3DS Max - My models export with wrong pivot?

Hi all.

I'm here to give to you guys my problem... every model i build in 3Ds Max, in unity, the forward position is the bottom of my object. I realy dont know what i'm doing wrong. The front i build the front, the left is the left and the top is top... but after export FBX object, my model simply dont come right. the forward position is the bottom of my object.

Is there a bug or i'm doing somethink wrong!?

Best regards,
unknows.

 

in "Axis conversion" in the fbx exporter, have you changed the Up Axis to "Y-Up"?

 

for default the FBX Exporter set the Up Axis to Y-Up.
i'm thought about rebuild my model using the wrong orientation. Then probably my model export right. I'll build a test one.

 

Before doing that, if you haven't already, be sure to reset the pivot and re-export.


Go to the Hierarchy panel (to the right of the Modify panel), click Affect Pivot Only, then click Align To World, then click Affect Pivot Only again to turn that mode off.

 

helps if you have it centered in the the world also.

 

Well, i try to do that. but it continues wrong. i think i'll rotate the pivot to fix it instead of build a new model.

I dont understand what you mean.

 

Sorry, always worked for me. Usually it is the bip001 that is messed up, not the model. I have a utility script I run that fixes these issues for me on the scene. Perhaps it would work for you? It resets all the pivots and inverts any inverted normals. Of course, if you decide to try it, please save first!

Code (csharp):

1.  
2. fn isNormalFliped pt1 pt2 =
3.    (
4.       for i = 1 to pt1.count do
5.       if (length (pt1[i] - pt2[i])) > 0.0001 then return true
6.       return false
7.    )
8.  
9. fn doResetXForm obj =
10. (
11.    if obj == undefined or ((classOf obj != Editable_Mesh) and (classOf obj != Editable_Poly)) then return ok
12.     if obj == undefined then return ok
13.     if obj.mesh == undefined then return ok
14.     if obj.name == undefined then return ok
15.        
16.     s = "updating "+obj.name
17.    
18.    local oldNormal = #()
19.    for i=1 to obj.numFaces do
20.       oldNormal[i] = getFaceNormal obj i
21.  
22.    ResetPivot obj
23.     if classof obj.baseObject != Editable_mesh then return ok
24.  
25.    local newNormal = #()
26.    for i=1 to obj.numFaces do
27.       newNormal[i] = getFaceNormal obj i
28.    if(isNormalFliped oldNormal newNormal) then
29.       meshOp.flipNormals obj #{1..obj.numFaces}
30.    update obj
31. )
32.  
33. for ent in geometry do
34.    doResetXForm ent
35.  
36.  

 

Nice script. Thanks for helping me. It has been added to my utilities script package.
Well... I'll make a test with your script, but rotating the pivot solve my problem.

Thanks again.

 

I had this problem last week. Solved it here....

edit: I was using Maya. But I assume the solution is going to be similar or the same.

 

Try dropping a resetxform modifier on it, should fix it.

 

S O L V E - use own Unity pivot system "Hinge Joint", it is not based on exported pivots of Max or etc
