I'm away from my books but I'm still going over last night' session in my head. I pitted my players against a Bone Shambler and the group illusionist stopped it in its tracks by using the Stop Right There (complete with Meat Loaf moves and extra lyrics).
It got me wondering. Are undead even affected by illusions or do they automatically disbelieve?

I believe they are affected unless they are actually mindless. After all, plenty of cadavermen in the fiction have retained shreds of their former personality.

Stop right there - its not illusion

Long ago I asked the same question at forum.
Illusions affect undead. If something got any way to perceive world, it will be affected by illusions.

What about spells like Constrict Heart or Foul Vapours?

Our team fought stone Falsemen and I wondered about it.

4 ed - I hope that this small cutting would not break license.

- Foul Vapours "Those affected by the fumes do not have to breathe them, only contact is necessary—the spell affects both living and undead creatures"
- Constrict Heart "Some creatures are not affected by this spell, because they are undead and feel no pain or have no heart or similar organ to constrict."

Your interpretation is everything.

Foul Vapors works on any creature withouth forcefield stopping the fumes.

Constrict Heart doesnt work on majority of undead, falsemen, animated plate mails, unless it got working "pump/heart".
