Sample Scene and ARKit integration.
A sample scene project file is provided with an example of how to set up the plugin and blueprint for using blendshapes with ARKit and animation, using Unreal Engine integration with ARkit. Download here.
The project includes the Reblium SDK. You can either copy the plugin from there to your own project or use Unreal Engine to migrate your characters.
How to use the sample scene:
Step 1
Simply load your DHS file, then double-click the ARKit Blueprint located in the Asset > ARKit folder. It will prompt you to choose a skeleton; select the skeleton of the character you wish to apply the animation blueprint to.
Step 2
After selecting skeleton, save and close the ARKit animation blueprint.
Open your character blueprint and select the SkeletalMesh component. In the Details tab, under Animation > Anim Class, select the ARKit animation blueprint assigned to your character skeleton from the list.
Step 3
Compile and save your blueprint with the ARKit assigned, your character should now already move using ARKit inside the blueprint.
Note: In the Livelink App, the “Subject Name” in settings, needs to be “Reblium”. To match the name in the blueprint. The sample blueprint:
