Hi. I am new user of Poser12. I have a question.

I want to make the movement of the human model in detail.

For example, breathing.

 When a person breathes, the chest moves up and down.

I tried enlargement/reductionon the chest of an existing Poser model.

But, because the entire chest part (Tosro) is deformed, not only the chest but also the back will swell.

I just want to transform surface of the  chest up and down

Is there a way to change the surface of the chest like this?

Also, I want to control the surface fluctuation with the um order.

Is it possible to specify and control the amount of fluctuation at the um orderl with Poser? (For example, coordinates)

If it is on the mm order, is it possible to say, for example, "variate by 1 mm"?

Thank you.

Lesson 16: Custom Morphs & Magnets (renderosity.com)

You could look at the above link to learn about morphs and magnets.  The basic functionality has not changed that much.  Trying to explain it will be hard if you are not familiar with how Poser works, and it is best t try and follow along.  In a nutshell you will either use the Morph brush to move the part of the chest out (the expand of breathing) or use a magnet to move the parts out, and then you will have a dial that you turn up and down along the timeline to make appear to be breathing

Thank you for reply!

I will try this method.

Thank you.

About the precision, in general preferences / interface you can choose millimeters as your display unit. Poser has some measurement tools too (Poser Reference Manual> Building Scenes> Props> Creating and Using Measurement Objects> Line Measurements). Maybe you can use that while working with an orthogonal camera view, to achieve precision.

Thank you for teaching me.

Thank you for your kindness.
