Materials-Textures

Diametric Reflectivity Extension
(material rendering approach)

SpecularXY - sharp edge (light)
SpecularZ - far inner (spheremap-filter)
ReflectionXY - narrow (cubemapped)
ReflectionZ - near inner (raytraced)

This is a stylistic paradigm to rendering materials in a fundamentally different way, by using two opposing textures and shaders for both specularity and reflection. In the rigid realm of modern physically-based rendering orthodoxy, there are two benefits to following this technique. These two opposites can be adjusted and exploited to create reflection offset and sweeping effects during movement and animation, to result in highly reactive hyper-reflective stylised visuals, still being compatible with current standard material practices, and is also geared toward being more optimised from an artistic discernment, in conjunction with (and not only) a technical one.

The inherent philosophy is that physically-based rendering should become a necessary refinement over time, not an initial enforcement to obey, and the reality is that our workflow is at great risk of this rigidity while the concepts within the projects themselves can only benefit from such unconventional approach, and this is fully suited to the characteristic of the team. It actually allows for great flexibility in how a surface can be stylised in terms of light interaction and reflectivity, not only in parametric and programmatic terms but also artistic ones, as only a texture adjustment may be required and thus under complete command of mappers and texture artists alike. These extra texture passes are easily derived and compounded from the standard ones compatible with modern physically-based rendering, and optionally broken apart or composed together depending on necessity, all entirely automated within our integrated development environment.

The meaning involves both diametric in a stylistic sense, but also a technical one in terms of optimisation. At any one time, only half of the surfaces within a scene should be using raytraced reflections, and then only half of those again would have a depth higher than one. This is true for rendering distance and some options within material scripts, but this approach allows it to be true for more developers to decide how and where it should be optimised, and even more heavily so, by virtue of a raytraced reflection always having a cubemap bake to deprecate to by default, and therefore able to be optimised in more subjectively aggressive ways, even foregoing entire texture passes completely. The belief is that aggressive optimisations with one hand allows freedom and privilege with the other, and isolated focused accurate reflections can be achieved where necessary while technically, being friendly to performance, and artistically, friendly to creativity.

It's also possible, at least within our offline rendering workflow, to subjugate the more demanding reflection standards for lesser ones, either in part or as a whole, or vise-versa if desired. Both the reflection axes can be assigned to either low-res spheremaps (used by specularity), medium-res baked cubemaps, high-res baked cubemaps, or per-pixel raytraced reflections, or any combination or order therein. This means that scenes can be as infinitely reflective as the mapper intends and will take as long to render as necessary, without being restricted to real-time performance limitations, while at the same time being fully scalable down to a rendering approach multiple times removed from the current generation of real-time graphics, all using the same content and all mostly automated.

The goal is the ability to render something that is "more reflective" than the most highly reflective thing perceptible under the suffocating constraints of modern realistic rendering, even if that itself becomes unrealistic in favour of stylisation and artistic endeavour. This especially matters while enduring a lot of movement and animation where reflectivity really matters although often becomes lost. The intended purpose of offsetting axes in both reflection and specularity, using this technique with different methods, aims only to enhance it.

• _clr = colour ("diffuse" texture to assign colour)

- high colour-saturation with highlights and shadows removed.

• _bmp = bump/height (parallax effect - dark=low, bright=high)

- X2 resolution and soft, without small harsh details.

• _nrm = normalmap (colours represent angles to distribute light)

- derived from the bumpmap but sharper and with harsh details.

• _spc = specular (determines where highlights from light occurs)

- focused on edges, high-contrast, sharp and noisy.

• _rfl = reflection (determines where environment will be reflected)

- focused on middle features, high-contrast, soft and smooth.

• _occ = occlusion (helps prevent the material from washing-out from strong lights)

- focused on edges and shadows, low-contrast, sharp and noisy.
----------------------
All of these "textures" are combined together in a "script" to create a "material".
The script determines environment reflections, "detail-mapping" and other attributes.
The textures (.TGA/.PNG) must be compiled into .DDS files to load in the engine faster.

- displacement types (to levels):-

.=small O=big #=soft !=sharp -=shallow ) displacements which slot into somewhere between the 2nd and 4th subdivision, and allowing extremely small/sharp/shallow (.!-) displacements that have effect from the 3rd up to the final 5th subdivision and the beyond final smoothing operations. At that point the resolution of the final normalmaps will not be able to translate any more detail. This method also ensures there are no arguments between the displacements as originally ordered, to avoid folding and countereffective values in any one area. Almost nothing is displaced at level 1 subdivision which is still considered as an interpretation of the original mesh and displacements that large and soft would be done by actually adjusting the original mesh.

(maps):-

- colour/diffuse/albedo +alpha (24/32bit)
(only colour values, no shadows or highlights)
"you will need to give this much less contrast but much brighter/colourful,
because PBR will never allow other values to oversaturated/flood this pass."

- normal/local (24bit)
- bump/height/displacement (8bit)
"didn't really change, straight-forward, except IOR/refraction is calculated
using a different pass, depending on the material configuration."

- ambient-occlusion/cavity/shadow/modulate (8bit)
(shadows (cavities) isolated from diffuse)
"basically taking whatever shadows/low-light information was in the diffuse
and isolating (perhaps assentuating/spreading-out) into its own pass."

- specular/spec (24bit)
(basic specularity)
"this is only used to simplify a material, otherwise (in combination with all
other maps, including normals and diffuse) is split up into the 2 following):-

(or):-

- metallic/metalness/reflection/ref (8bit) (maybe 1-4bit?)
(what is reflective (conductive) and what is not (insulator))
"basically the 'ref' pass we're already using, sometimes put in the
alpha of the diffuse map for old 'environment-mapping'."

- roughness/glossness/gloss/micronoise (8bit)
(defines the sharpness/clarity (or lack thereof) of color reflections)
"basically the 'sharpness' (in combination with the previous mention) of
both specular and reflections, calculated per-texel instead of material."

- refraction/IOR (8bit)
(how to bend light through alpha'd (semitransparent) materials)

- emission/add/additive (24bit)
(colour values that ignore lighting)

(other (very optional) maps):-
- translucency (maybe called 'fresnel map').
- tint (used to add colour to semi-transparent surfaces (stained-glass)).
- hitmap (what particle to emit per-texel, conceptual surface type).
- alpha (if the alpha channel is isolated to allow for unqiue scaling).

(parameters):-
- shading type (fresnel/blinn/phong/etc.)
- fresnel bias (grazing(/edge) reflection).
- cubemap interactions (resolution/updates/specify?).
