Visualisation in OpenRoads

Goodday,

I recently started using OpenRoads connect edition and i've been facing some difficulties.

- Firstly, I wish to know how I could get the vehicles in the image below get their realistic colours, I have tried all the display styles and even after rendering they remained dark.

-Secondly, I imported my terrain as an XML file from Civil 3d and wish to apply a material to it. I tried creating a mesh over it but the mesh now covers my corridor even after clipping my terrain.

-also how do I clipped a terrain over a civil cell at an intersection

-how do I get the cell file for street furniture

I will greatly appreciate solutions to these and I apologise if these questions don't are not related to this community. Thank you
