Sample a noise dissolve map, subtract a Dissolve Amount parameter, and feed the result through a Step node into the Alpha Clip Threshold. Add a second Step offset by Edge Width multiplied by an HDR Edge Color for the emissive edge, and encapsulate the logic in a reusable Sub-Graph.

Create a ScriptableRendererFeature that instantiates a ScriptableRenderPass and enqueues it in AddRenderPasses. Inside Execute, use CommandBufferPool and Blitter.BlitCameraTexture to apply your material; never use OnRenderImage, which is built-in pipeline only.

URP custom passes use ScriptableRendererFeature with ScriptableRenderPass, while HDRP uses CustomPassVolume with CustomPass components. The APIs are not interchangeable, and a Shader Graph authored for URP will not work in HDRP without porting.

Black materials usually come from cbuffer properties that do not match the Properties block, or from using direct sampler2D declarations instead of the TEXTURE2D and SAMPLER macros from Core.hlsl. Declare all properties inside CBUFFER_START(UnityPerMaterial) for SRP compatibility.

Mobile shaders should stay under 32 texture samples per fragment pass and 60 ALU instructions for opaque fragments, with 40 ALU for transparent. Avoid ddx/ddy derivatives on tile-based GPUs and prefer Alpha Clipping over Alpha Blend to avoid overdraw and depth sorting issues.
