Lazy3D’s Fauna Master Pro is a content-and-simulation add-on that populates Blender scenes with everything from insects to bears, all running on real-time logic. It’s sold through SuperHive and marketed as a “smart asset-and-simulation system”, which essentially means it bundles animated models and behaviour nodes in one package.
Rather than relying on baked caches, the system responds live to changes. You can scatter swarms, flocks, or herds, then nudge sliders and watch them instantly dodge obstacles, follow curves, or panic when something moves too quickly. The goal is to skip the usual setup time and instead watch your scene crawl, flap, or swim into life right in the viewport.
150 Species and Counting
The core library holds more than 150 animal species, sorted roughly into insects, birds, land animals, and fish. Each group comes with its own pack of geometry-nodes-driven motion systems. There are built-in rules for avoidance, attraction, goal-seeking, curve following, and something charmingly called the Scared state — a behaviour that sends agents fleeing when they detect sudden motion, loud sounds, or potential predators.
Behaviour modes can be switched at will. A butterfly can crawl, fly, or do both, and swarms can pivot between movement types without rebuilding the setup. Because the system calculates in real time, users can edit flight paths or collision boundaries while playback runs.
For large populations, a proxy preview mode replaces models with point clouds to keep viewport performance usable. Idle-state agents can also fill backgrounds with subtle motion, keeping scenes alive without burning GPU cycles.
Heavy Assets, Light on Fur
Fauna Master Pro is a heavyweight in download size if not in polygon count. The Lite version weighs about two gigabytes, the Base about seven, and the full Pro edition about ten. The assets themselves are optimised for mid- to long-range shots. There is no particle-based fur and no attempt at extreme mesh fidelity, mainly to keep real-time simulation within Blender’s limits.
The models range roughly from ten to eighty thousand polygons. That keeps motion stable enough for complex flocks while avoiding the molasses effect of ultra-dense meshes. Lazy3D notes that collisions can become unstable in high-complexity scenes and recommends using low-poly colliders for smoother results.
Behavioural Limitations
As with most geometry-node systems, some realism stops at the API. The add-on cannot yet switch animation states dynamically — a wolf cannot choose between walking and running based on speed. Instead, Fauna Master Pro randomises three animation variants per species with different start offsets, giving the illusion of natural variation without perfect synchrony.
Exporting simulations to Unreal or Unity is currently unsupported, so Fauna Master Pro remains a Blender-only playground. Fish also have a minor quirk: their “waving” motion requires Blender 4.4 or higher, as earlier versions lack the required node function.
Setup: Five Files and a Checkbox
Installation follows the usual Blender ritual. Drop the base add-on ZIP into the Add-ons panel, enable it, and a new “Fauna Master Pro” section appears in Preferences. There you can install the four content packs — Animals, Birds, Fish, and Insects — each distributed as a separate archive.
The add-on allows two installation modes: automatic (to Blender’s add-ons folder) or manual (to a shared library folder). The latter is the better option for studios running multiple Blender versions, as it avoids duplicating the ten-gigabyte asset cache across machines.
Once installed, a new panel appears in the 3D View where animals can be scattered, grouped, or directed along curves. Lazy3D also provides a brief installation video and PDF manual.
Practical Use
In production, Fauna Master Pro’s biggest strength is speed. Need a distant forest that doesn’t look dead? Populate it with birds and squirrels in a minute. Need a drone shot over an ocean? Fill the water with schools of fish. The ability to iterate behaviours without pre-baking saves time during look-dev and layout.
Yet the system has clear limits. Collision accuracy depends heavily on geometry density, and dense environments can make the simulation unstable. Since the logic can’t be exported, the add-on is suited mainly for rendered shots, not interactive environments. Artists after photoreal close-ups will also find the asset fidelity modest: these animals are made to move, not to star in macro shots. In short, Fauna Master Pro is best viewed as a fast, flexible prototyping and background-population tool rather than a final creature solution.
Pricing
Fauna Master Pro is sold in three tiers, each scaling in both species count and price. The Lite edition costs $14 and includes 35 unique animals, or 46 when counting animation variants. The Base version, priced at $34, builds on that with 73 more species for a total of 108 unique models (153 with animations). The Pro edition, at $70, bundles the full zoo: 217 unique assets or 287 once animation variants are included. All versions share the same core simulation features; only the library size changes. Given the file weights—two to ten gigabytes depending on edition—storage, not wallet, may become the limiting factor.
The Verdict
Fauna Master Pro turns Blender into a small wildlife reserve. It’s surprisingly elegant for what could easily have been a gimmick: real-time agents reacting to collisions and curves actually work well within Blender’s geometry nodes. The large species library makes it tempting for previs, nature shots, or environment work where believable movement is more important than anatomical detail.
It’s not production-ready in the sense of robust pipeline integration: simulation export, animation state switching, and close-up detail remain out of reach yet. But as a way to populate a quiet scene or test camera motion against moving wildlife, it delivers a lot of motion for its bytes. As always, test it thoroughly before committing it to a final sequence. Real-time magic tends to behave differently once render time comes calling.
