Hi Cecilia,

I can see what you've done with the models.

I tried the same settings on another project and once again I have some weird shading on the Data Racks - See image (what would cause this)?

I created a white PNG 1000px x 1000px which I used for the floor and the sky but not sure if that's correct or the right size?

I have included the link to the project below.

Sorry to keep asking all these questions and thank you so much for your help on this.
