I am wondering what could be a good alternative. Scaling down the ranges by a factor 4-5 maybe, so that the longest ranged lights will be visible from a distance of 15-12 km, and shorter lights as La Plate will be visible within a radius of only 4-5 km? what do you think?
@ Kendras

I have noticed that Hitman had created a 20-km environment mod, but unfortunately the link is down

I have also seen that you had a 30-km environment mod planned. Did you make any progress with it?

A set of optional long-range environment mods especially developped for this mod would be a cool addition to it, but I am afraid their settings are a bit tricky

I have followed an empirical method in order to calculate (more or less) the equivalent range of 8 miles in the SHIII world.

What I have done, is plotting that 8-nm range on a nautical chart. Radius length on map was calculated based on the length of one degree of latitude/longitude at Raz de Sein's latitude. There are many on-line calculators that you can get this data from; I used the one below:

http://www.csgnetwork.com/degreelenllavcalc.html

The next step was squeezing the nautical chart I was drawing on, so that one minute of latitude was as long as one minute of longitude (as in the SH world). After doing that, La Plate's circular range became an ellipse.

I then measured the length of major and minor axes of this ellipse (real range), and I calculated the radius of the best-fitting SHIII range as the square root of the square of ellipse's semimajor axis plus the square of ellipse's semiminor axis. This is the result after drawing the SHIII radius on map:

 



Legend:
Red ellipse - 'squeezed' real radius
Yellow circle - SHIII radius (calculated for maximizing overlapping over non-overlapping areas)
Orange area - overlapping area between the two ranges


At this point, knowing that in SHIII one minute of latitude/longitude is always equal to 2 km, calculating the desired in-game radius was a simple math. My result is 15,107 metres, with an ecceptable margin of error caused by the approximations used

Still looking forward to them
