Why does a part of my texture remain black in 3d view?

[Tapiir]

Hello, I've just started using Substance Designer and I ran into a problem where a part of my texture remains black in the 3d view despite the base color node showing that there should be color. Any idea what could cause this?

After adding new outputs, right click the background of your graph and select "view outputs in 3d view" for them to show up in the 3d view.

if your ambient occlusion is black, this will also happen.  To test this, create a uniform color. make it white. Right-click-drag it onto the 3D viewport and pick AO.  If the issue goes way, then you know it was the AO all along.
