Free 3D Model

I recently updated my 3D Coat program to 2021 release
I decided to test it for Retopolgy via decimation with simple and complex objects to use in UE5!
I make block object in blender for complex object and turn it to 10M high poly mesh and some model made from high poly mesh in 3D coat and extrude some shape on it then I used Retopo Via decimation and set decimation to 99.96 to change 10M high poly mesh to 8K ~ 4K poly mesh without loosing detail ( I think I can go far more than 99.96 ) .
Dirt and Cracks in some model added in low poly paint room with normal map and some of them have a high poly crack detail.
Texture : 4K
