feature request: fixed Y rotation

Hello,
When balancing our models we need a fixed Y rotation.
One that is fixed ‘completely’, so that we can rotate the entire statue to be certain it is well balanced, avoiding any ‘lean’. As it is we have to ‘eyeball’ any three quarter views. Clients want turn around screenshots and shift snapping works great for side views, top, bottom, and rear. But we need three quarter shots too.

Thank you,
Brandon

Having it in the viewport would be awesome!
you can currently ghetto rig it though.

transpose master>deformation>y rotation 45%>transpose master.
Now your snaps will work to the 3/4 views. It should get where you need to be for your client for the mean time at least.

Hi,
In short - good thinking, good instincts. But we thought of this and have tried this, but with experience it is not practical.

To elaborate:
I use transpose master when beginning a project and meshes have not gotten too complex and my subtools are under 15 in number. But we have on average 100 subtools. Transpose master crashes once in a while for various reasons. When you have over 15 subtools transpose master crashes more often than not. (Again, this can be for a number of reasons, one being a digital scan brought into the ztool from another program). Also you will sit and stare at your screen for an hour before transpose figures out 100 subtools, if it doesn’t crash.

I totally agreed with Brandon. This would a great help.

Count me in!! What’s the point of the current Y axis rotation? It doesn’t really stick to Y, you can still tumble. A locked Y would give us the ability to realtime turntable. Artists have been doing this for centuries.

Touche Sir.

I didn’t realize who I was telling that too. I’ve watched your work for sometime now, great stuff. But yes, completely worthless for what you’re having done. I’m really hoping you weren’t on the Beta for 4 because that would mean that folders and everything else you ask for (me too, just not vocally) will be missing from 4.

I love Z. Hands down would be a fan boy. The program actually got me working with characters again, and loving sculpture again. But without some of the main pipeline improvements I will be forced to switch to mudbox. Texture Layers, Subtool Folders, Export and Import improvements, Real time shaders would be nice…but not needed, etc.

I do not want to change from Z, they are what made this possible, and I hope they are not lagging behind in this race.

Anyway, yeah, with over 10 I don’t try to use Tpose either, it just crashes…and the lag/hang up kills me everytime.

On a side note, when I am over a certain number of subtools (10+) I break an object into multiple meshes/ztools. You can manage them a lot easier and then use subtool master to import them one at a time…but this is a long and tedious process and by that point you’re better off just using the “eyeball” version of it.

eh…hopefully pixologic has been listening for the last couple of years.

Well I won’t be switching to Mudbox myself, for many reasons - which I won’t list. Fixed y rotation will be nice, one day, when it is implemented.

Transpose Master has been updated for ZBrush 4, with many improvements and fixes.

For the fixed Y rotation, you might like to try this. Unzip to the ZStartup/ZPlugs. Restart ZBrush and there will be a new submenu called Y Axis Rotation in the Transform palette.

Set the Rot Incr slider to the increment you want, as part of a 360 degree turn. So for 45 degrees set the slider to 8. Then press the Rotate button and a model in Edit mode will be rotated by the increment.

There are a couple of issues - the canvas needs to be set at Actual Size. And sometimes the model will flip upside down, though setting the slider to a high value seems to fix this.

Thanks Macus that’s perfect.

Holy Smokes, Marcus, you’re a wizard!! It works perfectly. Thanks!!

Ask and you shall receive.

Thanks a ton Marcus.

Thanks guys. :slight_smile:

The flip issue is something called gimbal lock and can occur when the rotation nears exactly 90 degrees. To avoid it simply start from a position which is not snapped absolutely face on at 0 degrees. Only a tiny shift will fix it.

Hello,

If you answered this before, forgive my not seeing it. Was wondering how to correct when the turntable rotates the object end over end rather than around?

Thanks,
Cris

You can set the axis of rotation for a movie turntable in the Movie>Modifiers submenu. The default axis is Y - switch to X or Z as appropriate for your model.
