Strange light artefacts rendering mesh
I have been working on a project for a while, helping my father.
What we want to do is add 3d shadows to a 2d flash movie, my father makes the flash movie, and I the shadows.The shadows are to be applied as a mask to the flash movie if all goes well.
It was all going smoothly untill i hit the render button, strange light artefacts appeared where there should be no light, and a mesh is rendering very poorly. I made the model i Rhino and exported it as a .OBj to maya for rendering, and i have been using the mentalray renderer. Here are some images that possibly makes my problem clearer.

https://imgur.com/a/9mssk : rendered image with light artefacts within red lines
https://imgur.com/a/zdYdD : screenshot from outside my model, with lightsource selected, and camera visible
Can anyone understand what is going on? Quick renders in Rhino showed none of theese problems.
Thank You!

check the normals on the mesh are facing the correct way round, thats what this looks like to me.
