I'm not sure you really mean aliasing, but maybe flickering?
If aliasing, you need to up the AA quality in Max, since AA is taken care of by Max and not Vue to ensure the same level of AA on all elements in the final render.
If you mean flickering, which I think it is, because it always happens in animations, you need to use separate render settings, to enable texture anti aliasing and texture filtering in the Vue render settings. Use 33% texture filtering, or use an animation render preset (starting from "Broadcast") Use texture AA only if you also see some flickering in Vue procedural materials (such as barks, terrain materials...) Texture AA will add render time, so use it only if necessary. Texture filtering doesn't add much render time and is mandatory for rendering animations.
