GOZ Flipped Z axis C4D

ZBrush Usage Questions
#1

Cinema 4D S22 now supports GOZ again. YAAAY!

One thing I noticed though is that the Z axis is flipped upon import. I believe this has always been the case.

So if you begin a sculpt in ZBrush then kick it over to C4D it’ll be facing backwards in Cinema. When exporting/importing an obj/fbx into C4D you have the option to flip the Z axis to avoid this issue. That has been my work flow but it would be nice to just use GOZ.

Anyone have a solution other than manually rotating every time?

Hi @Tristan

Did you try turning off “eFlipZ” in “Preferences > ImportExport > Export”

Thanks @zber2

I just gave that a shot and unfortunately it didn’t work.

@Tristan

I think @marcus_civis would probably be the most qualified to assist you with this.

Hi,

Yes, GoZ has its own setting, depending on the application. For Cinema 4D you will need to edit the C:\Users\Public\Pixologic\GoZApps\Cinema4D\GoZ_info.txt file so that
this section:

EXPORT_FLIP_X = TRUE
EXPORT_FLIP_Y = TRUE
IMPORT_FLIP_X = TRUE
IMPORT_FLIP_Y = TRUE

is changed to something like this:

EXPORT_FLIP_X = TRUE
EXPORT_FLIP_Y = TRUE
EXPORT_FLIP_Z = FALSE
IMPORT_FLIP_X = TRUE
IMPORT_FLIP_Y = TRUE
IMPORT_FLIP_Z = FALSE

But you will need to experiment as I don’t have Cinema4D! For example, you might need to set FLIP_Z to TRUE.

The ZBrush import setting should be the same as export so that the model is correctly oriented when importing back in. You might find this ZTL useful:
Axis_example.zip (11.1 KB)
It has the different axes clearly labelled so there’s no mistake as to which way it is facing or if it is mirrored.

EDIT: Tristan solved this using my suggestion - see below.

Attn. @Tristan ^

Thank you @marcus_civis

#7 
EXPORT_FLIP_X = FALSE 
EXPORT_FLIP_Y = FALSE
EXPORT_FLIP_Z = TRUE

IMPORT_FLIP_X = FALSE 
IMPORT_FLIP_Y = FALSE
IMPORT_FLIP_Z = TRUE

@marcus_civis That did it! The axis example really helped. Thank you and thanks @zber2

WOW so glad i asked. That’s one of those things i would have just lived with but I’m starting to learn it’s worth just asking around here hahaha.

Having the same problem in with ZBrush 2021.7 & 2022, C4D s24. :disappointed_relieved: Never happened before but I haven’t GoZ’d in a while. This is what worked for me with those versions:

EXPORT_FLIP_X = TRUE
EXPORT_FLIP_Y = TRUE
EXPORT_FLIP_Z = FALSE

IMPORT_FLIP_X = TRUE
IMPORT_FLIP_Y = TRUE
IMPORT_FLIP_Z = FALSE

And here’s a little smiling ZTL to test directionality with:

I am having the same problem with ZBrush 2022.0.5 and C4D R26.107. Unfortunately, changing the GOZ_info.txt does not make any difference for me. Are these settings stored in another place now?

Exporting and importing with OBJ files is working correctly.
