You have to make the barrel, then just make it a func_barrel. If you read the entity properties for a func_barrel (key N) it tells you all the options.
That's exactly, what I was afraid of...
As far as I have tried, I have to use a brush to make it a func_barrel and a curve to get these f*#?ing textures aligned!
If you open the test_firefight map youll find barrels and how its done...or just copy and paste ..or save as prefab {or is that breaching copyright?}
that i how sused it..sort of..
When you copy a barrel, remember to copy the cap as well. Some barrel caps are in 4 peices. Also watchout that your red fuel barrels doesn't have the word on the side written backwards--may need to flip the texture.
