Hey,

I know this is a website dedicated to Grasshopper, but since Grasshopper and Rhino are so closely tied, I thought of posting for help with Rhino here.

Alright, I have a site model of an area, and I am trying to render it very simple and basic, namely all the geometry being greyish-white and some light projected to create shade.

Well, one element (the building on site) is indeed being rendered as greyish-white with shading, while the topography comes out as black.

I don't understand why the topography comes out as total black. I even tried adding light to the scenery, but it wouldn't make any difference.

Please, se image for a clearer image of my problem.

Thank you

Marios
