Level Design

Warning:Hammer Editor uses Path Tracing to bake and preview lighting. See the System Requirements listed below before you start creating levels for Counter-Strike 2.

Note:Most of the stuff here are placeholder taken from Half-Life: Alyx Workshop Tools for now. Not all pages are fully created yet.

Getting started with CS2's Hammer Editor Todo: Replace & Move all links from "Game Name Workshop Tools" to "Source 2/Docs/", as long if the contents of the page itself applies to other Source 2 games.

Hammer Minimum Specs

Hammer now leverages GPU-Accelerated raytracing to both preview and bake lighting for Counter-Strike 2 maps, drastically speeding up compile times, even on lower-end hardware. As such, a GPU capable of raytracing is now required for Hammer to be fully functional.

GPU Minimum Specs:

• Nvidia GeForce RTX 2060 (or Quadro/Titan equivalent)
  • Note:Although some GTX 10 and 16 cards do support GPU-Accelerated raytracing, Hammer doesn't support GPU-Accelerated raytracing because of a lack of RT cores.
• AMD Radeon 6600 XT (or other RDNA 2 cards)
• Intel Arc series (tested on Battlemage)

GPU Recommended Specs:

• Nvidia GeForce RTX 2080 Ti+ (or Quadro/Titan equivalent)
• AMD Radeon 6800 XT+ (or other RDNA 2 cards)
• Intel Arc series (tested on Battlemage only as of Jan 5th, 2025.)

Note:-lightmapcpu was removed with the Armory update; CPU compiling is now completely unavailable.

Hammer - Known issues

Bug:On some systems, running Counter-Strike 2 with Workshop Tools, will cause the memory usage to increase abnormally (memory leak).1

Workaround:Launch CS2 Workshop Tools by going to CS2's bin\win64 directory and launch csgocfg.exe with -steam -retail -vulkan. However this will disable GPU Path Tracing option in Hammer.

Hammer - Fixed issues

Bug:Since the Armory Update, a newer version of the Nvidia Studio driver may cause tool crashes when trying to preview lighting or compile a map using Path Tracing. If you are experiencing crashes, you can try the stable version of the driver: Nvidia Studio 561.09 (Tue Sep 17, 2024).

Confirm:RTX 50 series graphics card has been released, and it only support new driver. Is there any other workaround for these card, or whether if its not affected on RTX 50 series?
