Using RMB just as you would move clothes, you can now move the arms to different positions.
3 different positions can be accessed with just 1 click and hold of RMB, with the far poses accessible by moving the mouse extra far.
I've taken a break from my month of working on the Rear View Pose to work on Arm Poses for a week. Much of the work was in making the bones of the 2.5D model work with the clothing move in a realistic way. Modeling stuff gets much more complicated when the clothes are basically their own character too.
Deepest Massage uses multiple layers of animation on 2.5D bones to have one continuous animation where each body part interacts with each other in a way that looks realistic.
What this means for the Rear View is that you can smack the cheeks and grab them and move them around, and you'll see the coochie and butt and the surrounding skin move and jiggle as it would in real life.
I will apply these "physics based" interactions to the rest of the game, but for now the rear view will be a good contained place to start. I have the bones rigged, and have the shading, jiggle physics, and code left to do. I hope to get these to you as soon as possible!
