This is a blueprint tool for Static Meshes based on HISM tech. It’s a three-dimensional array which creates instanced geometry along X, Y and Z axes.

It contains BP_SimpleArray and a few lowpoly meshes to present how it works.

HISM stands for: „Hierarchical Instanced Static Meshes”. It’s highly optimized approach which reduces tris count significally.

BP_SimpleArray works in a procedural way and has features based on instanced geometry randomization. Drag and drop blueprint to the scene, set up a static mesh and material in actor settings and play with array config.

RECOMENDATIONS:

• Convert large arrayed actors on your scene to PLA - this will reduce mouse lag while moving actor on the scene.

• Convert multiple arrayed actors on your scene to PLA - this will greatly reduce drawcalls.
