Hello turbodriver,
I downloaded this mod because of it´s wonderful pose feature. But I have the same problem as somebody before. The pose button doesn´t appear. I am playing the game for a very long time, no installation error through me. I deleted every other mod, I just let the poses, your mod and andrews Pose player in the Mods folder. I used a complete new game file with mods enabled. But the button for the pose doesn´t appear, the rest of your mod works fine.
I don´t know if only certain poses are compatible with your mod, but I guess not. To be sure I installed poses from katverse, who is refering to wonderful whims pose option. Now I really don´t know what is wrong. Before the update your mod worked for me. My Pc has windows, is fully updated and works pretty fine.
I would love to hear from you. Have a nice day.
