transform at export to Unity facing incorrectly

[Anonymous]

Hi, 

I set the z-axis facing to the front of a model but at export in Unity it shows facing in a different direction.

Regardless where I set the axis at Maya, the transform faces differently at Unity (blue also forwards at Unity).

Can you please help?

Thank you, Sergio

Maya View before exportUnity view after export

is your Up direction in maya is (Y) axis

There is a description in Unity help.

This is an example.

Hi Tony

Thank you for the link you've provided and apologies for my late response, with December festivities I didn't get a chance to log back in.

Unity also uses Y as up vector, so changing Z for up does not solve it. The problem I have as shown in the pictures I posted is that Z is looking backwards.

Any other ideas please? 

Thank you! Sergio

Hi!

Check scaling.

Avoid having scale on your Transform node. If you don't really need it, all Scale values of a Transform node should be [1 1 1].
Select all Components (like Vertices or Faces) and scale them for modeling or use Freeze Transformations ("Scale") after you scaled the object with a global scale.

For further help, please upload a scene-file.

Hi mspeer, thank you for your guidance. The transform was not scaled, scale is 1.1.1. In case also froze transform-scale as suggested.

Z-axis problem facing backwards when exported into Unity persists when exporting the model into Unity.

Attached maya scene with model. Here's git's Unity project/scene https://github.com/sergiosolorzano/Unity-MayaTransformDiscussion.git

Thank you for your help.

Cheers, Sergio

Hi!

I just opened your scene, also facing backwards.

1. Get rid of unnecessary stuff inside your scene (a lot of empty transform nodes).

2. Check your Tool Settings.

3. Try a reset of your preferences.
Rename the folder prefs in folder 2018 to something like prefs_backup, or to reset everything, the folder 2018 to 2018_backup (or even the maya folder to maya_backup). Maya creates new folders (don't copy preferences from previous Maya versions). Detailed at:

Hi mspeer,

Thank you for your message!

I have deleted the empty transforms and renamed prefs.

After renaming prefs Maya won't let me change the orientation of the axis - after I click away from the model the axis revert back to original. I am pressing D+rotating the axis. Here's a vid: https://youtu.be/Hr_e9RJrIXI

I tried this in a new separate scene with renamed prefs but the problem persists.

Before renaming prefs, Maya allowed me to change the orientation of the axis and the change persisted as long as the session was opened. However, when saving and closing and re-opening the scene, the axis faced backwards again. I also tried this in a new separate scene with old prefs but the problem persists.

What am I getting wrong?

Thank you for your help, Sergio

Hi!

You forgot Bake Pivot.

But why not just simply select all components (faces or vertices) and just rotate them by exact (with step snap) 180 degree.

Correct object orientation and correct orientation in scene (world orientation) with one action.

when I 1.rotate the pivot and 2.do bake pivot then, our rotate coordinates of the object do change for 90(so my post imported model looks the same), if I tried to reset transformation, the model is turning to zero rotate position, how can I change those axis directions without rotate that fkn model??
