Problem with script (MouseScript js)

Hi all, i have a problem when try to apply a script js(with OnMouse function an draggin) on 3dmmax imported object. I try to move a objet with my mouse but nothing happens. If i apply my script with a primitive object like a cube, all works.

Please need help, how can i resolve this problem?

You probably haven’t added a collider to the object from 3DS. Also, in order to guarantee it’ll register your clicks, you’re probably best off with giving it a basic collider type like box or sphere, not mesh.
