You can generate a follicle mask for your skeletal mesh to better blend hair with its mesh surface. The Groom Asset enables you to create textures based on the strands data from your imported grooms. Rebuild the selected groom's build settings from the Groom Import Options.Ĭreate Binding to generate a Binding Asset used to attach a groom to a Skeletal Mesh.Ĭreate Textures for Follicle and Strands using the selected groom.įor more information, see Groom Asset Editor. Right-clicking the Groom Asset in the Content Browser provides several additional Groom Actions that enable you to: You'll be able to:Ĭreate Levels of Detail Meshes that represent strands, cards, or a meshĭebug your groom with different view modes The Groom Asset Editor enables you to manage and edit parts of your groom. Double-clicking the Groom Asset opens the Groom Asset Editor. Groom Assets represent your imported Alembic (.abc) file's hair groom and they are stored in your Content Browser. ![]() Once these steps are completed, you will have an interactive groom that can be used on an attached Skeletal Mesh that is animating.įollow along with the Hair Rendering and Simulation Quick Start guide to perform all these steps in more detail.įor additional details on setting up your Hair Groom for export and import into Unreal Engine, see the Alembic for Grooms Specification reference page that covers the schema that will enable Unreal Engine to import grooms directly. Place your Groom Asset in the World (as an Actor or in a Blueprint).Īttach the Groom Component (Actor) to Skeletal Mesh Socket with Transfer Skinning. (Optional) Create a Binding Asset from the Content Browser for your Skeletal Mesh. Import your Alembic Groom file into Unreal Engine. The flowchart below describes the high-level process of bringing your own Hair Grooms into Unreal Engine and attaching them to a Skeletal Mesh character that can be animated.Ĭreate your Hair Groom in your preferred DCC application.Įxport your Hair Groom as an Alembic (*.abc) file. Under the Geometry category, enable these plugins: Open the Plugins browser window by going to Edit > Plugins. Under Rendering > Optimizations, enable Support Compute Skin Cache. Open the Project Settings by going to Edit > Project Setting. It provides support for multiple hair groupings within a single file, such as head, vellus, beard, eye lashes, and brows, a hair shader and rendering system, and dynamic physics integration driven by Niagara.Īn Editor restart is required for each of these to take effect. ![]() While no standard format currently exists for hair grooms, the groom system provides a naming convention-based scheme using Alembic (.abc) files to ingest data exported from your modeling application. Using the Groom system and tools of Unreal Engine enables you to render each individual strand of hair, which significantly improves visual fidelity of simulated hair in real time. Card based workflows use a large number of flat sheets (or cards) to give the approximate shape, and motion, of a much larger number of individual hairs. Traditionally, hair that has been created for use in real-time engines has been created using card-based techniques, or other similar approximation.
