Smoke issues

[John Price]

so I have a modpack that I give to my members: http://www.mediafire.com/download/18gtub1niy7zuyq/74th_Mod_Pack.zip

Although it changes the smoke textures or something (the puff of smoke is bigger and stays around for longer). It makes it impossible to see although I do not see any clear file as to deleting the issue or what to change to fix said issue.

Any help would be appreciated
