Convert Scene to Model
If you need to convert a scene to a single model (or large sections of a scene) you can use the Convert Scene to Model utility. The tool is found in Wall Worm > Wall Worm Model Tools > Convert Scene to Model. In many cases this tool is used for clustering props (to reduce prop count in a scene).
When you run the function, the tool can collapse the targeted objects (scene or sub-selection) into a single object, delete most tool texture faces, weld vertices and create a WWMT Helper for the object to export as a model. This tool was intended as a replacement for Propper (converting imported VMF files into models) but can be used on arbitrary scenes. The video below used this tool to cluster rocks to the landscape.
Converting Scenes to Models
Converting a set of props into a single prop is simple.
Simple Steps for Converting
- Open Convert Scene to Model
- Select Objects in Scene to convert
- Set the Convert option to Convert
- Set relevant options (like Weld, Delete Faces with Tool Textures, Convert Models and Generate Collision Hull).
- Click Do It.
- Review your results and click Accept Last to move onto next object.
- Repeat on next set of objects to convert
Exporting the Model(s)
For the most part, exporting the model itself should be as simple as selecting the WWMT Helpers generated in the scene and clicking Wall Worm > Wall Worm Exporters > Export WWMT To Source Models.
Explanation of User Interface
Choose the objects to convert: Selected Objects or the Entire Scene.
- Skip Hidden
Skip all hidden objects in the new model.
- Skip Import Layers
Skip objects that are part of hidden Utility Layers that WW creates during QC imports.
- Convert Models
Include model props. When off, ignores objects of the WallWormMDL class.
- Skip Dynamic MDLs
When on, will skip models that were not compiled with $staticprop.
- Convert Displacements
When off, skips displacement objects. If you convert displacements, you will need to do extra work for baking blends.
- Convert Untagged Geometry
When on, will use any geometry in selection/scene unless filtered with displacement/model options. When off, only objects that would normally export as brushes (and MDLs/displacements) will get collapsed.
- Skip Import Layers
The function will skip objects that are put in standard utility and import layers created by WW.
- Delete Faces with Tool Textures
Delete the faces of the model with textures that have the word "Tool" in them.
- Weld Verts
Weld the vertices of the model.
- Create WWMT
Generate a WWMT Helper with the resulting model to re-export into Source
- Pivot to Origin
Place the model's pivot at the world origin.
- Illumination Origin
Set options for where the illumination origin should be.
- Create Collision Hulls
Generate a Hull from each Element of the model. Warning: this can be slow with large scenes!
- Delete Objects that Cannot Convert
Delete skipped objects from the scene. Do not do this if there are objects you need to keep like entities.
- Union Parts
This function requires the Carver plugin to be installed. The tool will remove all intersecting faces of the resulting model.
- Use Culling Objects
This setting will cull away any geometry that intersects with the culling objects. Uses include removing faces of props that are hidden under a displacement, etc.
