Hi all - my first post here. I've made my 1st track complete with altitude variation, cambers and surrounding terrain. It took me three weeks to discover the 'w' key is used to make the wireframe visible - which brings me to my question: I'm trying without success to add about a metre of gravel/dirt to the side of the driving surface as shown in one of the video tutorials using the track cross section tool. Am I missing something obvious or what? Could some kind person give me a step-by step guide to do this please?
