Questions & Troubleshooting for ZBrush 4R8

Im with both of you on that (it works and then doesn’t), but mostly I’m also haveing a hell of a time figuring out where to click.
So far it seems like the bottom of the thing is the only place it switches, anywhere else does things like turn on that (mostly invisible) stuff for setting where booleans start. I think that has something to do with it, rather than switching tools its trying to change boolean setting maybe.
Basicly you cant just click it any more, you have to click an inactive part of it, in my case the bottom.
I think

@MealeaYing

I’m guessing your problem with clicking on subtools could come from setting the UI to minimum size.
I work on a 1600x900 laptop screen so I have my UI buttons scaled down to the minimum (38).
Pixologic do state that neither this resolution nor buttons that small are recommended and that some parts of the UI may not behave correctly.

See if I make the buttons larger (say 42) the Boolean Group Start arrow is much better visible and separated from the subtool preview.
At 38 though the whole arrow / flag is barely visible behind the thumbnail especially if it’s greyed out.

I’m not about to make the UI buttons any larger due to lack of screen real estate, so I’m just getting used to clicking at the bottom of the preview icon.
(it’s a very small price to pay for the awesomeness of 4R8 features imho)

cheers

Thanks guys.

@MealeaYing: So far it seems like the bottom of the thing is the only place it switches.

Actually that’s what’s happening, I just tried it again. So long as I click in the lower half, it works. I’ll just need to be careful in future.

@Liseng:
Well crap!
Sorry about that, have you talked to Support?

@RafalZ
Yep!
That sounds right to me. Dammit.
I’m not planning on getting a new laptop till Pixo supports Linux which means I’m likely screwed.
And yah, its a pretty small problem considering all the cool stuff!

@Dillster:
Me too, Im already getting used to it.

Actually this question helped me figure out that was exactly what was happening.
HA!
I love how things like that work out.

Setting “Fade In Duration” in “Preferences > Interface > Misc” to 0 will cause ZBrush to start invisible. It’s on the desktop but not visible.

Qustion about Transpose,
Transpose lagging when I move object when Gizmo working just fine w/o any lags or delays
there is some solution how to fix it?

I just updated to 4r8 and close holes function will not work. Does anyone else have similar issues? Looks like I will be reverting back to 4r7 unless this is addressed.

@Jsterenberg

Close Holes works for me in R8. Do you have a screenshot handy of a situation where the Close Hole function does not perform the same as in R7?

Hi folks. I’m trying to decimate a head with 10 million polys…but it is taking so long to precompute the mesh, about 30 minutes.
Do you guys have this issue?

Hi,

I can sculpt in 4R8 for around 15 or 20 minutes, but then the sculpting brushes will suddenly stop working. I can still use the move bush, masking, Zmodeler. But I can’t use standard brushes, clay buildup, chisel, trim, polish etc. Nothing happens unless I shut down ZBrush and restart it. If I try to initialize it without shutting it down the problem does not go away.

Any solution?

Thanks

It seems like having spotlight images open on the screen might cause “unrecoverable errors” when I start using sculpting brushes. Is that a thing? I’m also wondering if there are compatibility issues with some of the custom brushes I have downloaded over the years, such as the SK brushes?

Thanks

Hi Guys,

What has happened to the fucntion where you start at brush stroke and hold down the SHIFT key to constrain the stroke to the screen axis??? I am using that all the time, well atleast in R7, so where is it now and how do I get it back ? … Now when I hold down the shift key, a really annoying and very hard to control Lazy mouse kinda line appear. And it also used to work when masking, that functionality is also gone!!

Please help, this new behaviour is so frustrating!

@Carsten

The new straight line functionality is as follows:

  1. Make contact with a surface (pen-down for a starting point)

  2. Hold down shift, and drag out the guide line to an end point. Note the number indicates the angle degree, so a “zero” would be a right angle.

  3. Release Shift while still holding the pen down, and the line will be drawn.

If you need a more interactive/pressure variable stroke, you will have to make use of the Backtrack feature in Lazy Mouse

  1. Switch on Lazy Mouse, Backtrack, Line setting.

  2. Turn the “track curvature” to 100, in order to get the stroke to adhere to the surface of the mesh.

  3. stroke back and forth between the two endpoints that setting produces.

Edit: seems Scott got here first :smiley:
@Carsten Lind

Hi, the functionality you’re describing has been integrated into Lazy Mouse 2.0.

I agree it’s not 100% the same but I would argue it’s better :slight_smile:
You can still create strokes that go vertically, horizontally and at 45 degree angle… but you can also make straight lines at any angle, plus you can actually see where they’ll end up before committing to them.
The thing to keep in mind is that you click, then click and hold shift to see the exact path and length of your stroke. When you decide the angle and length are correct you let go of shift and you get your straight stroke. You can also chain these strokes by keeping the pen pressed and just holding and letting go of shift.

The detailed description is in the Lazy Mouse 2.0 section of the documentation under Click-to-Click Straight Lines section.

One thing that’s not mentioned here is that if you set Lazy Radius to 2 or more then you’ll get snapping to 90 and 45 degree angles.
This will be represented by an extra green/yellow line.

