Model Ports
Here are a few things I've fixed up, usually from the HL1 engine, to work in SFM. They're probably not enormously interesting to the vast majority of SFM users, but they're there if you need them. It's because I care. Or because I'm damn good at pretending I do. Either/or, really.
Moderately-Priced RT Camera TV
A generic, unpretentious, mid-range television from an era not unlike one we just left, ripped from The Sims 3. The screen on this TV displays the RT Camera texture by default. Using this, you can display anything on it using a secondary SFM camera! The possibilities are only limited by how far your audience is willing to stretch their belief as to anybody still using a CRT!

TF2 Skybox Model
Some squat little skybox models so that you can display any skybox from TF2 at your whim! Unlike changing the skybox in the console, this lets you rotate and move the sky around to best suit your desired shot. Give your favorite maps a whole new atmosphere with this one simple trick! Doctors hate it!

Quake Players
The player models from Quake 1 and 2. Converted from HL1 ports found on Fileplanet aeons ago, the credit long since lost to time.
The Quake 1 player includes the Quake Team Fortress player skins as a bonus.

HL1-Era Counter-Strike
Quick-n-filthy ports of the classic CS 1.6 player models. Also includes the Chicken, VIP and a CT from the very first public beta of CS.

Almost Water
It's sort of water, but not really. And also it's a standard model so it can be placed anywhere! Each of the three included model has a subtly different wave animation. Experiment and find the best one for your scene. Try overlapping Skin 0/1 and 2 together for a nice effect that looks similar to the official TF2 water!

Left 4 Dead Beta Survivors
Splinks' restored versions of the early Turtle Rock-era L4D1 survivors, hexed to work as separate models in SFM without overwriting anything. L4D2 content is required.
