If you're using the Vector rendering feature in LayOut, you may see the background color of your SketchUp model in cases where it shouldn't be visible. This can happen if there's a hole in your geometry that shows the background color or if the SketchUp window in LayOut clips any geometry. To resolve this problem, you may consider the following steps:
- Try using a Model Style that doesn't include a background color.
- If possible, change your viewport size to include all model geometry.
- Use Hybrid rendering rather than Vector rendering.
