Drawing natural caverns.

Hey all, I am new to roll20 and am just digging in to the map making tool. So far regular dungeons are pretty easy, with hallways, geometric rooms, etc, but I am having trouble with drawing rough or natural caverns. Is there a way to freehand an area and fill it with a texture like a stone floor? Thanks much.

I would use one of these solutions: Find an existing drawing that you can live with, in art search or Google. Use a tile set you purchase from the marketplace. Use an outside site or drawing program to draw it off of Roll-20 and import it as a JPG file.

Alternatively, if you want to hand-draw it within Roll20, it's probably easier to do it the other way around: cover the entire background with your natural stone texture, then use the polygon/freehand tool to cover the areas you don't want. It's like how you make a sculpture of an elephant: first get a big block of marble, then remove all the parts that don't look like an elephant.

It's better to create your maps outside of Roll20 in something like gimp, photoshop, or maptool and then import that image into Roll20.

Those are awesome answers, above. Al is the man on map appearance. manveti's explanation is funny. that's great. The one resource I can add is <a href="http://www.cartographersguild.com/forum.php" rel="nofollow">http://www.cartographersguild.com/forum.php</a> Cartographer's Guild is an expert mapper's forum where you can ask questions, or post in their Mapmaking Requests subforum as [Paid] or [Unpaid]

Thanks for all the answers, I appreciate it.
