int, float, vec2/3/4 datatypes—even multiline assignments. Developers grab it for instant visual feedback in the code editor, mimicking visual shader nodes but for text-based .gdshader work. It's a lightweight fix for shader debugging, akin to github addon managers streamlining workflows in tools like Home Assistant or WoW.

Who should use this?

Godot developers writing custom fragment shaders for effects like masks, lighting, or materials in 2D/3D projects. Procedural generation artists or VFX scripters debugging variable flows without full scene previews. Solo indie devs or small teams iterating on .gdshader files faster than compiling and testing in-game.

Verdict

Try it if you're deep into Godot shaders—solid user-facing features and CC0 license make it risk-free, despite 10 stars and 1.0% credibility score signaling early maturity. Docs are clear with a usage guide, but watch for Godot version breaks on the editor hack; fork and contribute to stabilize it. (187 words)
