Blender Custom Shader exporter

This Addon Exports your custom PBR Shaders for use in other 3D Software like Unreal or Unity

How it works

The Script will search your Blender File for all objects materials and export information about each the ShaderGroup used in each Material to a file.

It will export this Information to a Json File, which can be used in other 3dSoftware.

Information that will be exported:

• Object:

  • Object Name
  • Material Slots
  • Material used in each Slot

• Materials:

  • Material Name
  • Custom Shader type
  • Textures attached to each Node
  • Material Values

Installation

There is no Proper Installation method yet. For the time being the Script can be launched from inside Blenders Script editor.

Run the Script via Blenders Text Editor:

• Inside Blender, go to the Scripting Tab or open a new Text editor window
• In the Header go to the Text-> Open then browse for the Python File: materialexporter.py and open it

The File can then be executed directly with no setup Needed, if your materials are Set up Correctly (See) How To Use Section

How to use

• Make sure, your textures are stored in a dedicated Location on your Hard Drive and not packed in the Blend File

• Make sure ALL your materials are set up like this:

  Sample Setup

  

  • You can put your Shader Magic in the Group Node.
    That way it will look Similar in Blender, as you would for example Recreate it in Unreal Engine or Unity.

  • You can put as many slots as you want as Input for the Node Group, but the Script will (for now) only Recognize and export Textures/Float Values of these Slots:

    • Diffuse
    • Alpha
    • Roughness
    • Normal
    • Specular
    • Metal
    • Subsurface

  • Put Your Textures in the Sockets or twak the values

  • Every Texture Node Attached to the Group, Should have a valid texture in it

Known Errors

• No export of Color Values

• No export of Vector Values

• Many more Errors, this addon is still wip

Future Plans

• Proper Error catching
• Make it a proper BLender addon with a decent UI and all that Jazz
