Assuming you are using the 'View' AS the Reference Coordinate System in 3ds Max, Then in the front view port, Rotate the objects' Pivot along the X axis 90 degrees. Try using the latest Fbx plug-in, export the mesh with the Up-axis set to Y-up in the Exporter Dialog settings. "So just as long as you in Max have X 90,Y 0,Z 0 in rotation and export with Y as up in FBX, you should be fine." -holmeren Once the mesh is imported into Unity Select it & in the inspector Check "Generate Collider" the box.

I'm not sure what do you mean by first one, but the second one I just fix the orientation of a pivot in 3dsMax - you have to make usre Y axis is going up.

I found a piece of script to handle this on my batch export from Max. I use the "Batch It Max" script (find it on scriptspot.com) to run this on all of my MAX files to convert them to FBX and auto-rotate them. At one point, it was working...now it's not. The FBX file comes into Unity at 0 X rotation, but it is facing sideways. Any ideas on how to accomplish this pivot rotation in MaxScript? Thanks!

fn SetObjectRotation obj rx ry rz = ( -- Reset the object's transformation matrix so that -- it only includes position and scale information. -- Doing this clears out any previous object rotation. local translateMat = transMatrix obj.transform.pos local scaleMat = scaleMatrix obj.transform.scale obj.transform = scaleMat * translateMat

 -- Perform each axis rotation individually
 rotate obj (angleaxis rx [1,0,0])
 rotate obj (angleaxis ry [0,1,0])
 rotate obj (angleaxis rz [0,0,1])
