SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Making an object disappear in a game usually means an abrupt queue_free or a flat alpha fade. This Skill provides a complete dissolve effect — a mesh disintegrating with a glowing burning edge — built from a noise-threshold ShaderMaterial that overrides the target's material, plus a GDScript controller that animates the effect. ## Core Features & Use Cases - Dissolve Shader: A spatial shader that samples 3D FBM noise per fragment, discards pixels below a threshold uniform, and tints pixels near the threshold with an emissive edge color for the burning rim. - DissolveController API: Static GDScript methods dissolve_object and materialize_object that collect all MeshInstance3D nodes under a target, inherit the original material's color and texture, tween the threshold, and optionally queue_free when done. - Named Variants: Ready-made parameter sets for enemy-burn-death, thanos-snap, holy-banish, poison-melt, and summon-arrival effects. - Use Case: When an enemy dies, call DissolveController.dissolve_object($Enemy, 1.5) and the enemy burns away with an orange glowing edge over 1.5 seconds before being freed. ## Quick Start Ask your agent to add a dissolve effect so the enemy disintegrates with a glowing edge when it dies.

FAQPage Schema
How do I make an object dissolve with a glowing edge in a 3D game?▼

Use a noise-threshold dissolve shader that discards fragments below a threshold uniform and tints pixels near the threshold with an emissive edge color. Animate the threshold from 0 to 1 with a tween so the mesh appears to burn away over the chosen duration.

How do I dissolve a character with multiple meshes?▼

Recursively collect every MeshInstance3D under the target node and assign each one a ShaderMaterial override with the dissolve shader. The provided controller's _collect_meshes function handles this, and each mesh gets a randomized noise offset so they do not look identical.

Why does my dissolve pattern slide when the camera moves?▼

In fragment(), VERTEX is in view space, not world or object space. Sampling noise from it directly makes the pattern camera-relative. Transform through INV_VIEW_MATRIX first, then apply inverse(MODEL_MATRIX) for object-space noise that stays attached to the mesh.

Can I use a dissolve shader on a particle system or translucent mesh?▼

No. The dissolve shader is a spatial shader, not a particles shader, so stop particles instead of dissolving them. Its discard logic works in the opaque pass, so translucent meshes with alpha transparency render incorrectly and need a custom dissolve-with-alpha shader.

What is the difference between dissolve and a simple alpha fade-out?▼

An alpha fade sets transparency to TRANSPARENCY_ALPHA and tweens albedo_color.a to 0, which is cheap but flat. Dissolve uses per-fragment noise discard with an emissive edge, producing a burning disintegration look at higher shader cost.

Why does my dissolved mesh turn white instead of keeping its texture?▼

The dissolve shader defaults base_color to white when no texture is wired in. The controller inherits albedo color, texture, metallic, and roughness from the original BaseMaterial3D; meshes using custom shaders need their textures passed manually.
