No, the AntoniaA figure is included with Antonia 1.0 (not the texture shown in my image). AntoniaA uses the old mapping so that the old textures can be used.  She is identical to Antonia except for the UV mapping. The character in the image is from BE4, called BE4GranTia. She works with AntioniaA.

The figures included in the Antonia 1.0 zip are:

Antonia.cr2  --  base figure

AntoniaA.cr2 --  base figure with old UV mapping, so that textures created on older builds can be used.

Antonia-lo.cr2 and AntoniaA-lo.cr2 -- low resolution versions of the above two figures.

Textures that work with AntoniaA.cr2 & AntoniaA-lo.cr2:  BE4Celene, BE4GranTia
