Import/Export settings. Change on default?

ZBrush Usage Questions
#1

Hey guys,
I tried to export parts of models into zbrush but it’s scale keeps messing up.
In the export setting, it comes out as (scale= 0.62134124), and the axis have been changed too.
So I bring the scale to 1. Change the axis to 0, 0, 0.
Re import the model I was working on, and it’s positioned differently.
I tried to bring other parts of the model in and it automatically imports it as .613412 scale and I have to change the export setting and bring it back.
Basically it imports it as a smaller scaled model in a different position then after I change the export settings to 1, 0,0,0, I import the model in and the scale is finally 0.

How do I freeze all the import models scale as 1?

When importing an OBJ into zbrush, it will be assigned a random scale. (something to do with the preview window in zbrush I think) So, what I do is:

Import my obj into zbrush.

Go to Export menu and set sale to 1, position to 0,0,0.

Re-import the same obj over the top of the first one you imported.

The obj should snap to the correct scale and position. Now all import and exports for this tool will be synced up with your application, as long as it is the top subtool in the list.

New subtools appended will inherit the top subtool scale.

This is how I do it in XSI anyway. Hope it helps.

i don’t understand why it would change scales randomly like that… is there a way to set it so it DOESN’T rescale everything?

Go here, I just wrote up why.

i wrote a small script that resets those settings as well as some of the export settings(you can delete what isnt applicable). i copy paste this a few times so it will do a number of subtools at once, if you dont like that remove the subtool part

//RECORDED ZSCRIPT 3.5
[ISubPalette,“Zplugin:StupidExtras”]
[IButton, “Zplugin:StupidExtras:ResetExport”,“Reset”,

//EXPORT
[IUnPress,Tool:Export:Tri]
[IPress,Tool:Export:Qud]
[IUnPress,Tool:Export:Grp]
[IPress,Tool:Export:Mrg]
[ISet,Tool:Export:Scale,1.000]
[ISet,Tool:Export:X Offsett,0.000]
[ISet,Tool:Export:Y Offsett,0.000]
[ISet,Tool:Export:Z Offsett,0.000]

[IPress,Tool:Subtool:Select Down]

thats a cool script, but it won’t solve your problem. Zbrush doesnt handle
your objects perfectly at scale 1, offset 0,0,0. every object you import has
different values. and when things go pearshaped (ie wrong size in maya or
max) then you have to put those values back to the original, which is never
1,0,0,0
