This is an UE4 Smart Fur material for CGI, VFX, Cinematic, Cartoons, Short Films, Commercials and Advertising. It is NOT an UE4 grooms based Hairs (so, no physics), but just a displacement based highly customizable and animatable Smart Fur.
Tested in Unreal Engine versions: UE 4.25, UE 4.26. For use with UE 4.26 just Migrate the materials you want from \Materials\SmartFur to your project. You can use this material in versions prior 4.25 too - just copy-paste the base material nodes.
This bear has 33k tris, 16.5k polygons. A large amount of hairs is achieved through UV Tiling of displacement map (has 1024x1024, used Tiling value is 100) + Tesselation Multiplier (used value is 30). You can get my Free Simple Fur material for testing: https://artstn.co/m/3vkv
Material has 73 parameters, and an additional 19 animatable MPC (Material Parameter Collections) parameters (see screenshots above).
Material has two Color maps + two Fill Colors + two Fur Length maps + two Overlay maps, which allows you to create animations of any length, using animatable MPC parameters and switching between different material Instances.
Below is a short video explaining the basic functionality of the material.
The package contains an Unreal Engine 4.25 project that includes:
One Smart Fur material + 7 predefined Instances I used to render the demo video.
Level Sequence + Music track + everything else that is needed to render the demo video.
Movie Render Queue Preset I used to render.
Bear 3D model source file in Blender format, both High Poly (33k tris) and Low Poly (6.8k tris).
All used textures in PNG.
All source files are in the folder SmartFur\ObjectsSources
I used the following post-processing for Linear EXRs of demo video: LUT: Linear to Rec.709 Color grading: Gain to 0.61,0.61,0.61,0.61
