It seems that changing the Weapon Spread in the weapons_ai.data results in no difference. I will check the missions forum, maybe i can find there a solution...
About the MOD merging:
Well, Primary i combinied brettzies m4 weapons MOD with the Colt 1911 Pistol (MEUSOC) included in the M4 SOPMOD. Its not so difficult as you think. The files are written in XML and can be modified easily with the text editor.Every XML File has a unique Function (AI, UI, Weapons i. e.) you just need a bit Time and logical thinking. I know nothing about programming and modding but get it done.
Here are some hints:
-Merge the files of both Mods and remove Files you dont want, for example many mods brings ai improvments,player skins or ui modifications with them. Dont overwrite Files.
-Check the identical Files and search for Differents or specific Lines and add them to the master file.
-Play a bit around, even if you get a crash, GRAW provides good Error Logs with them you can find the problematic files/lines and fix or change them.
