Update

○ Added support for Character Creator 3.44

○ Support for Export USD (Omniverse) > Send to Server which sends the current file directly to Omniverse Nucleus Server.

○ 60, 30, and 24 fps options are available for Export USD > Export Range > Motion FPS.

○ Export USD > Post Effects offers several basic presets, which can be further adjusted under Create > Render Settings > Post Processing.

○ Export USD > Export Current Frame as Static Mesh for Refinement is provided to convert bone-skinned content to static meshes for subdivision in Omniverse (the bones will be removed).

○ The export will output the main USD file along with other dependencies, such as a light, material, and motion folders, which will contain the associated MDL materials and textures.

○ Character related animations will also export to Omniverse, including the following data sets:

■ Transforms, Motion Clips (supported in v3.41).

■ Expressions, Visemes¹ (enhanced in v3.44).

■ MotionPlus data with Accessory animation exported from iClone (enhanced in v3.44) .

■ Spring Effects² and Physics Rigidbodies² (enhanced in v3.44) .

1. Does not include Viseme Voices.

2. Spring Effects and Rigidbodies are baked into keyframe animations. Once they are brought into Omniverse their physics settings can not be adjusted.

3. Does not include visibility keys, material animations, and sound.

○ PBR, Digital Human*, and SSS shaders sent to Omniverse from iClone and Character Creator will map corresponding textures and material attributes accordingly.

*Digital Human Shaders include Skin, Head, Teeth, Tearline, and Eye Occlusion.

Special notice 1: Omniverse Digital Human and SSS shaders only support RTX Path-Traced mode at this time. Export USD (Omniverse) > Material Render Mode must be set to RTX Path-Traced for materials to map correctly to Omni-DH and Omni_SSS shaders. If Realtime Mode is selected, then every material will map to Omni-PBR shaders.

Special notice 2: When a Digital Human character with SSS shader is exported in RTX Path Traced mode into Omniverse and the render mode is changed to RTX Real-time within Omniverse, then the SSS shader will not take effect and the Digital Human's material will change to pure white or pure black without any of the original material attributes and details.

Special notice 3: White lines can appear when Shader > Subsurface Weight is set too high, or when an improper SSS map is used, such as a solid white texture.

○ Inconsistent translations and rotations with IBLs sent to Omniverse.

○ Exported characters containing only face meshes can take advantage of AudiotoFace > Character Transfer > Mesh Fitting Preset, without the need to set up corresponding points on individual meshes

○ Exported characters with teeth, tongue, and dummy objects can perform full talking animations by using Machinima's Pin Constraint and Create Wrap tools. Pin Constraints can tie the teeth to the mouth motions, while Create Wrap can reapply the animations back to the entire character.

*Note: This entire workflow requires the Machinima 2021.2.

○ Support for Export USD (Omniverse) in File > Export menu.

○ Support for Export USD in the Toolbar.

*If the plugin is not installed then a message prompt will appear inviting you to visit the instruction website.

*Does not include physics settings and collision shapes.

*Special notice: The character should be exported with the animation for the best possible result. For example, animation applied from a standard proportion to a smaller character will give unexpected/erroneous results.

○ RTX Real-Time: All Digital Human shaders and SSS materials will use the Omniverse PBR shader.

○ RTX Path-Traced: Digital Human shader Skin, Head, Tearline, Eye occlusion, and SSS will all use the Omniverse SSS shader. This is an overall visual improvement at the expense of additional system resources.

CC Omniverse Connector was developed for Omniverse Create 2021.1. There are some known issues with this version that will be subsequently addressed and resolved with the release of Omniverse Create 2021.2:

* Appearance of line segments with the SSS shader, especially on the nose and jawline with the presence of an HDR enabled light dome.

* Appearance of excessively bright highlights with the SSS shader, e.g. oily lips.

Live Sync real-time automatic updates is a feature that is slated for release in a later version.

* Discrepancies in the light intensity can happen as a result of translating the Multiplier value.

* Mismatch between the IBL dome position and brightness can still occur.
