WolvenKit is able to generate a bespoke material json file when exporting mesh files using the WithMaterials argument. The material json file writes the REDengine shader values and paths to a plaintext json file which can be used in conjunction with the Cyberpunk Blender add-on.
For the latest info about the Cyberpunk Blender add-on please visit the GitHub page directly.
Preparing a material json with WolvenKit is quite simple, export a mesh using the following setting:
Use the drop down panel for Mesh Export Type, and select the WithMaterials option. You will see a material json file created within the Raw directory with the exported glb mesh file.
After installing and enabling the Cyberpunk Blender add-on, simply navigate to File tab, navigate to Import then select Cyberpunk GLTF.
We recommend using Blender Cycles to view meshes with Cyberpunk materials. While some materials can be previewed with Eevee, the multilayered supershader often exceeds the hard-coded limit of 24 image resources.
