Alright, I have updated the download: Now there are blank smoke1-smoke10 & bigsmoke(2) files included, so you can just go and copy the whole content to your Soldat\ folder without need for any further change.
Thanks for your help, guys.
Oh wow. Thank you very much for doing this. I've installed 1.7.0 some time ago and I've been slacking about adding my fav explosion in because I thought I'll have to yet again edit smoke files on my own.
Thanks again.
