RE: https://github.com/domlysz/BlenderGIS project , ty btw for this OP 
I tried to find a post I’d made, and its gone it seems so I have to restart, and the point was I treid to load a tif file I downloaded from open topography , and while I know chose ‘raster’ from ‘data’ at top of page, and then chose ‘global 30 M srtm’ which is also raster format, I kept getting the error ’ unable to load worlfile’ .
Where can I find this raster of the type wrl or tifw, etc. ?
