CIvil 3D Drive Visual Styles

[SofiaMo]

Hello,

I have created a corridor in Civil 3D and when I choose the Drive command I cannot change Visual Style. The whole corridor appears green. I attach a picture of it. Do you happen to know why this is happening? I would like to see a more realistic result instead.

is it very important for you?

Well, no, it is not, but since I ask in the forum I believe you understand that I would wish for an answer.

Have you tried assigning Render Materials to the Code Set Style?

Thank you for your reply!

Yes, I do have materials assigned. They come automatically.
