vvmtool

These days, you can find an upgraded version of this tool that supports loads more formats in the FTE SRC, however links against more dependencies

For those reasons, we are preserving our version of the original, extended tool here. This is the version that shipped with The Wastes' SDK in 2018.

It will be updated if we make changes to our format, those will also be pushed upstream to FTE's general purpose model exporter tool.

Inter Quake Model & VVM Exporter

This is the exporter for our extended model format (VVM).

It can export both standard IQM files and our extended format called VVM for use in FTEQW.

It's based off Lee Salzman's iqm tool.

Features

Features that the original IQM exporter did not offer:

  • Support for external configuration files for IQM generation (ala studiomdl)
  • Pre-processor for rotating single or all input files
  • Pre-processor for translating/repositioning single or all input files
  • Pre-processor for renaming bones inside a single or all input files
  • Pre-processor for material prefixes inside a single or all input files

Some features that our extended specification (VVM) has to offer:

  • Support for hitmeshes for faster, content-aware collision detection
  • Automatic hitmesh generation
  • Submodels that allow showing/hiding specific groups of the model via the game-logic
  • Support for frame triggered events that can be read by the game-logic (model-events)
  • Level-of-detail range flag for references/sub-models
  • User-defined surface and contentflags per reference/sub-model

NOTE: Using any of the VVM features is not supported in any engine other than FTEQW

The tool's output will let you know if you're outputting an IQM compatible file or not.

Building

Make sure you have a C++ compiler installed and issue:

make

There's a Makefile for mingw cross-compilation as well.

Usage

Please read the vvm.txt file included in this repository for more information.

Contributing

If you're looking for bug-fixes to the existing tool, stay here and post issues and send pull requests if you happen to find bugs!

If you want more specialized features, support for more output formats and the like those should be handled by the tool in FTE SRC as that specializes in that sort of thing.

Any bugs that get fixed here will be checked against the above tool as well.

History

In 2016 when we had our first prototype of The Wastes, we started out using DPM for toolchain related reasons and quickly migrated to IQM. However we needed a better system for handling reproducible output files. The original tool only handled compilation via plain command-line parameters which was not good enough.

The input command file (.qc) syntax is obviously inspired by qdata and other tools such as studiomdl. So if you're familar with those tools you know exactly what to expect.

We then went on and designed extensions that we needed to make the game work, for example a generic model-events system that'd call events in the game-logic when a certain keyframe in the model is displayed.

More complicated things were hitmeshes, for more accurate hit detection of body parts as well as submodels that made the action of shooting body-parts off possible.

We developed this together with David of FTEQW, since this had to be developed in conjunction with the FTEQW builtins that'd later be exposed to the game-logic.

However, the initial extensions to the IQM format in FTE were designed by us; and this is the exporter that was used to make our game.
