For more information about how the deformation of the model is behaving, please check out my latest model done with this mesh: 

This is my personal BaseMesh model I'm constantly improving and working on, having articular joints and an animation-friendly topology at all places. From the finger joints to her hips, chest, and face, you can animate and rig everywhere and get a very satisfying result. 

This particular basemesh has a higher polycount in comparison with the previous model, adding details, further fixes, and increasing the overall polycount density on the face. That way, you'll be able to get a higher fidelity in facial expressions with little to no compromise in the other areas. Some parts, like her chest, were also changed for a better, smoother look right out of the bat.

Some observations:

• Their topology is completely Quad/Tri, so there won't be any shading artifacts and N-Gons in the model.
• The polycount for the whole body is exactly 57.660 Triangles. Eyes/Eyebrows/Eyelashes together are 13.076 Triangles.
• For better results, I highly suggest using the Epic Games Metahuman's Eyes, tooth, and mouth. 
• There is geometry for the inside of her mouth so you can properly place a Tooth and a Tongue inside her head.
• The Body model has UDIM tiles. The first UV space has her whole head, and the second one has her whole body. There is also minimum stretching on the UV, so the density is pretty much even through her whole body. 
• You can use UDIM or a separate material for the Body.
• The model is on A-Pose, at the VERY SAME pose as Epic Games's Echo model.
• This product has a .blend (ver. 3.5), .fbx, .obj and .ztl.
• The .ztl is polygrouped by UV's.

In case you're having trouble with anything, please let me know. 

I hope everyone likes it!
