Bake Shader Tutorial | Export Maya Procedural Shaders as Image Sequences
In this tutorial, I walk through the Bake Shader feature in the ShapeMesh suite.
ShapeMesh assets often use procedural shaders, and in many cases those shaders are animated or driven directly by rig controls. That works well inside Maya, and may even render correctly in Maya, but it becomes a problem when you need to export the asset to another package.
Bake Shader solves that problem by taking the component color information from a selected shaded mesh and baking it out into image sequences. These image sequences can then be used downstream in Unity, Unreal, Blender, Houdini, or any other package where Maya procedural shader networks are not useful on their own.
In this example, I use a waterfall asset whose shader is driven by animation controls. I start with the simple GUI workflow, then take a closer look at the underlying ShaderBoy API.
Topics covered:
• Baking procedural shader channels into image sequences
• Exporting animated shader data from Maya
• Choosing texture resolution, frame range, file extension, and output directory
• Understanding the Rewire Shaders option
• Using ShaderBoy through the API
• Previewing temporary shader swatches
• Rewiring the shader network to use baked texture sequences
• Cleaning up temporary nodes after baking
• Important caveat: Bake Shader bakes the Arnold render shader, not the viewport preview shader
This tool is especially useful when preparing Maya assets for export to Unity, Unreal Engine, Blender, Houdini, Alembic workflows, or any pipeline where procedural Maya shaders need to be converted into portable texture data.
ShapeMesher is my toolset for converting drawn, procedural, and stylized animation workflows into flexible 3D assets inside Maya.
