Swarm Manager Pro – Mob AI, GPU Instancing & Editor Toolkit

Support | Documentation

GPU Prop Renderer (BatchRendererGroup)

Render tens of thousands of VAT-animated props with near-zero CPU cost using Unity's Batch Renderer Group, or optionally pass a mesh to use the system.

- Zero GameObject overhead after upload.

- Automatic LOD — 3 mesh levels with per-level shadow and lighting control.

- Burst-compiled frustum and distance culling.

- Per-instance color, rim color, animation offset and animation speed

- Per-LOD visuals shader features such as alpha clipping, saturation, contrast, brightness, rim strength, dither, wind influence, shadow color and attenuation, normal map, mask and sub-surface color.

- Lit and Unlit selection per LOD level.

- Runtime visibility control — per instance, range, or all.

- Runtime position updates with partial buffer upload.

- Simple API — Generate, Register, Upload, SetActive, UpdateTransform.
