Best option for Octane compatible humans?

[boxfx]

Ive been tasked with adding humans into our 3D product renders (headphones, consumer devices etc) does anyone have any recommendations? The main requirement is that we need to be able to create and adjust the characters hairstyles and colours, facial poses, rigged fingers etc. So a library of scanned people wouldn't be of much use. Essentially an Octane+c4d compatible version of something like Unreal's MetaHuman.

If not, are there any decent rigged characters you can recommend, we'd ideally need to cover all the main bases, so male and female versions of white, black and asian characters.
