Combine the best of both worlds when working on your 3D game!
The ease of BSP level construction with tried and tested tools can now be married to the power, speed and high performance of the Unreal Engine.
HammUEr (currently Windows & OSX binary UE release only) is a plugin that lets you build your levels with Valve's Hammer map editor (VMF) or a Quake-based tool like Trenchbroom (MAP). With just a few simple clicks, you can have them imported into your Unreal Engine project as a collection of meshes placed in your scene the way you want, where you want. Want to change something? Make your edits in your favourite tool, then save, re-import, and you're done.
During the importing process you can assign materials already in your project to the original material names, or if you have the source images - (TGA/BMP/PNG/JPG)/VTF&VMT/WAD(Quake1 & Halflife)/WAL(Quake 2) - you can import them into UE as material instances based on a template material of your choice, and let HammUEr automatically find and assign the right ones. Don't want certain materials to show? Mark them no-draw and HammUEr will automatically not build sides for them!
Want to start building a level in Hammer with your UE materials for true WYSIWYG level editing? HammUEr can do that by exporting your UE material textures to VMT/VTF combos for easy use in Hammer with one click.
Have Source models you created for your maps? HammUEr can bring them into Unreal Engine for you and places them where they belong.
The current build also supports overlays and decals, and has basic Doom3 support.
I'm not even close to done adding features, so stay tuned.
