Wish list item - Surface Pressure / Tension Sensitivity?

ZBrush Usage Questions
#1

I would like to see a feature in ZBrush that would allow you to turn on or off an object’s reaction to pressure or surface tension.

Example - right now if you have two spheres and you push them toward one another they simple pass through each other. With the feature I invison, turning Pressure Sensitivity on would make the two spheres react as if they were water balloons and there shapes would change as a result of being pressed together. The amount of deformity could be controlled with a slider like many of ZB’s other features. This would be a boon for making flesh react to surfaces and objects allowing it to deform in a realistic fashion.

Is this type of technology already available in another modeling package?

I believe this is called Soft Body Dynamics in Maya at least.
I would like to see it too one day in zbrush but don’t think we will for awhile, I’m really hoping the new zspheres will maintain volume when compressed.

I looked around online to try to find a close example of what I am referring to, this is the closest I could find - the two lobes/cheeks display the crease of surface tension created by the two objects colliding: http://www.lifecast-art.com/True-Love_heart.jpg

Spaceboy, I did a search for the feature you described in Maya and that looks like the functionality I’m talking about, though I only found a few examples.

I’m excited about zspheres II and can’t wait to play around with them. ZB is getting closer to matching real-life sculpting and I was holding my breath waiting for a armature/rigging system. Having soft body dynamics in ZB would just make it the perfect modeling program (at least for me) :+1:
