Some of its features are:
- Extracting embedded content (protected maps may cause errors)
- BSP analysis
- Support for processing multiple files at once
- Convenient BSP file Drag & Drop
- Much more!
If you want decompile a map ( confirmed in Counter-Strike: Global Offensive ) and have error models. It can happen because materials and models are packed inside the BSP map. To solve this issue, go to the tab "other" and ensure "Extract embedded files" is ticked. Then, after completion you should drag the folder that appears in the same path as the new .vmf appears and drag everything to your game folder and then restart hammer.
