No inverse kinematics?

That is the most important feature this would make me use this over the good old wooden puppet, which is small (10cm). I.e. it travels with me with my drawing utensils.

I guess I am asking: what exactly is the value proposition?

    What exactly is inverse kinematics? A short search tells me it is something like "if the hand goes in a certain position and a certain angle, elbow and shoulder must go into these angles", is that it?

      Yes. Instead of having to figure out the bone angles one by one you can drag eg a finger and the rest will follow as much as constraints allow.

        Does it just make it easier to get in a position you want or does it give you more natural looking positions as well or any other benefits? It's pretty fun to play with!

          It means that you can lock the end point to a position and figure out the rest of the pose.

          Imagine a character walking with forward kinematics. Every time you move the characters hips , you’d have to rotate the leg joints and make sure the foot doesn’t slide. Remember virtual characters don’t have friction.

          IK lets you lock the foot in a spot so you can animate the body above it without having to spend time matching the foot position.

          In a real world, this is like if you tried to put your hand on a door handle while jumping up and down. It’s easier to keep position when you hold the handle than if you were to just touch it.

            It also means you can move the point and the rest of the joints adjust. Want to make your model walk? Just figure out the foot motion and the rest of the details are calculated based on joint range of motion and limb length.

              Without some extra contraints most full body IK systems won’t give you walking motion. It’ll just be like pulling a doll by its limb.

              You need a proper motion controller on top to actually have realistic walking motion driven by steps.

      Imagine placing the feet on the ground at some location and then pinning them there. Now you can move the hips and the upper and lower legs as well as the knee orientations change to keep the feet planted in the same position.

      regular kinematics derive coordinates from joint angles

      INVERSE kinematics derive joint angles from coordinates

      it's useful when you have a chain of joints and a mug to grab with it

    It's a checkbox in the "..." menu. Off by default for some reason.

Though the internet is for porn, this does not seem to support genital or secondary sexual characteric contributions to a pose. I respect the bold approach but doubt that it will discourage much use of this tool by that community.

    There was a Mac app called Poser which is probably what you want.

look interesting, but not sure price make this worth that

Very cool idea, congrats on the launch!

What's up with the pricing? $7 per month for 'pro' or 20 for pro +. You can buy an actual real life manekin you can use forever for 10. Who's going to pay monthly for this? Who even is the target market.

If you're comfortable enough with 3D meshes to make use of the 3D export function in the paid subscription, you could just download a manekin into Blender and do all this for free.
