If you want blood to appear on SF instead of the white smoke when you hit someone, its really easy, I do it on ijji SF and Thai SF.. Here's how to do it.
First, go to the Soldierfront directory which is normally at "C:/ijji/ENGLISH/u_sf/" in the directory, find the folder titled "data" and go into it. Double click the config file in it which should be named "config_new" or "config".
Double click on it, if it prompts you about file format and how to open a CFG file, just press choose program to open with and select notepad. Then scroll down to the bottom and locate *setblood "0" and change the "0" to "1" so it should look like *setblood "1", close the file and save it. Go back to the Data directory where the config file is, right click on it, press properties. At the bottom of the properties menu it should show "Attributes" and options Read Only, and Hidden. Tick the Read only option and press apply and press OK.
If the above does not work for you, meaning if you did all the above and no blood appeared, a possibility that the setblood part has been patched by the ijji from your "1" back to "0" so do everything again up to the part after you edit the setblood option to 1.
From there, press the close button and it will prompt you about if you want to save the changes you've made to the file. When that happens, leave it there. Open your soldierfront window and log in, then press play live and after 3 seconds press the YES on the config file prompt whether to save or not.
If all does not work, just live with it, play without blood, too much blood could turn you crazy ^_^
