vvmtool

This is the exporter for our extended model format (VVM). It's based off IQM and to some extent is backwards compatible (this was done so that editors capable of displaying IQM files would just work, however it depends on how the loader is written.

These days, you can find an updated version of this tool inside the FTE SRC, however it has grown to become much more than a model exporter and become less portable as a result.

For those reasons, we are preserving our version of the original, extended tool here. It exports plain .IQM files, as well as .VVM files.

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.
