# Daz 3D asset support for Bevy Engine



## Summary



This project comes in a few parts:



* `daz_asset_types`, a standalone crate providing faifhful Rust representations

  of the [Daz 3D asset file formats](http://docs.daz3d.com/doku.php/public/dson_spec/start)

* `bevy_dqskinning`, a standalone Bevy Engine plugin that implements

  [dual-quaternion skinning](https://users.cs.utah.edu/~ladislav/kavan07skinning/kavan07skinning.pdf)

  via a `StandardMaterial` extension

* `daz_bevy`, a crate providing plugins to load and spawn Daz 3D assets into a

  Bevy Engine application



This project is a very early work-in-progress and not yet available on

crates.io. If you'd like to see it come to fruition faster, pull requests are

welcome! (TODO: Write a contributors' guide.)



## Why?



Unreal Engine has MetaHuman, and Unity has the Digial Human package, but as it

currently stands, if you want high-fidelity character models in Bevy Engine, you

essentially need a team of highly skilled artists and engineers to create them

from scratch.



It's my opinion that Daz 3D's impressive core technology, huge marketplace

ecosystem, and reasonable prices and licensing terms make it a promising

candidate to fill that gap. Unfortunately, Daz Studio's export capabilities

leave a little something to be desired — while Daz offers reasonably

well-supported "bridge" plugins for Unreal Engine and Blender, I don't know of

any direct pipelines available from Daz to glTF, and even if they existed, there

would still remain quite a bit of work to get all the bells and whistles working

correctly in Bevy Engine.



## Tentative Road Map for `bevy_daz`

- [x] Get the base Genesis 9 figure loading in Bevy Engine with UVs, joints, and

  skin weights

- [x] Implement dual quaternion skinning for more faithful mesh deformations

- [ ] Translate IRAY material definitions to Bevy-compatible equivalents

- [ ] Implement corrective blend shapes and flexions for 1:1 mesh deformations

- [ ] Support "shaping" morphs for custom characters designed in Daz Studio

- [ ] 1:1 support for importing saved Daz Studio scenes as Bevy Engine scenes
