here is a modification of the worldmap located here : https://github.com/coyled/Egress/tree/master/webmap
You can get the tiles directly from an OpenSim.exe or Robust.exe instance (idea from https://plus.google.com/+StephenHart/posts/566eNVhBBrk ).
- If you convert assets locally, you need to install
- OpenJpeg-tools
- change the values in the files located in the "config" folder.
- put the script in a webserver and go there with a web browser.