Admittedly I haven’t used the 4R7 function too much - is there any other nuance of the old feature that’s missing here?
I’m sure the new control scheme with the visible line just takes getting used to.

cheers

@rodrigobraga

Hi,
On my end I haven’t noticed any difference between 4R7 and 4R8 decimation pre-processing time.
I did a quick test and per-computed a 27million point mesh and it took around 5 minutes.

This could possibly depend on mesh complexity and maybe other factors.

My specs are:
intel i7 3610 QM @2,3 Ghz (3,3 Ghz on turbo)
12GB RAM 1333Mhz
500GB hdd @7200 RPM

Is the time you measured consistent on different meshes/files?

cheers

@hellerd

Brushes stop working after 15-20 minutes work

Hi,
Nothing like this happens for me on 4R8.
I can say though that I did encounter a similar issue in 4R7. Specifically one brush (clay or clay buildup I don’t remember) would sometimes stop making strokes, but it was very seldom. I must have bumped into this issue just a couple of times since the release of 4R7.
That said I can’t be sure that this won’t reappear in 4R8, but it’s very sporadic and for the moment impossible for me to reproduce.

If this happens consistently for you, then you should probably submit a support ticket.

Is there an issue with Spotlight and ZB4R8?

I can definitely say that (at least on my end) no such problems occur with Spotlight and I use Spotlight around 90% of the time I’m sculpting.
I also use SK brushes and they work fine.

I shouldn’t go speculating on the nature of the issues you’re experiencing but maybe contacting Support is the way to go. Unless someone else in here knows what’s happening to your ZBrush.

cheers

Arrrgh - It feels so un-intuitive, un-interactive, clunky… I see that it is easier to get angled lines, but even the 0 degrees is not 100% horizontal, but only almost 100%. I would prefer to have a way to get the old way back, a setting in stroke or something. As it has been designed now, is just more painfull menu hunting which doesn’t help with the reputation that Zbrush has of a flawless UI (sarcasm may occur)

@Carsten Lind

As I mentioned: if you set Lazy Radius to 2 or more you get a snap with a visual indicator in form of a green line that turns yellow when you snap to it. It’ll get you perfect horizontal, vertical and 45 degrees strokes.

I’m sure getting used to it can be painful if you already developed muscle memory for the previous version.

As for menu hunting and ZBrush UI in general (sarcasm noted) I have the same response (and we can agree to disagree - it’s a philosophical dispute :smiley: ): ZBrush’s UI allows you to put (almost) any button or slider wherever you need it which makes it the most versatile and user friendly UI that I know of.
If you don’t want to add an extra button/slider directly on your UI shelves then you can always make your own Menu that will pop up directly under your cursor if you bind a keyboard shortcut to it.

I will grant you that with the current system you do need to have lazy mouse ON in order to use the Click-to-Click Straight functionality.
What could be cool is if Shift (pressed after you start drawing) automatically and temporarily turned lazy mouse On. (because now pressing shift after you start drawing does nothing if lazy mouse is Off.
That would be a nice new feature :slight_smile: I’ll even submit it as a feature request :wink:

Maybe there’s a way to do it already with a script or plugin or with an option I’m not aware of? I don’t think so, but would be cool.

cheers

@Carsten Lind

I know it can sometimes seem like any improvement in Zbrush is 3 steps forward and one step back, but I think if you actually make a pros and cons list of the change, you’ll find you’re coming out much farther ahead on balance.

RafalZ already explained how to get the increments to snap to the angles you want, although I personally dont have any trouble moving the line until any evidence of stair stepping is gone to get a right angle.

It’s amazing what we can get used to, because the old way of only being able to make a straight line at right angles and having to arbitrarily rotate the screen plane to get just the angle you want was insane. That screen rotation shortcut was so fidgety I only managed to pull it off about 70% of the time.

The new method is much closer to what you’d do in a standard app like photoshop by shift clicking with the paintbrush in between points, although with the added bonus of precise angle measurement for mathematically matched lines. It also enables continuous multi part strokes allowing you to easily make a series of straight lines that would have been a practical nightmare with the old method:

multipartline.jpg

It’s even pressure sensitive, so a light touch with the pen while drawing out the line will make a slighter mark, and heavier pressure vice versa.

The most valid complaint I’ve read from someone is that they prefer a more interactive stroke process allowing you to make corrections in pressure as you draw the line. While most of the time when drawing straight lines, you do want a consistent quality to the stroke, in the event that you dont, the Backtrack option is available for a real time straight line drawing. The Backtrack function is a discrete button, and so can be relocated on the UI or hotkeyed.


All that said, I don’t see any issue (other than potential technical issues I dont understand) with making the old behavior available when Lazy mouse is switched off. I personally dont use lazy mouse that often, because I don’t like the performance hit, and prefer a more organic stroke. It would be nice to have that option available without having to switch Lazy Mouse on.

It looks like my crashes were only happening when Spotlight was on. This morning I checked the box “Spotlight project off” in startup master, and so far no crashes.
