I've established my model with a terrain model, draped an orthophoto and imported my road. Beside the road I want to fill the areas with coverages - for example grass. Everytime I'm drawing an area with coverage (randomly picked) the polygon visualizes with randomly lines along and across the polygon (see attached jpg).
Is there a way to remove the lines? And why do they show up? I've seen some tutorials on youtube, and I've never come across the same "problem".
Please help. Thanks!
I didn't find the right solution from the Internet.
