Problem with shadows when uploading to Kubity


After uploading my model (an exhibition stand) to Kubity, the lighting/shadows look different than in SketchUp.

For example: In SketchUp, the model is much lighter and not casting any shadows. Whereas in Kubity, the model appears much darker. And when pulling the light control up and down on the right side, it doesn’t just get lighter and darker; it casts shadows which I toggled off in SketchUp.

I need to send this to a client ASAP and would much appreciate any help I can get to solve this issue.
