[Roof not creating a shadow during render]

I had already tried restarting the file, and vectorworks, to no avail. The Fill is set to solid, black color.

 

In a new file I put tried a roof with the same texture and same everything else, and it worked as intended. I copy and pasted that Into the original file, and it works now!

 

Thanks for the help

What Renderworks Textures have you applied to the roof?

Not 100% sure what you mean, would this be from the Object Info Panel?

 

I have the Overall and Top set to a dark wood grain.

[Roof not creating a shadow during render]

Hello,

 

I am planning a university commencement can want to see what kind of shadow the tent covering our stage would produce during the ceremony. To do this, I figured a roof would produce a very similar shadow, but when I put it into either fast or final render, the roof disappears. I have attached images below that shows the roof in OpenGL and then Fast Render

 

How would I fix this to show a shadow?
