Footnotes

1. Toolset is currently missing support for importing or exporting certain Halo 3 JMS/ASS features such as the W coordinate in UVW. ↩ ↩²

2. Car wheel and prismatic constraints are not exported or imported properly. WIP ↩ ↩² ↩³ ↩⁴

3. JMS/ASS files imported into Blender do not have their triangles connected properly. This means that imported models are improper due to the exporter using vertex normals instead of loop normals. ↩ ↩² ↩³ ↩⁴ ↩⁵

4. Weather polyhedras is currently not exported. ↩ ↩²

5. Halo 2 level imports currently only do the level collision. It does not import any of the other geometry in the level. ↩

6. Imported animations tags currently do not have fixed overlay animations. Compressed animations are also currently not supported. ↩
