dispenser doesn't show up when I use the remote...
That's strange, it worked okay here...
what map where you playing on, and in what game mode?
Where you with the Dispenser Remote selected? The sentry is kept on weapon slot 3 (by default, press 3 to select it) the dispenser on weapon slot 4, and so on; look at the small picture on the remote to know which of the buildables is currently selected.
I don't like the look of the big pole that comes out the sentry...it should be a tripod like TF2
I actually tried that, but due to a limitation of the engine itself, it wouldn't look very good because the turret wouldn't be allowed to rotate separately from the tripod. By replacing it with a pole, that detail actually goes unnoticed.
This looks great, and it runs perfectly. Excellent modding.
It's my first Doom mod, and it's been very fun to implement.
