Injecting, texture modding and model changing! 27/4/2010

dude this so frustrating i cant get this dammed mod to work....
ok so i know in deff. doing something wrong couse its not working
so ill xplain step by step what i did and maby u can instruct me in what to do....

ok so first i extracted with (rezextract) the folowing folders
guns_m_pv_ar.rez and guns_t_pv_ar.rez ......

i tthen copied and pasted to a new folder the folowing files.....
ani_g_m16a3_sh.ltb and ani_g_acrsandfire_sh.ltb

so far so good !!!

i then renamed like folows......
ani_g_m16a3_sh.ltb(original) and the sandfire ti ani_g_m16a3_sh_ltb...

then i extracted theese two files from guns_t_pv_ar.rez
pv_ar_df_acr_sandfire_hm and pv_m16a3

i then renamed as folows
pv_m16a3(original) and the sandfire to .... pv_m16a3

i then injected the renamed anibase to guns_m_pv_ar.rez and i ijected the other renamed dtx file to guns_t_pv_ar.rez
