UE Overview

This is a realistic rat model with 4K maps, rigging, hair. And UDIM UV is applied to the body for more details. The skin map is made separately for a more realistic effect, The model is made with Unreal Engine 5.2, support for Unreal Engine 5.2 and above.

Key Features

Model Details: Total vertex count is 56,746 and polygon count is 59,392, ensuring the model's intricacy and realism.
Textures and Materials: Textures are created using UDIM format and produced in 4K resolution. Textures have already been imported into UE and optimized.
Groom Fur: A complex fur system was created in Blender, and the rat's fur styling has been perfectly replicated using UE's Groom technology, with finely tuned materials.

Usage Notes

Ensure your Unreal Engine version is 5.2 or higher to achieve optimal performance and compatibility
Given the high precision of the model, textures, and the extensive amount of fur, it's suggested for use on higher-end devices.
When importing into your project, ensure to maintain the directory structure to guarantee all linked assets load correctly.
Adjustments to the fur material's brightness and reflectivity may be needed based on your scene's lighting.
