Which version of Vue are you using? I understand now what you're saying, and I have just been trying this (with Vue 4 with the 4.02b patch), and I have tried it with both procedurals and textures, in Object Standard and Object Sphere mapping, and when I rotate the sphere, the spotlight stays in place and the sphere stays lighted in the same way. When yopu rotate your sphere, is your spotlight rotating along with it? is the spotlight linked to the sphere under the animation controls above the world browser? There has to be a simple explanation to this problem. Have you tried your other lights to see if they are doing this?
