As pabbi points out, there is a SCAF edition for TMO 1.4 (it's this
download).
But.....you need to know the limitations of SCAF compared to OTC.
As anyone who has played the game realizes, the stock game misses the mark with manual targeting (pun intended!). My attempt to fix a broken system was to make sure the stadimeter heights were as close as possible to giving a player an accurate range finding when using the stadimeter. My problem with SCAF (which had several generations of updates), doesn't take into account that the sub will give different range measurements depending on which direction you take the stadimeter measurement from. It's a stock issue and was passed on through mods that didn't know such a problem existed.
Second, the periscope/TBT scope lens have no way of providing a measuring tool for range finding. To be sure, that's why the Telemeter Divisions are on the lens......but the game doesn't consistently render the Camera View (what you see through the scopes) at an accurate Field of View width to make that possible. So a very basic and authentic way a measuring targets is nothing more than eye candy with the stock system. SCAF does nothing to these views since I didn't (nor anyone else) know this problem existed. Only after extensive testing did I begin to see that the different resolutions/aspect ratios change the camera view, making them different to each player. The stock game Telemeter Divisions are useless to any kind of measurement capability.
Third, the SCAF mod doesn't provide any changes to the games radar (either surface or air). You've got the same stock radar setup that's very much like the Telemeter Divisions on the scope........their just eye candy. The surface radar has no way of measuring anything. It will miss a nearby target as easily as a far off one, and you won't have a clue as to how far away it is. You'll get somewhat of an idea of the blips bearing (when it works) but that's it.
I could go on but you get the idea. OTC was designed to be the next generation for SCAF. Giving you accurate dimensions (both height
and length), and providing a game "view" that allows for measuring those dimensions accurately (no matter what resolution/aspect ratio a player uses). It's what we expected in the game but never got.
Another suggestion is to buy (for less than ten bucks) the SH4 Gold Edition bringing up your game to version 1.5. Buy a CD version....no downloaded STEAM upgrade! You'll be happy you did, and never need to play the Nazi's side in the Pacific!?!
