Valve Hammer Editor

What works

• General editor functionality
• All tools: selection, entity, block, texturing, decals, overlays, clipping, and vertex manipulation
• Displacements
• Soundscapes
• Lighting
• Skyboxes
  
• Saving and loading
• Compiling
• Running the map in TF2

What does not

• 2D views don't update immediately

• To fix this I simply move my mouse in a circle between all the views after making changes or zooming in the 2D views.

Additional Comments

I had to downgrade to Wine 1.8.4 in order to make it work correctly. In new versions of Wine the window doesn't render correctly and all window buttons flicker with a black texture.
