Prop Libraries

NOTE: Wall Worm now supports native MDL files in 3ds Max 2015+. As such, the Prop Library functions are now considered legacy. For Max 2015+ there is no need for using the Prop Library functions.


Wall Worm has the ability to save WWMT models to a Prop Library. The prop library allows you to re-use your props in future projects in the same manner you would use prop in Hammer.

Prop Library Files contain a WWMT Helper and all the meshes for the model. It also includes a WWMT Proxy with a specific name. This Proxy is generally the target for the World Model XRef when you open the Point Entities Floater. It is used as a XRef Object.

Creating Prop Libraries

You can save your props to the Prop Library via three methods: In the VMF Importer, the WWMT UI and in the QC Importer.

Generating Prop Libraries from VMF

To import props used in a VMF into your prop library, click Wall Worm > Wall Worm Importers > Import VMF or Map . Then click the button labeled Prop Library From VMF File. Now browse to the VMF file with the props. (The QC/SMD files for the props must reside in your modelsrc folders.)

Saving a Prop Via WWMT

After you are completely done with your prop, you can save it to the Prop Library by opening the WWMT Helper in WWMT, opening the Utilities Rollout and clicking the Save to Prop Library button.

Saving Multiple Props Via QC Imports

To import an entire collection of models to the Prop Library, you should first have a collection of QC/SMD files. Generally, these will be in your sdk_content/modelsrc folder. If you want to import all your mod's props, read the article on Unpacking GCF and VPK Files.

  1. Open Max and create New to make an empty scene.
  2. Open the SMD and QC Importer ( Wall Worm > Wall Worm Importers > SMD and QC Importer ).
  3. In the QC Options, check the Save to Prop Library checkbox.
  4. In the Batch Import section, enter a folder filter and/or file filter to limit the props you are importing. Using * in both fields will result in all props being imported--which can take a long time. (You can enter "*de_aztec*,*de_inferno*" as the folder filter, and then only models in those folders will import.)
  5. Turn on Recursive Search.
  6. Turn on Skip Root.
  7. Turn on Delete After Import.
  8. Click Import Multiple Files.

Props are saved to your 3ds Max Project's import folder. They are saved in this format:

#imports/WallWormPropLibrary/FGDFILE/modelpath/modelname.max

The FGD File is the filename of your mod's FGD. For CS:GO, this is "csgo"; for Day of Defeat, this is "dod", etc.
