Author Topic: Substance Painter Metallic/Specular Smoothness map issue. Repeating squares/dots  (Read 255 times)

Issue: When using a Metalic or Specular map from SP in Unity 2020, building for iOS, and using the Universal Render Pipeline, a repeating pattern of squares/dots appears on the model. Removing the map solves the issue, as does switching the build platform (in Unity) to Windows or any other.

I get the same problem using both the default export texture options from SP and with custom-made export options.

Below is the effect I am seeing with and without and without the map.

I have searched High and low for a solution to this but I have found nothing, apart from this unresolved post -

Can anyone shed some light on what is going on here?
