I have an issue where any lights I add to my scene, the light does not fall properly on the static scene. The light works properly with any meshes I programatically add to the scene, but not the scene itself.
Here is what I posted in the help thread.
I have been experimenting all morning and found some additional information. I think something in my blender scene itself got currupted. I can reproduce the problem if I create a new basic scene, and add rotations in the dotscene export screen. But I still have the problem in my scene even without the rotations.
First, I created a new scene that was nothing more then three planes, each perpendicular to the other so it like one corner of a cube. The visible faces point inward.
I did a regular export (dotscene with no rotations) and the light worked fine when placed in the center of the three planes. The light source is the white dot in the center of the three planes. You can see the light falls on each plane equally.

I did another exporting with a 90 degree rotations(RotZ = -90) and got this. As you can see in this one, the light isonly lighting up half of two of the planes.

This is the problem I am having with my scene. Unfortunately I have this problem without any rotations. It took quite a long time to create it, and I the thought of starting from the beggining scares the hell out of me. But apparently something in my scene got currupted. If anyone has any ideas it will be greatly appreciated.
PS. It apears to me that when you export from blender, what is up and down in Blender does not end up being what is up and down in ogre. For instance, in Blender, if I hit numpad7, I will be looking down from the top at the floor of my scene. But if I hit ctrl1, then I am looking down at what is my floor from ogre. Is something perhaps wrong in my setup?
