I need to render my model with a grade that falls off to allow parking underneath the structure entering from behind. I drew my property lines and added grade lines sloping the grade, but no ground shows in my render. Render site is checked in the options box. Tried a few times with same result. I am just fudging in the grade numbers, not working from an actual site plan. Tried drawing a flat grade across the property, same result.
I'm sure it is something pretty simple, but darned if I can figure it out...
