Hammer What's New
Major new features of the Valve Hammer Editor 4.1
- HDR tools support. High Dynamic Range levels can be compiled and run from Hammer.
- VGUI Model Browser. All new model browser with a full tree control and real-time 3D previewing of model geometry, rendered with the Source material system.
- Enhanced 2D and 3D Views. 2D and 3D views are now rendered with a unified Source materials system, allowing for real-time feedback of transformations in all viewports simultaneously, and much faster rendering of the viewports.
- 2D model and displacement Rendering. Prop models and displacement geometry rendering in 2D viewports.
- Enhanced Auto Visgroups. A larger number of Visgroup categories, as well as an improved interface makes Visgroups more powerful.
- Autosave feature. Creates automatic, numbered backups of maps, with options for when and where backups are created.
- Paste Special enhancements. Provides options for renaming objects when pasted to avoid name collisions with automatic entity I/O fixup.
Major new features of the Valve Hammer Editor 4.0
- Source Engine materials system. Materials created with the Source Engine's advanced shader-based texturing system are properly rendered inside the Hammer Editor.
- Displacement surfaces. A new class of mesh geometry that can be sculpted into different shapes and connected to one another to create terrain and other complex surfaces.
- Input and Outputs entity system. Entities use a new method to trigger and connect to one another, offering a higher level of flexibility and control than ever before.
- Hierarchical VisGroups. Objects can now be in multiple VisGroups, and Visgroups can be organized in a hierarchical manner for easier selection and organization.
- Entity Helpers. New user interface controls that make editing parameters on entities such as spotlights and doors easier and clearer.
- Per-face Lightmap controls. Lightmap density can be controlled on a per-face basis for more control over the balance of visual quality and rendering performance.
- Sound Browser. Built-in browser to hear a preview of sounds available to level designers.
- Non-modal Entity Report and Check for Problems dialogs. Dialogs are now non-modal, allowing for changes in the level and camera controls while using the information in the dialog boxes.
- Smoothing Groups. Per-face control of lighting-based smoothing.
- Find and Replace. Functions to both search and replace for text in any entity name, parameter, input, or output.
- Selection Mode toolbar. A new toolbar to control the impact of groups and entities upon the selection tools.
- Overlays. A new type of texture entity, similar to decals, but with far greater control over how it is applied to surfaces.
