RenderMan for Substance Painter 2.x

This plugin exports your Substance Painter project as one or more RenderManAsset.

RenderManAsset is the format used by the preset browser that was introduced in RenderMan For Maya 21.0. It allows for easy material setup interchange and includes dependencies like textures or OSL shaders.

Features

: Export to PxrDisney-based material

The asset will use the PxrDisney bxdf to re-create the Substance Painter material. There are limitations though:

• The Substance Painter project MUST use the pbr-metal-rough shader.
• normals MUST be in directx format.
• Opacity is not supported.

: Export to PxrSurface-based material

• The Substance Painter project MUST use the pbr-metal-rough shader.
• normals MUST be in directx format.
• Opacity is not supported.

Requirements

This plugin will NOT work without the following software:

• Substance Painter 2.3+
• RenderMan Pro Server 21.0+
• RenderMan For Maya 21.0+
• Python 2.7+ (but not Python 3.x)

Install

• Download a zip archive from the github page
• Un-zip the archive
• Copy the RenderMan folder inside Substance Painter's plugin folder.

  OSX: /Users/yourlogin/Documents/Substance Painter 2/plugins

Known Issues

• No progress indication during export: be patient !
  • It takes time to export the maps and turn them into textures. The plugin will print a message in the log when done.

Usage

1. On first use, open the "configure" dialog.

   

2. Fill ALL fields of the dialog and click "Save", otherwise the export will fail.

   

3. Once this initial configuration is done, the settings will be remembered even if you close Substance Painter.

4. Open a SP project and click one of the pixar buttons in the shelf.

   Hint: Only the first one (PxrDisney) works for now.
