Project New River Contains CUI government controlled assets; for this reason I am unable to provide footage of the project as it would violate my NDA.
Project New River is an Unreal Engine and Unity plugin that allows a user to view and manipulate Universal Scene Description files in an editor space.
The tool currently has the following main concepts that were all internally developed on top of the engines and a DLL built from the USD code base
1. Primitive creation, deletion and manipulation - A user can create new prims and manipulate their transform data at will using the in-engine tools and have those changes saved back to the USD file.
2. Static Mesh Capture - If a user places a static mesh in the Unreal Engine level, the user can then capture that mesh to populate a prim with the USD Mesh description of that object.
3. Textures and Materials - Extending the above capture logic, I created a system to capture the currently applied material to the static mesh and save this material to a textures folder that is local to the USD. The system allows for users to change a material on an already spawned in prim and see that change reflected in the USD on save.
4. Custom Attributes - Utilizing our custom editor UI a user can add custom attributes to a prim and see that data saved to the USD and read back by the UI when a prim is selected. Boolean, Boolean Array, Integer, Integer Array, String, String Array, Float, Float Array, Double, and Double Array are all valid custom attributes.
5. TIFF Import - A user can import a .tiff file and have a static mesh created based on the height data. The asset is then saved to the USD.
6. Primitive Instancing - This feature is primarily a Unity feature and the Unreal Engine side processes the data; as UE handles instancing as a concept differently than Unity. A user can create multiple copies of a static mesh and have that static mesh be instanced. Meaning each duplicate of the mesh reads its mesh description from a mesh cache rather than storing in on the prim; drastically reducing the side of the USD file.
