Thanks @Loopysue , I've got one map file per tile type, Chambers w/- connectors - stairs & joining pieces, Passages & Starting Area's. I ended up doing as I posted above, drew guide rectangles 1 snap out over the top of my hand drawn screens then deleted the screens, worked a treat and wasn't really that onerous:

These are 3 starting areas just as a test in Roll20. I'm saving the VTT tiles at 100px per inch and the file name includes the size in inches, i.e 17x5, 7x5 & 9x9 respectively, so customers can easily re-size to suit their preferred VTT.

Hi Ya folks,

Looks as though we'll be coming out of lock down on the 11th Oct which means I'll be back at work, so I thought it best I remove the digit and get these finished...

Here is test in Roll20. As you can see, the JPEGs are picking up the border of the screen I drew. Is there any way to avoid this other than re-drawing the screen 1 snap away? If I change the background colour in Roll20 to the same as the screen I'm still going to have the same issue...

Here are the 2 dungeon level maps. This is a temple that got engulfed by detritus from a volcanic eruption. Created using the Parchment dungeon annual in the DD3 Colour style and CUSAC symbols.

Hi Folks,

I'm running this adventure in/on Roll20. As such, I've copied a couple of maps in CC3.

Here are the first 2, next will be 2 floors of dungeon, the other maps I'm just using screen shots from the adventure as they're not likely to be encounter maps.

And a battlemap size of the villa;

Hi ya Folks,

Here's an update on the spiral stairs. Rather than messing about having double sheets to avoid pixel acne I've decided to just use a fill and draw polygons for the shadows and lines for the edges. Needs a bit of refinement particularly in regards to shadow widths and whatnot but it's looking ok. This is the up version.
