Null Migration Helper | URP/HDRP Converter

OVERVIEW

--------

Null Migration Helper is the ultimate solution for Unity developers who need

to convert their projects between Universal Render Pipeline (URP) and High

Definition Render Pipeline (HDRP). Whether you're upgrading to HDRP for

better graphics or downgrading to URP for broader platform support, this tool

handles the complex conversion process automatically.

KEY FEATURES

------------

✓ BIDIRECTIONAL CONVERSION

• Full support for both URP → HDRP and HDRP → URP conversion

• All features work in both directions

• Reversible conversions with consistent results

✓ COMPREHENSIVE SCENE CONVERSION

• Converts entire scenes with one click

• Automatically converts all materials, decals, and lighting

• Preserves scene hierarchy and object properties

• Optional scene duplication for safe conversion

• Organized asset management with automatic folder structure

✓ INTELLIGENT MATERIAL CONVERSION

• Converts materials between URP and HDRP shaders

• Preserves textures, colors, and material properties

• Supports material variants and hierarchy inheritance

• Batch conversion of multiple materials

• Custom shader assignment option

• Filter materials by current scene or entire project

✓ ADVANCED DECAL CONVERSION

• Two conversion methods: objects in scene or materials in project

• Automatic Decal Renderer Feature enabling for URP

✓ LIGHTING & POST-PROCESSING

• Automatic light intensity adjustment for both pipelines

• Environment lighting configuration

• Skybox assignment and ambient lighting setup

• Emissive materials adjustment (bidirectional)

• Volume profile conversion with post-processing effects

• Exposure, bloom, tonemapping, and color adjustment conversion

✓ PIPELINE ACTIVATION TOOLS

• Clear step-by-step workflow

• Visual feedback with progress bars

• Helpful tooltips and descriptions

• Color-coded buttons matching pipeline

WHAT GETS CONVERTED

--------------------

• Materials (Standard, Lit, Unlit, Custom)

• Decals (Projectors, Materials, ShaderGraph)

• Lighting (Directional, Point, Spot lights)

• Environment Lighting (Skybox, Ambient, Intensity)

• Emissive Materials (Glowing objects, Neon, Screens)

• Post-Processing (Exposure, Bloom, Tonemapping, Color)

• Volume Profiles (All post-processing settings)

• Material Variants (Child materials with inheritance)

• Textures (Albedo, Normal, Metallic, Emission, etc.)

PERFECT FOR

-----------

• Developers switching between URP and HDRP

• Teams maintaining multiple pipeline versions

• Projects targeting different platforms (mobile + PC)

• Asset creators supporting both pipelines

• Prototyping with different render pipelines

• Learning and comparing URP vs HDRP

WORKFLOW EXAMPLE

----------------

1. Open the tool: Window > Null Station > Migration Helper

2. Activate target pipeline (URP or HDRP)

3. Choose conversion direction

4. Select options (materials, decals, lighting, etc.)

5. Click Convert button

6. Done! Scene is converted automatically

The tool handles all technical details including shader mapping, property

preservation, light intensity adjustment, and post-processing conversion.
