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.

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.
