Hello together,
I can´t figure out the geog image map shader.
I try to use a set of global masks in jpg format(for ice, rock, sand, forest, whatever). All these masks are derived frome one global map, being basically layers of one file they are completely congruent. When I want a geog image map to cover my whole planet, I obviously need coordinates like in the attached image. By trial and error I found out the combination that matches my base maps orientation. Assuming that the same coordinates that work for my rock map will also work for my ice map, I copied the geog image map shader and only changed the image file. But that doesn´t work, sometimes I have to change the coordinates, and sometimes it doesn´t appear at all. I don´t understand that.
Any ideas?
Thanks,
Jan
