HammUEr, a Hammer/Worldcraft map importer for Unreal Engine

What is it?
HammUEr is a (currently Windows only) plugin that lets you build your levels with Valve’s [FONT=Lucida Console]Hammer Source map editor (VMF), [FONT=Lucida Console]Doom3’s DoomEdit (MAP/PROC) or a [FONT=Lucida Console]Quake-based map editor like Radiant, Jackhammer or 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/MTR(D3)/SHADER(Q3)/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 polygons 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.

Use overlays and decals? HammUEr will also import those for you.

I’m not even close to done adding features, so stay tuned.

Where do I buy it?
Go to itch.io or Gumroad.

[CENTER]But what about the Marketplace?
Epic has decided not to carry the plugin for various reasons beyond my control.

Still confused? Maybe these tutorial videos will help.

With thanks to @JoeWintergreen](http://twitter.com/JoeWintergreen) for the video and screenshots.

The best thing.

So bit of a question or two -

  1. Are collisions maintained during the export process between hammer and UE4 or do I have to set the back up in Unreal 4 or 3D Modeling app?
  2. Can I export from the awesome TrenchBroom Editor to Unreal 4? Are additional formats supported beside .VMF?

Looks super cool and very useful,

Also In B4 Half Life Remake in Unreal 4 :smiley:

  1. Currently, it sets the meshes to use complex as simple (so per poly) collisions when importing them, which should be fine for most of the simple brushes.
  2. Not at the moment, but other map formats could get added in the future. I might take a look at what trenchbroom produces soon-ish.

AMAZING! I need this right now! Great job!! :smiley:
Any ETA for release?

I’ve been testing this, took most of those screenshot above :slight_smile:

Right now to get a map from Trenchbroom into UE4 with HammUEr, this would work

-save it as .map
-open it in something like Jackhammer
-save it as a Half-Life 1 .rmf
-open it in Source engine Hammer
-save as .vmf

and then it would comfortably import into UE4 via HammUEr.

If you have a .rmf or .map the hl2 Hammer will open them without taking that long route

Coming from Source to UE4 this is great but one Q hammers units are inches and UE4 is cm does this plugin compensate for that or must you scale the imported ue4 file by 2.4 ?

Alright Awesome thanks for the tip :slight_smile:

this appears to be a rather excellent rendering time saver. i might be interested in learning. thanks for the trailer. very intriguing.

.rmf, yes, but Source Hammer chokes on most Quake .maps.

There’s a setting for that!

“Scale conversion” is number of Hammer units to one meter in Unreal (I think. Turfster might correct me).

As far as I know the scaling would be 2.54, not 2.4.

ah cool :slight_smile:

For those who don’t know yet, ProBuilder is a tool for Unity that lets you create and edit meshes (brushes) in a similar fashion to Hammer and a UE4 version is already in works. It would be a whole lot easier to do any sort of edits within UE and export the VMF than to edit in Hammer and reimport for any minor tweaks. Having a way to export the imported VMF back to VMF would be fantastic for this use.

Amazing!, i have many old maps done in the hammer era ( 2004 - 2007 ) :stuck_out_tongue: so looking forward to port over some of that work to UE4, hammer was amazing for quick level blocking :slight_smile:

As soon as I get through the submitting process with Epic and they start actually selling plugins, I guess.
All I can suggest is that you let them know how badly you want this to happen :wink:

As JoeWintergreen said, you can set your import scale on the settings page, which is based on 1 meter, so if you originally worked in inches, you’d use not 100, but 39.37

A Question about optimization -

Does HammUEr respect no draw textures? As in it will export the faces with a texture but ones with no draw will not be exported?

Yes it does.

Cool!

So, first version of Quake .MAP support is in my current test build.
Geometry is importing fine, need to finetune texturing.
