33 original upstairs and downstairs (17 downstairs and 16 upstairs) poses for G3F and G8F and their mirrors.
Height of stairs steps used to create the poses: 17.79 cm. Depth of the stairs steps used to create the poses: 27.42 cm. I used standard architectural stairs dimensions.
The poses will need adjustements for other stairs dimensions.
Characters different from the base G3F and G8F could need pose ajustments.
