■ How to connect
・ 1 section: Arrange X by 360 cm (7 sections are lined up to make sure that no seams appear)
・ When continuing one section in a branch: Place it X±810 cm from the origin of the branch, and arrange it 360 cm from there.
■ Size (actual size)
・Tunnel: 5.4m wide (2.7m waterway + 1.35m passage). Pillar spacing 3.6m. Ceiling starting point 2.5m, summit approx. 6.3m
・The water surface is 85 cm below the surface of the passage. The face of the passage is 0 height.
・Stone bridge: Width approx. 1.8m, handrail height 80cm
・Side hole: Width 1.5m, height 2.05m. Sluice gate and waterfall opening: width 2.4m, height 3.2m
・Stairs: 2.2m wide, 14 steps (1 step 18cm) climb 2.52m
■ Camera Angle
・Overall: Panoramic view from the passage / Line of sight of the water surface / Sluice gate from the bridge / View of the stone bridge / Stone bridge from the hall / Ascending stairs / Waterfall of steps / Side hole of iron bar / Sluice gate / Looking up
・ 1 section and side hole: oblique / straight / looking at the surface of the water
・ Branch: Stone bridge / From the hall / On the bridge / Up stairs / Looking up
■ Where I built it
・Ceiling: A cylindrical ceiling with stone steps lined up along the arch. Branching is a cross ceiling with diagonal ribs and keystones
Drainage grooves on the walls of the channel: stone frame of arch and iron lattice, receiving stone
・Terraced waterfall: Water falls down three stone steps that fill the width of the channel, and white bubbles underneath
・Sluice gates: pointed iron lattices, hoists, pulleys, chains
・Small boat: There is a stool and a bottom plate, and the tip of the boat is connected to the wall with a chain.
・All textures are original. No characters are used
■ About line art (LT conversion)
・ Steps and chamfers are made according to the line extraction to prevent dotted lines and interruptions.
・ The example of the line drawing shown is made in Blender. The way the line comes out is slightly different from the LT conversion of the CLIP STUDIO.
・ If you make the canvas large (width 4000px or more) and extract the lines thinly, it will come out beautifully.
■ Approximate number of polygons
・Overall: Approx. 31,000 triangles / Branch: Approx. 17,000 triangles / 1 section: Approx. 2,300 triangles / Side hole: Approx. 2,700 triangles
■ Please note
・ The introduction image is an image drawn with Blender. CLIP STUDIO's 3D display changes the direction of light and the way shadows appear.
・The flame of the torch does not glow (it is a colored shape). Water does not move (it is a colored surface)
・Since it is a background seen from the inside, the outside of the building is not made. 1 There is nothing beyond the cut of the compartment and branch (hide side by side)

■ セットの中身(3D素材 4点)
・城の地下水路(全体)……全長30.6m。水路と両側の通路、十字の天井の分岐と石橋、横の広間と上り階段、奥の水門と巻き上げ機、反対の端の段の滝、鉄格子の横穴、排水溝、鉄のはしご、小舟、樽、木箱、松明
・城の地下水路(1区画・つなげる用)……長さ3.6m。柱・松明2つ・排水溝2つ
・城の地下水路(1区画・鉄格子の横穴)……長さ3.6m。片側の壁に鉄格子の横穴
・城の地下水路(石橋の分岐)……長さ12.6m。分岐と石橋、横の広間、上り階段
■ つなげ方
・1区画どうし:Xに360cmずつずらして並べます(7つ並べて継ぎ目が出ないことを確かめてあります)
・分岐に1区画を続けるとき:分岐の原点からX±810cmの位置に置き、そこから360cmずつ並べます
■ 大きさ(実寸)
・トンネル:幅5.4m(水路2.7m+通路1.35mずつ)。柱の間隔3.6m。天井の起点2.5m、頂上約6.3m
・水面は通路の面より85cm下です。通路の面が高さ0です
・石橋:幅約1.8m、手すりの高さ80cm
・横穴:幅1.5m・高さ2.05m。水門と滝の開口:幅2.4m・高さ3.2m
・上り階段:幅2.2m、14段(1段18cm)で2.52m上ります
■ カメラアングル
・全体:通路から全景/水面の目線/橋から水門/石橋を見る/広間から石橋/上り階段/段の滝/鉄格子の横穴/水門/見上げ
・1区画と横穴:斜めに/真っすぐ/水面の目線
・分岐:石橋/広間から/橋の上/上り階段/見上げ
■ 作り込んだところ
・天井:石の段がアーチに沿って並ぶ筒の天井。分岐は対角のリブと要石のある十字の天井
・水路の壁の排水溝:アーチの石の枠と鉄の格子、受けの石
・段の滝:水路の幅いっぱいの石の3段を水が落ち、下に白い泡
・水門:先のとがった鉄の格子と、巻き上げ機・滑車・鎖
・小舟:腰掛けと底板があり、舳先を鎖で壁につないであります
・テクスチャはすべてオリジナルです。文字は使っていません
■ 線画(LT変換)について
・段差や面取りを線抽出に合わせて作り、点線や途切れが出にくくしてあります
・載せている線画の例はBlenderで作ったものです。クリスタのLT変換とは線の出方が少し変わります
・キャンバスを大きめ(横4000px以上)にして、線を細めに抽出するときれいに出ます
■ ポリゴン数の目安
・全体:約3.1万三角形/分岐:約1.7万三角形/1区画:約2300三角形/横穴:約2700三角形
■ ご注意
・紹介画像はBlenderで描画したイメージです。クリスタの3D表示では、光の向きや影の出方が変わります
・松明の炎は光りません(色の付いた形です)。水は動きません(色の付いた面です)
・中から見る背景なので、建物の外側は作っていません。1区画と分岐の切り口の先には何もありません(並べて隠してください)
