Descrição
WebForge builds spider webs procedurally - orb, cobweb, funnel and sheet - and burns them with a shader that spreads the fire from a chosen ignition point instead of dissolving the whole mesh at once. Light a web where you want and a warm ember front creeps outward across the threads, leaving a charred trail behind it.
It is all C# and a hand-written URP shader. No Shader Graph, no VFX Graph, no third-party packages: the only dependency is URP. Each web is a single mesh (around 3 to 4k tris) and the burn is driven by writing one float to the material, so there is no per-frame garbage once a web is running. Burnt webs can hide or remove themselves on completion, so a scene full of them stays cheap.
Two demo scenes are included, a dark showcase and a stone crypt, both set up for click-to-burn with an on-screen button to reset and replay.
What you get:
Four web types (orb, cobweb, funnel, sheet) with catenary sag and a seed value, so no two webs look the same
Spatial burn: the fire starts at any point and spreads outward from it (per-vertex burn order baked into the mesh)
Hand-written URP burn shader: HDR ember front for Bloom, char trail, alpha-clip dissolve
Shuriken sparks and smoke driven from C#, following the burn front (optional per web)
Click-to-burn raycast component and an on-screen Refresh to reset and replay
Positional 3D burn audio that fades with the fire, clips swappable in the inspector
Completion modes per web (keep, hide, or destroy) with a cleanup delay
Custom inspector: live regeneration, burn preview slider, pick-ignition-point tool, bake mesh to asset
Full C# and shader source
