Freez camera vactor to paramter position ?!?y

Hello, i was working on sphere mask but when it come to change mask potion i find a problem that because of the changes of camera vector it change the position , am using this material ![alt text][1]

but when changing the camera potion it change to this

my question is how to stop the white ball from changing the position when camera change potion!?

Do not use camera vector.

If you want static Sphere Mask, use WorldPosition and XYZ vector, which is world coordinates of mask.

If you also want to move this object, use ActorPosition to correct mask position (add it to location).

but that will stop the 3d sphere effect i want to move the sphere (white sphere) to the left as you can see in the images and i want to stop camera vactor from changing it position when the camera change it position . using world position will remove the screen position or 3d effects that i want

So you want to move white sphere with camera, but don’t want camera to affect it?

It’s a little absurd )

Yes that what i want , if you please can show me the way to do.
