Nope.

It's because .... let's put it in more matrix-y terms for a moment: The sensors in the drone that tell it how much weight it's trying to lift, and so on ... all those pressure/tactile sensors? Those are a Device (sub)node. They send a signal to the core processor. And, the spell SPOOFS that signal to be one that indicates weight, pressure, whatever.

Now, do you see? The drone think there's pressure or force being applied ... when there isn't. But, all the drone (or a person fo that matter) knows of the universe, even their own body, is what information their senses send to theri brain.

The spell takes control of that information. Nothing more, nothing less.

Awesome things.

Then if an illusion can automagically spoof any sensor with no checks required, what's the point of having a hacker?

For one, you have to know the sensor is there.

For two, the Hacker can spoof the sensor for an unlimited number of people at once; the spell however has to be used and re-used for each, in turn.

For three, the hacker can do a lot more than just spoof sensors.

For four, who said there's no checks, at all? If an illusion can be resisted, then, that's a check right there.

Ummmmm... Drones do not get to resist Illusion Spells at all. If the spell beats OR, the Drone registers whatever the spell tells it to.

"Beating the drone's OR" ... that involves rolling dice, right? Well, then ... that's a check!

Certainly not the mage just saying "because Is aid so".

You've never met my group's mage, obviously

So if you make an illusion of a gun, and shoot someone with its illusion bullets, do they still take real damage?

Just use the "Agony" Spell for that.

Don't forget that it's entirely reasonable for a GM to roll the dice on spells like this, where the player can't very well verify the result until it's being tested.

Physical mask is a multi-sense illusion as such it fools touch, but it's still an illusion which means it conceals what's really there it doesn't change it. As such your fingerprint would still be your own, but you might be able to fool a retinal scan if you knew exactly how someones Iris looks, that would require knowledge, close study and very good memory (as you can't plug an input into your spells)
That said, trying to explain magic with logic, physics or any other measurable metric falls to pieces pretty quickly. It's magic, it defies explanation and rationale despite what fluffy explanation you put on it... Because it's bloody magic.

The question is the exhaustiveness of this physical illusion. Do you simply look, smell, feel, sound, and taste like the person or do you appear to be the person? I should probably explain the second line. There are multiple aspects of a person that can identify a person beyond the five simple senses. Posture and gait are two examples of the body language that uniquely identifies a person. Does that mage with a limp in his left leg that slouches all the time appear to being that high level executive with a limp and slouch or does he appear to have a normal gait and walks with thorough assertiveness?

As a GM, I would rule that the assertiveness and lack of a limp, would be call for some Con (Acting) rolls.

The spell is the costume, but whoever's wearing that costume still has to put on a performance.

Kind of hard to put on a Performance when you do not even know what the Performance should be. Which brings us back to Biometrics. If you have to make a Performance (as you so eloquently state) for things you may be unaware of, how the hell is the spell covering Biometrics. The short answer is that it doesn't (and shouldn't).

Oh, I agree. If you can GET the biometric data, though, the spell should be capable of handling that. A good set of mundane disguise equipment could, after all.

Yeah, you have to get the biometric data in a format your mind can process (nearly impossible, esp. a DNA sensor), because magic can't access a database.

Have fun processing 3,27 × 10^9 base pairs.

Look at all the Geneware that relates to DNA. Even the scanner itself doesn't try to process the ENTIRE strand of DNA. It looks for a few key markers; the higher the scanner rating, probably the more bits of data it looks at. But if you can learn what the scanner looks at, you can just mimic THOSE particular bits of data. *shrug*

And that would clearly, IMO, be a case of an opposed test, comparing the mage's initial successes with the spell against the scanner's roll.

That .... thatw ould be a flaw in the rules, IMO. And would thus be cause for a houserule.
