I actually do not know a lot about 4th Dimension Mod and 4DC. I think that 4DC is the successor, though.
There are (more precise: were) efforts to rewrite 4DC into a featured mod of FAF. Look here:
viewforum.php?f=32I assume that all effects will be transfered to the new version of this mod as well. Maybe someone like the new explosions so much that he will try to isolate them and put them into FAF. If you have experience in modding, you can do it yourself.
Personally I would like this
http://forums.gaspowered.com/viewtopic.php?f=7&t=51030 to be included into FAF. I could not get the new trees to work, although I think they are much nicer. I think the new trees need 4th Dimension or 4DC Mod to work, though.
But please try the "Graphicenhancement mod v1.1" by placing this folder in here C:\Users\"your name"\Documents\My Games\Gas Powered Games\Supreme Commander Forged Alliance\mods and activating the mod ingame. It is a UI mod only. So if others do not use it, you can still use it.
