Axyz Design (acquired by Chaos in 2023) is a developer of photorealistic 3D scanned digital humans, volumetric 4D animated people, and anima—a crowd simulation application for architectural spaces [1][2]. From massive airport terminals and transit hubs to boutique retail interiors, Axyz Design equips visualization studios with realistic, interacting human populations that reduce the uncanny valley and add lifelike motion into commercial projects [2][3].
⚡ Platform At a Glance: Axyz Design & anima
The Evolution of 3D Humans in Architectural Visualization
For decades, populating architectural scenes was one of the most frustrating bottlenecks in computer graphics [2]. Studios were forced to choose between flat 2D billboard cutouts—which failed in camera rotations and dynamic lighting—or generic, wooden 3D character models with stiff posture and plastic skin. Axyz Design addressed this challenge by developing optical photogrammetry capture rigs dedicated exclusively to clothing wrinkles, natural posture, and multi-angle skin textures [2][3].
The metropoly catalog is divided into three distinct technical tiers designed to optimize memory and rendering resources across diverse project scales:
- Posed 3D Characters: Ultra-high-resolution static scans (up to 8K PBR textures) frozen in natural stances—such as reading a phone, waiting on a platform, or sipping coffee. Ideal for foreground still images where zero motion blur is required.
- Rigged & Ambient 3D Characters: Fully articulated bone rigs paired with subtle micro-movements (breathing, weight-shifting, conversational gestures) or full walking cycles that blend seamlessly into camera dollies [2].
- 4D Digital Humans: Volumetric video captures where geometry and texture stream at 30 or 60 frames per second. Unlike skeletal mesh rigging, 4D capture preserves natural cloth dynamics, secondary muscle deformations, and authentic facial expressions as actors navigate space [4][5].
anima 5: Architectural Crowd Simulation Architecture
While individual character assets are valuable, coordinating hundreds of moving pedestrians across multi-level architectural plans requires advanced pathfinding. anima functions as an intuitive standalone simulation engine that communicates directly with DCC applications via real-time bridges [2][3]:
- Path and Area Vectors: Artists import CAD floorplans or OBJ/FBX collision geometry and draw spline walkways. anima automatically calculates collision avoidance, walking velocities, and social distancing intervals.
- Multi-Level Navigation: Pedestrians navigate complex geometric transitions including stairs, escalators, moving walkways, and inclined transit ramps without manual footstep planting [3].
- Spatial Group Behaviors: The simulation engine differentiates between solitary commuters, walking couples, and clustered conversational groups seated on benches or gathered around kiosks.
- Chaos Ecosystem Integration: Following Chaos’s acquisition, anima scenes stream directly into Chaos Vantage, enabling instant GPU ray-traced walkthroughs of populated urban plazas without hours of pre-baked rendering [1][5].

Technical Diagnostics: Optimizing anima Pipelines
Symptom: The anima crowd animates properly in the standalone interface, but in 3ds Max the characters appear in a frozen rest pose or fail to render in V-Ray GPU / Vantage.
Solution: Verify that the anima project has been exported with Pack & Bake active. In 3ds Max, confirm that the anima Live-Link object is pointing to the active `.anima` cache directory, and set motion blur modes to Geometry Samples = 2 to ensure velocity vectors are interpolated correctly across frame boundaries.
Symptom: Populating an expansive plaza with 500+ scanned characters causes GPU rendering memory spikes and crash-to-desktop errors.
Solution: Utilize anima’s automatic LOD (Level of Detail) settings. Enable proxy display in the viewport, restrict 4K/8K PBR textures to characters positioned within 15 meters of the active camera frustum, and configure background crowd paths to use low-poly ambient walkers (under 10,000 polygons per character).
Symptom: Skeletal deformation overhead severely degrades frame rates when bringing large anima crowds into real-time UE5 levels.
Solution: Convert background rigged walkers into Vertex Animation Textures (VAT) or use the anima Unreal Live Link plugin’s native instancing pipeline. Because Unreal Engine 5.1+ supports Nanite for programmable rasterization, ensure characters beyond foreground interaction are switched to static VAT meshes driven by GPU instanced world position offset.
Pros & Cons
✅ Strengths
- Industry-standard crowd pathfinding designed specifically for architectural spaces.
- Direct Live-Link connectivity with 3ds Max, Cinema 4D, Maya, and Unreal Engine 5.
- Seamless real-time ray-traced rendering integration within Chaos Vantage.
- Extensive diversity of demographics, formal business wear, casual attire, and uniforms.
- Volumetric 4D digital humans deliver authentic cloth simulation and natural locomotion.
⚠️ Considerations
- High hardware requirements for large 4D volumetric scenes with uncompressed textures.
- Subscription pricing structure (anima ALL) is optimized primarily for commercial production studios.
- Live-Link plugins require careful version matching between host DCC and anima updates.
