I will be changing the CAF mod to the IWAR one you linked on Teamspeak. Cannot do much about the clipping issue besides switching to an A3 map.@Krystal LeChuck
The biggest issue i faced today is enemies clipping through the textures, so you can only shoot them looking at their tracers. This was in AllInArmaTerrainPack, this also exists in CUP_Terrains and probably all ArmA terrains using A2 assets.
Also their guns does not have sound since CAF AG hasn't updated for more then year. If you really want to stick to CAF, i can try making replacement configs for them, so CAF units will use RHS weapons.
Otherwise it was pretty fun.
By the way, is there any good guide on ACE medical?
