Hammer Resource Usage

This article needs more links to other pages (since January 2024). You can help improve navigation by adding links to related documentation, such as entities or tools.

The Valve Hammer Editor uses lots of resources when loading models and textures, easily 400-500 megabytes when the full texture browser is loaded. This is not a bug or a "memory leak". Memory usage should plateau after that amount.

Usage of the model and texture browsers are the largest source of increased memory usage. When using these browsers, the application is forced to load a very large amount of raw source content.
