[Zbrush] Is there a maintain form brush?

Binxx

I haven't used Zbrush in a while, and I was wondering if there is a maintain form brush. It seems like I've been using quite a bit of alphas however the brushes keep shrinking the mesh, is there  by chance a Brush that could maintain the form of the object while I'm sculpting it? or something to inflate back to original shape while maintaining detail? (currently working in layers) (I tried the morph brush on the zero but it kills the detail).. Is

On the alpha pallette, try enabling "Surface" for maintaining the bigger forms of the sculpt more or less untouched. In the documents it's described like this:

"The Surface button mode automatically defines the best middle gray value for your alpha. It allows you to add details from the alpha to your sculpt without destroying details already on the surface."

Or you can play with the "MidValue" setting on the Alpha's Modify sub-pallette, where you control the middle gray value yourself.

Both have been incredibly helpful. Thank you
