I'm Chris. I've been working primarily with the Source Engine but have also began general hard-surface 3D Art. I'm currently working as an environment and 3D artist at PSR.
One of Black Mesa's more bizarre changes is that Gordon Freeman's arms are evidently very aerodynamic! This is a major pet peeve of mine so I opted to change that.
This is currently unreleased as Black Mesa's workshop is kind of a pain these days.
Unnecesary detail be unnecessary. Nice work.
The golf-free one is way better. Also the materials seems high resolution at first sight, so +1 for that man. ;)
The stock diffuse texture is 2k*1k, and the normal/spec is half of that. Mine uses a 2k*1k diffuse and normal/spec.
