Differences in 3D Model Viewer Sceneviews

[Mehequanna]

Hello!

I've been playing around with the 3D Model Viewer sample. I'm trying to figure out some lighting. mapping, texture issues I'm seeing in my app.

What's perplexing me about the 3D Model Sample is the two sceneviews display so differently. I've made them identical in the code, for example, rotations, transparent backgrounds. But the scenes still look very different. Could someone please point me in the direction of how and why the backdrop cloth and the lighting are so different in the sceneviews?

Thank you!
