Fantasy Trip Illusions

Then why can't they open (and close) doors? Where does one draw the line? (And part of my argument is that the RAW statement about "plants cannot be affected by illusions" -- because plants have IQ 0 or 1 -- implies "illusions cannot push plants aside".)

In most combat situations, it's unlikely someone would have the chance to notice things like that. More generally, I'd argue that "things giving away the illusion" is simply part of the limitations of illusions. They're not capable of being perfectly believable under all circumstances.

You could, I suppose, argue that that kind of "visual chrome" would be akin to the illusory cuts and holes in armor and clothing produced by an illusion's attack (though one could argue the latter is produced partly by the mind of the victim, so puddles and dust can't produce ancillary illusions).
