This is the Valve Hammer Editor (formerly known as Worldcraft), version 3.4, for editing of Half-Life and Half-Life mod maps.

The most notable change in this version is the change in name to Valve Hammer Editor. The following changes have also been made:



Splitter view layout is now preserved from session to session.

Dialog bars now pop to the top when the mouse cursor floats over them.

No longer renders the 3D views when the editor is not the active application. (This will fix most people's problems with running Hammer and Half-Life at the same time causing the editor to freeze)

Added Copy to Clipboard button to the process window.

Sped up time to bring up the Face Properties dialog when many brushes are selected.

Sped up 2D view scrolling.

Added timed selection of objects by depth in the 3D view when the left mouse button is held down.
Fixed:


Fixed a random spinlock when rendering sprites.

Fixed texture rendering problems with sprites, etc.

Fixed freeze when starting map with sprites visible.

Fixed a crash in the path tool.

Fixed problem with texture shifts being reset when importing old MAP files.

Fixed black brushes caused by clipping.

Fixed a lockup when scaling certain brushes.

Fixed infinite lines in 3D view in vertex mode.

Fixed clipping causing duplicate solids.

Fixed decal repositioning.

Fixed camera angle view bug.

Fixed problem with running compile tools from paths with spaces.
