I’m having trouble getting Sketchup to render using Default materials that are included with the program. The Face Style is set to Shaded with Textures. It displays correctly on the screen, but renders all the Default materials as solid colors upon exporting to a 2D graphic.
That solved the material rendering issue as I was trying to export it to a PDF. I’m still have some issues with styles applying changes to scenes, but this was my biggest issue.
