Advanced HISM

Description: This Unreal Engine Function Library enables per-instance material changes for HISM (Hierarchical Instanced Static Mesh) components—something that is not natively supported in Unreal Engine.

To work around this limitation, the library provides a set of utility functions that streamline the process. It allows you to quickly duplicate an HISM component, assign a different material to the duplicate, and seamlessly transfer selected instances between components while preserving their exact transform (location, rotation, and scale).

From the user’s perspective, it appears as though the material of an individual instance has been changed. In reality, the system removes the instance from the original HISM component and recreates it in another HISM component with the desired material, maintaining identical positioning and transformation.

Also with helpf of this Function Library you can replace HISM Instances with Static Mesh Components or Child Actor Components to make them interactive.
