A highly realistic fish 3D model created based on real-world measurements and direct observation.
Designed for both realism and usability, this model is suitable for games (Unity, Unreal Engine, etc.), simulations, exhibitions, video production, and educational use where accurate scale is important.
This is a “real-world standard” model created through direct observation and measurement of actual fish.
In the March 2026 update (v1.2), real reference photos are included with every model, and no AI-generated images are used.
The model uses 2K resolution textures for high-detail representation.
Most models use a single texture for ease of use and performance (long-bodied fish may use two textures).
Shape keys (blend shapes / morph targets) are pre-configured for the mouth, gills, and fins, enabling quick and easy animation without any additional setup.
You can view the shape key (blend shape) animation in the preview video.
(Note: Rigging and animation are NOT included.)
The fins use the alpha channel of the albedo texture (PNG).
Depending on your rendering environment, alpha blending or alpha clipping may be required.
Double-sided rendering is recommended for fin materials.
The pectoral and pelvic fins use a single-plane structure optimized for transparency.
Backface plates are included as separate objects in the Blender file for flexible use.
We offer "SampleFish" as a free separate product for compatibility testing, allowing you to check whether it works with your application.
