This needs fixing

ZBrush Usage Questions
#1

This is a problem that I have as I sculpt. I am constantly using my standard brush for folds and as I am brushing up to another subtool, my nice fold ‘crimps’. I fix this by turning on transparency when I am sculpting near subtool ‘seams’.

But it is unnatural and cramps my style to constantly turn on and off my transparency. And I thought, wait, why WOULD the brush crimp by default, is there a good reason for it? I can’t think of one, nor could the artists around me.

Can anyone think of a reason one might need the standard brush to be affected by an inactive subtool? If not, could this be fixed so that the brush acts as if transparency is on? This way I can sculpt more like a traditional artist and my workflow would be faster.

Any thoughts? Thanks
Here is an image of the shoulder area of a jacket, where I baloon out the material and the like. To butt up the subtools ‘tightly’ I have to use transparency.

I think what’s happening is that there’s a crease where the two SubTools meet. This crease is meant to keep the brushes from pulling the edges apart. But that’s creating a problem for your particular workflow. Have you tried removing the crease?

Oh no, there is no crease.

Take two subtools and butt them up against each other. On the active subtool use standard brush, int 25, and draw a stroke into the inactive subtool. The stroke will deform as it hits the inactive subtool.

If you turn transparency on, the stroke will continue cleanly as if the inactive subtool is not there at all.

When sculpting with many subtools that include clothing sections, pockets, patches, etc, I would hope that the standard brush can be modified so that it is not affected by inactive subtools.

Here is a picture of an example, no creases, simple polyspheres.

Hi, bLawless.

Are both subtools set at the same resolution? Different resolutions might cause interference.

Snark, no, same resolution. I made the image/test as simple as possible. The only brush that is not affected by an inactive subtool is the inflate (that is noticable).

Hi bLawless, I have tried what you´re describing – just out of curiosity :slight_smile:
and for your info: I don´t have this problem – no matter which brush I´m using.
I have no idea why this is happening.
I really hope you´ll get it fixed.

Then this is a glitch of some kind. After seeing your post I have asked the artists around me about this and they know my problem well. It deforms, it is as if the brush hits a wall and skews.

But - I have replicated your NON problem too. So something is happening. Anyway, I have always had this problem, zbrush 3.1 windows, zbrush 3.12 mac, different machines (I have worked on four different machines, various versions of zbrush, and I zbrush eight hours a day for over two years now) and it happens so often that I thought it was the constant.

In fact, I ran over to a coworkers machine, windows, and she scooted out of her chair and I replicated your NON problem - but she was shocked, because she always has my problem as well. She quickly made two polyspheres, (new loaded ztools) and had the problem I always have.

So, I guess I will try to keep an eye on it to figure out what is causing it to happen.

thanks

Hmmm… that´s definitely interesting.
I just did it, and I´m a newbie - so there seems to be nothing special about it – easy-peasy.
But of course, if this would happen to me it would make me crazy, too.
As I mentioned before – no problem at all , no matter which brush I´m using ( I´ve used the Standard-, Layer-, Clay-,Elastic- and even the Stich-Brush).
And BTW, I have absolutely no problem if the tools have NOT the same resolution.
I don´t think it´s a Zbrush bug – if so, this strange things would happen to me, too.
But the fact you said this happens to others is really odd.
