Reflection using Environment Mappong

I wrote a program that doing a Reflection using Environment Mappong. I rendered the six cube maps. after I put the maps on a sphere, and put some other spheres around it, I noticed that when I moving around the sphere, the reflection is sometimes incorrect.
I understand, that if I move around the sphere I must re-render the maps, after rotating the point of view. otherwise I will see incorrect reflections.
Am I right?
