I don't see any reason that you shouldn't adopt that. Though a case could be made that the realistic effects of UV vision are no better than a perk; and perhaps that the realistic effects of NIR vision likewise are no better than a perk. So that would be something to think about if you're coming up with variant rules for even greater realism.

No NIR is equal to multiple levels of Night Vision In almost any situation where you have visual spectrum light you will have near-infrared too.

Gathering the NIR as well as the visible light gives you more photons to use. That's why technological "Night Vision" devices do this.

Does the same argument apply to realistic UV?

Yes, but to a much smaller extent.

That might be better as "chips designed with technology better than that of 2008 are too small." There are an awful lot of chips made with less-than-leading-edge technology, because older-generation manufacturing equipment is cheap, and good enough for many purposes.

To recognize a person, you have to see more than a blob. A successful vision roll is 'see and recognize', not 'see'.

This probably has to do with pupil size, and doesn't apply if you don't have Bad Sight. Also, your direct indoor illumination is likely 1,000 lux or lower.

Visibility modifiers in combat.

Typically adding NUV will give you something like 10-20% more light if it's sunlight, almost nothing if your primary light source is fire or incandescent. Adding NIR will give you around double the light for sunlight, something like five times the light for firelight.

I think you must have misunderstood me. I was talking about things like Dungeons & Dragons Darkvision, which has an abrupt cutoff at sixty feet, or the radar screens in many video games, or hypothetical FTL scanners, or other such devices.

Well, personally, I enjoyed the PDF.

But I was hoping to find a official version of the Dark Sight enhancement suggested by PK, in a thread that I oponed some time ago (http://forums.sjgames.com/showthread.php?t=129188):

Quote:

That works out to +8 points or +10 points, which seems fair considering the hefty degree of overlap.
Anyway, very nice PDF.

And about the discussion... there will be an errata or it's ok? Because you guys do sound like that the PDF need an official adjustment for some advantages.

Blood Taste
9 points
Included in: Enhanced Senses.
You can identify human blood types from a few drops on a successful Taste roll. You must actually take the blood in your mouth to do so. On an IQ roll, you can recognize an individual’s distinctive combination of blood components if you have tasted his blood before, or recognize toxins and other pathological conditions. For other species, apply the appropriate physiology modifier (p. B181).
Statistics: Detect Blood (Analyzing, +100%; Biological (Passive), ‑5%; Taste-Based, Reversed, ‑20%) [9].
This build doesn't seem quite right to me:
Quote:
Analysis Only: You cannot use your Detect to detect the substance! However, once you’ve located it using your other senses, you can analyze it normally. -50%.
Detect Blood (Analyzing, +100%; Analysis Only -50%; Biological (Passive), ‑5%) [8].

You can Analyze blood if you can do one of: see, smell, touch, taste, or somehow hear it. Which is better than "Blood Taste" because you don't really want to have to put random bits of blood in your mouth.

You may very well if you're a sanguinivore, or a creepy supervillain, or a vampire.
