Moth's Useful Instances
Some useful instances I made, that can serve two purposes:
* Quickly add nice things to your map
* Deconstruct, use bits, make new bits, gain UNDERSTANDING 
My plan is to expand this as I make more stuff.
Each instance has an accompanying screenshot of all 4 Hammer views, so you can see what it looks like without launchiing any tools.

Feedback is welcome, please rate this and post your comments. I'll post when I update.

There are some really nice instances, thanks for that!
But maybe it's useful to put them in your description as well?

Good idea! - Updated main thread with a collapsible list

You should be a Community Contributor after uploading all of THAT. 36 instances, that's impressive. I could only stand doing the Disc and Disk Player set I made and that took about week. You must have a lot of motivation to create 36 instances.

My only motivation is the desire to be a better mapper. I came to Hammer from Radiant - the transition between editors was an absolute nightmare. I didn't know about instances then, and wished more than anything for there to be prefabs, to increase my efficiency and help me to learn.
I've been working on these since P2 Authoring Tools was released. My ultimate goal is to go through all the campaign maps (sp, coop and dlc maps) and isolate sections in a similar manner to these. Rather than blatantly copy and paste Valve's work, I will be re-creating as much as possible, which will improve my skill, and help contribute to this community, which I owe everything to.
.. oh, and there's more than 36 - There's also a 'unique' folder - got to leave SOMETHING as an easter-egg

Of course.

When you rotate the fan, the axis of the rotation stays
I dont think that he will fix that after 3 years ...
That's not something that can be fixed, because it uses a func_rotating.
