Mesh appears pink in the viewport | Substance 3D Painter

Mesh appears pink in the viewport

The mesh can appear pink inside the viewport because the shader used to draw it doesn't compile anymore (as mentioned by the log window ). This can be caused by an outdated shader which doesn't support the latest version of the shader API.

Here is how to fix it:

  • For default shaders: follow the step by step procedure from the Updating a shader page.
  • For custom shader: take a look at the error message in the log window as well as the Shader API page.
