sad but true we can't buy but we could make LW Sculptris Dude with Rex in Poser easy.

Poser has rig or morphs.
just cause Rex eyes don't come with rigs ,don't mean we can't rig them are selfs.
just cause he rigged the eyes don't mean ya can't get the same with morphs.

Poser has displacement maps.

Poser has glass or shinny shaders for the eyes.

any thing you see that some one else made you can make to. :)
