Showcase of how the mod Tapetum Lucidum: A modular catsight, version 1. 2. works.
With the Quen light-casting mod (latest version of Eternal Hunt, or E3 Quen (NEXT GEN)
What to expect:
Modular, light-reflecting eyes that depend purely on environmental conditions.
They are capable of burning like candles, yet they do not emit any light themselves.
The behaviour is very variable from subtle, moderate to strong, depending on the surrounding light and Geralts' head movements.
An attempt to show how the eyes of a monster slayer could behave, with new, detailed textures.
Main version with thin, rounded and extra-wide pupils, plus alternative versions for regular eyes or swapped alt-regular modular eyes.
A picture speaks a thousand words — check out the videos showing how they behave in changing light and environments!
Goals:
1. Firstly, the light-reflecting behaviour of the eyes, which is common to many mammals and is caused by the tapetum lucidum (or 'bright tapestry'), was the focus of attention. This tissue multiplies the strength of incoming light, resulting in better night vision and a haunting, illuminated gaze.
2. It was crucial to make the pupils glow in the right dim conditions, but not the irises.
3. Conversely, the pupils should be as dark as possible in direct light, with the irises appearing shiny.
In short, the pupil and iris exchange roles in terms of brightness and light absorption during the day and night.
Of course it's a trick. Its all down to the normal maps. No glowing effects were used. I spent more than half a year learning, balancing and going back and forth to achieve this result (well, of course, it was mainly because I didn't have enough time, as everyone here). The key was to make the normal map behave as an impenetrable barrier when needed. The pupil reflection is forced to react to side light, only a bit to upper light, and not at all to direct light. I believe it's a close-to-right result for now.
