Specialized surface families

Specialized templates combine texture samples with world position, vertex data, camera direction, lighting or time. Uniform-texture execution establishes channel arithmetic; spatially varying textures are needed to distinguish UV routing and parallax. Nine major specialized families have both kinds of execution checks, including independent Direct3D 11 WARP runs on 128×128 textures sampled over 16×16 output grids. Proven · covered nine families

Ice and layered rock

MAD_Hero_Ice mixes two surface colours through t80.R and two deep colours through t75.R. Frost t81.G warps both UV axes by (1-sat(t78.B))*FrostPower. The final colour interpolates between screen blend 1-(1-surface)*(1-deep) and multiply surface*deep; its weight depends on shaded normal, light and view. Roughness is t77.R, metalness 0, AO 1. Tangent-space normal XY adds t79 and object normal t76, with reconstructed Z components multiplied. Proven · executed Hero_Ice

Its parallax march takes up to 24 groups of four explicit-LOD samples of t78.R. The UV offsets are exactly 1/1024, 1/512, 3/1024 and 1/256, rather than their rounded disassembly text. Height starts at .99; the per-tap step is (1/1024)*(10+100*lod)/ParallaxScale*(-view.z). The selected UV precedes the first height hit. Spatial checks distinguish this march from a surface without parallax. Proven · 5 spatial cases

MAD_IceBrick shares the ice colour mix but omits the object normal and parallax march. Proven · executed permutation

MAD_Tex1_UniqueNormalGradient adds dirt-controlled A/B/C colour zones to medium and micro detail maps. The triplanar variant samples world-space planes and blends them by the geometric normal; the world-space projection and zone correspondence are traced but the triplanar variant is not executed. Proven · UniqueNormalGradient Observed · triplanar disassembly

MAD_Tex1_UniqueNormal_DiffuseBlend adds an object normal and a separately tiled detail normal by adding XY and multiplying reconstructed Z. Albedo is t75 RGB, roughness is the detail normal t77 A, metalness is object normal t76 B, and AO=1+UseAO*(t78.B*t79.B-1). The masks affect AO rather than establishing a diffuse colour blend from the template’s name. MAD_Tex1_Graffiti_Monster adds a second detail normal, team/custom colour and view-dependent emission; on its placed materials, the relevant colour alpha and EmissivePower are zero, leaving diffuse colour and zero emission.

Family	Behaviour	Confidence
MAD_Road	Procedural painted-road surface driven by material constants and shader pattern arithmetic	Proven · executed spatial cases

Road’s paint is analytic: after its material UV transform, lane = frac((v+LaneOffset)*LaneWidth) >= 1-sat(LineWidth), dash = frac((u+LineOffset)*LineFrequency) >= LineGap, and paint=max(lane*dash,sat(Luminosity)). Colour is (hueColour*paint)^2.2, with a saturated hue-ramp colour mixed toward white by saturation. Roughness is Normal.A, metalness Normal.B times Metalness, and emission is mask red times scale divided by t23. Proven · executed spatial Road cases

The placed Road material has Saturate −1, Luminosity .3, LineWidth .05, LineFrequency .5 and LineGap .5. Its hue colour therefore becomes white, giving linear road colour .3^2.2 ≈ .0707 and white paint. Its Alpha constant is not read by the executed 0x400000 key. Proven · placed constants and executed program

Screens and overlays

The Screens families compute frame = trunc(time*FPS+Delay) mod (columns*rows) when FPS ≥ 1, otherwise zero. The sheet row is reversed so frame zero uses the top row. Screens combines video, logos and a pixel-grid map; Screens_Simple uses video plus a grid. The grid can come from a template default even when no Material property names it. Proven · WARP execution Observed · stored defaults

Screens emits max(grid.rgb)*max(colour.rgb)*EmissiveValue/t23. Screens_Simple uses a roughness constant; Screens uses roughness 1. MAD_Tex1_Screen instead outputs 0.6*sat(t75.rgb)^2.2, roughness .1, metalness 0 and emissive scalar .666667/t23. Proven · executed programs

MAD_Decals1_Graffiti follows Decals1’s roughness remap and metalness, adding a team-colour interpolation and a Fresnel emission term; this emission path does not divide by t23. MAD_SHD_UNLIT_UndergroundBox uses a view-direction vertical gradient between ColorB and ColorA. Proven · executed permutations

SHD_Nat_Veg_Grass_AO multiplies diffuse RGB by 1+AOMult*(COLOR0.a-1), uses roughness 1, AO 1 and specular occlusion .2 in class 4. Its normal binding links a custom texture operator. The stored selector points to the set’s normal slot; this corrects an interpretation based only on an unbound execution texture. Proven · shader formula Observed · operator and selector

What supplies the missing per-vertex and runtime values?

FakeRiver’s scalar, Grounds’ vertex inputs, full team-state updates, terrain-reading templates and exact screen time require their runtime producers. Flat shader inputs establish a formula but do not establish those producers. Unknown
