(Following information is from Mr.Kutsugi's diary of his web site.)

Terai Yuki (Poser version) is originally made by Mr.Kutsugi in 3dmax format.
And e-frontier US converted to poser figure and released the Low-Porygon model.
Then e-frontier US released Hi-Res version without notice to Mr.Kutsugi.

But Mr.Kutsugi does not satisfy the quarity.
Now, Mr.Kutsugi, Billy-T, and Mask-da are working for fixed hi-res version.
They are re-building JPs, materials, groups, UVmapping and more.
So the new version will be released in near future.
