Hi Phil, I have used "old" png maps inside XTherion to redraw the cave, but I've never tried to fit the png to the xvi. If that can help you, you will find an example of what I did in attachment.

I’ve been trying to follow Marco’s tutorial : http://marcocorvi.altervista.org/caving/tbe/m_04/m_045.htm But I keep getting the following message : C:\Program Files\Therion\therion.exe: warning -- no data to export Anyone has an idea or some exemple files to share so I can figure this out ? Thanks, Phil
