Problem of Export Scene in Maya with OgreMax

[jbcjay]

Hello, everyone.
I'm having a problem with exporting the scene in Maya with OgreMax.

In order to illustrate my problem, I created a simple cylinder in Maya and exported the scene with OgreMax.
But the exported mesh in Viewer is not what I want, which has been changed somehow.

Below is the cylinder in Maya:

Here is the exported mesh in Viewer:

The problem is my whole cylinder in Maya is red, while the exported mesh seems to be dim in the Viewer.
Could any one tell me how to solve this problem?
By the way, I'm using Maya 2012 and the version of OgreMax Scene Exporter for Maya is 2.4.3.
