Eh? The book is achieved on completing a quest that involves bringing a certain number of a certain ore, not one that involves bringing a certain number of stock of a certain metal 

@Pizik: Really like the lighting you did on the last one, the golden sunlight is a great touch  Your UV mapping looks pretty good, except for the bottle where it looks a little blurry -- was the source blurry or a low resolution image?

How long did the last image take? It doesn't sound quite right that your first image took 11 hours to render -- they're simple shapes with no texture and only one light source that I can detect. A raytracer would get that done in a few seconds, unless you had quite an old (Pentium Pro- or Pentium II-class) CPU.

Interbreeding can be chalked up to fantasy-genre magic/tradition, but ear infections seems a little random. Parallo's suggestion of an injury sounds more plausible, especially since we already have precedent with the Klyros' wing spasms.

Nolthrir who spend too much time swimming rapidly may develop an infection of the ear and suffer from impaired hearing. Affected Nolthrir are asked to spend time on land until the infection subsides.

It's odd that Nolthrir would be susceptible to ear infections from being in the water -- if they evolved gills and such to live in the lake it stands to reason that they would have evolved a resistance to the infection as well.

Don't think it's been mentioned yet based on a search:

Without posting any spoilers, about the quest given by the NPC that can't see:
Asking the correct NPC for the first item is a little fiddly: "i need <item>" does not give a useful response, while "about <item>" does, where I think they should both produce a useful response.

The npcclient is down, which means that attacking anything is impossible, for the moment. It'll be back up when the devs have fixed whatever needs fixing.

I googled for some photos http://forums.se-nse.net/index.php?act=Print&client=printer&f=62&t=18193 and it would appear that infrared would best be represented by a red-white color. However you would have to fit models with an infrared color map and considering there is probably no tools for that(more than 3 colors and alpha channel) one would rather go with a parameter for each model that tells how "hot" it is.

There are a couple of ways I can see infravision being represented visually, aside from the standard blue/red/white (which realistically is monochromatic, ie black/white). The first is the way Kodak handled its infrared slide film (discontinued now I think): infrared is mapped to red, red is mapped to green, green is mapped to blue, and blue is dropped altogether; this produces a false-color image. Essentially the sensitivity spectrum is shifted to the left. The second way I can think of (that doesn't involve false colors or more than 3 color channels) is to convert the RGB (red, green, blue) triplet to HSB (hue, saturation, brightness), and use the infrared component to determine brightness. So the colors remain true, and their brightness is determined by infrared reflectance/radiation.

Of course, if we can switch between infravision and normal vision then the complicated schemes outlined above can be discarded, and just use the "traditional" red/white schema.

EDIT: It seems to me that, however it gets implemented, having an actual distinction between infravision and night-vision would require support for the following in textures:

An ir-reflectance channel. Measure of how much infrared radiation is reflected by the surface. Similar to current red, green, blue channels, only visible with a light source already in place. Means that light sources would also need to be configured to "generate" ir light, not just visible.

ir-radiation. Measure of how much infrared energy is actually radiated by the object. This would allow infravision-equipped characters to see even in total darkness (something night-vision-equipped races shouldn't be able to do), if there's something that's hotter/colder than the environment. Mostly useful for seeing living or recently living objects, it would be difficult to actually make your way with this, since in most places the ground, walls, and air have pretty similar temperatures. It would be like walking through a heavy fog.

Optionally, you could also have ir-transmit, for objects that are transparent to infrared. Gives you the ability to see through some walls, essentially, but only if coded as such by the devs.

This is, of course, all the speculation of one non-programmer. I'm quite aware that implementing the above would be quite difficult, since it involves code for which I'm pretty sure libraries aren't readily available, at least under a unified system that considers (human-) visible as well as non-visible radiation. And this is for a physically realistic rendition of infravision, and realism isn't always a priority, often taking a backseat to enjoyment and coding constraints.

From Webster:

Stereotypes aren't only created by a racist attitude. Even racial stereotypes aren't necessarily racist. A stereotype will exist anywhere that a subset of a particular group is taken to represent the entire group. For example, that doctors have bad handwriting. This is probably true for more doctors than not (I certainly have trouble reading my doc's prescriptions) but we can't know it's true for all doctors without obtaining a sample from all of them. Yet the stereotype exists.

Because most Diaboli are vain and unreliable, it becomes a Diaboli stereotype. Despite the "melting pot" effect, cultural behavior and attributes will be maintained because cultural groups tend to congregate due to reasons of familiarity. Chinese don't live in a Chinatown because they are unwelcome anywhere else, but because it is familiar, they don't have to deal with too much culture shock. For at least as long as such groupings exist (Gugrontid, Ojaveda?), such attributes will propagate themselves. Even where they don't, parental rearing has a great effect.

This is all assuming that behavior is learned and not genetic (or racial). If it's the latter, then everything above is quite moot.
