Reverse Morph Brush

ZBrush Usage Questions
#1

Hi

Apart from switching a Morph Target, is it possible to invert the Morph brush whilst adding things back? So removing things you’ve added just with the brush? I swear there was an option to do that. I figured you’d just hold Alt, but that seems to be smashing into my mesh rather than putting things back before making a stroke with the brush. :-\

I even tried resetting ZBrush, thinking it was my tablet playing up, but it still does it. So unless it’s a problem with an older version of ZBrush that’s since been fixed up…?

Thanks

Is this not possible to do then? Have I just been imagining it?

Hi @DustyShinigami

The Morph brush by default returns the mesh to the state of the stored Morph target. So it isn’t necessary to hold down ALT to remove sculpting added by other brushes, or to re-add features that were removed by another brush.

Or do I misunderstand the question?

Yeah, you’ve misunderstood. :sweat_smile:

I meant, does holding down ALT not undo/reverse the action made with the Morph Target brush? Similar to when you sculpt, you’ll add ‘clay’ on top, and holding ALT will take it away and smash into it. With the Morph Target brush, it’ll gradually revert a mesh back to the original you’ve stored, but does holding ALT not reverse it? So it undoes the change and puts the mesh back to the way it was?

I could be completely misremembering, but I thought that’s what it did.

Thanks

The Morph brush does not support Alt functionality in the way you suggest.

The brush only restores the form of a stored morph target. If you have a stored morph target that contains features that subsequent sculpting has removed, then the Morph Brush will restore those features. If subsequent sculpting has introduced detail that the MT does not contain, the Morph brush will remove it. It will perform both of these action at the same time with a single brush stroke, so it is not necessary to hold down ALT to control the direction of the displacement and this will not produce good results.

The ZProject brush does work in the manner you suggest. It’s possible you may be remembering that?

Ahh, okay. Thanks for confirming. It’s just my memory then. :sweat_smile:

I don’t believe I’ve used the ZProject brush before. So the only way to undo what’s been done with the Morph Brush is to Ctrl + Z? Or use the ZProject brush?

Thanks

The morph brush and the ZProject brush work for different situations. ZBrush projects the detail from another subtool onto the surface of another subtool that overlaps it. It does this along a single direction at a time, so using the Alt functionality does work in the way you suggest.

Just like any other brush, yes. Morph brush restores the mesh to a state that has been predefined either by storing a Morph target, or in more recent versions of Zbrush 2023, by marking an Undo History state. In that case the Morph brush will restore to that marked state.

This may provide more flexibility than working with a MT. Simply mark the blip you want the Morph brush to restore to in a given situation. If an earlier or later history state is preferable, simply mark that blip instead.

Otherwise, you must protect areas of a mesh with masking if you don’t want them to be affected by the Morph brush.

Ohh, so ZProject works like the Project menu tool for projecting a mesh’s details back? Only gradually over a certain area. Hmm. Interesting. I’ll have start making use of it. Thanks.
