Hello,

We are using physx 3d max plugin (3ds Max DCC plug-in 2.8.9 (v03131509)) and export physx scene for 3.x engine as xml file.

The problem is, we couldn't find an option to change up axis (max is using z as up) and I strongly believe there is none

In order to fix the problem we rotate and translate relevant objects. But this trick doesn't seem to be a good solution more over I suspect it will work for constrains. (And it is problematic, we are doing a lot of tricky things to export the scene properly)

Probably there are people like us out there. How did you overcome the problem ? Thanks

You can change the up axis in 3ds max. It's in the prefs. To convert pre-existing assets, a 90 degree rotation around x applied in world space is the only solution.

I search through web for changing up axis of max. Many people say, there isn't such option

here is my solution which matches all axis with opengl


-- rotate selected object
obj = $
rotate $ (angleaxis -90 [1,0,0])
a = $.pos.z
$.pos.z = -$.pos.y;
$.pos.y = a;
