A further question on Invisibilty

[torelin32]

Hi guys,

Was reading the previous post on Invisibilty and I was wondering if you are invisible to Sight Group, would that mean thermal imaging as well.

I.E.: you have a ghost who for all purposes is invisible to sight group, but can be picked up by a thermal camera as a cold spot.

I would like to know what you guys think?

Thanks in advance.

It depends on how the thermal sensing device is built. If its "Detect Heat" power is defined as being part of the Sight simulated sense group, then Invisibility to Sight Group would make you invisible to the device. But if the power is defined as part of, say, the Radio simulated sense group (perhaps it's reading and interpreting electromagnetic fluctuations indicative of heat/cold, rather than actually "seeing" per se), then Invisibility to Sight Group would not make you invisible to it.

Sight Group includes any sense that is defined as being part of Sight.
Seeing IR, Seeing UV, Seeing Auras, etc...

As Derek says, if the IR (or other sense) is defined as part of another group then it will detect the character.

You know, it just occurred to me that IR touch is basically an Everyman sense.

What they said. If you want to build your ghosts so they show up to IR vision, go ala carte with your Sight Invisibility instead of buying it for the Full Sight Group. Or take a small-to-insignificant limitation to reflect the flaw in the invisibility.

Yes, if you are invisible to the sight group (not just the senses) then you are invisible to thermal imaging.

Thermal imaging works on IR radiation and IR is a radiation that falls in the sight group.

It occurred to me that a vague thermal presence could be reflected as the special effect for a Fringe as well.

The trouble with fringe is that it is distance limited. I can understand that from a game balance perspective, but it doesn't make much sense otherwise, for instance a faint thermal wash would be detectable by sufficiently sensitive equipment at pretty much any range.

Anyway, 'fringe' has to be detectable by the whole spectrum of senses you are invisible to, so you'd have to be able to detect it with normal sight. Arguably you could detect a heat shimmer with normal sight, but not in all conditions

It might be more appropriate concept to state that sufficiently sensitive equipment is built with Telescopic removing the Range Issue.

Things have to modeled both directions.

The second half of your post is a more accurate either way.
