Isometric Asset Sheet Generation

Generate consistent sprite sheets for the isometric city game using the GenerateImage tool.

Standard Format

All asset sheets follow this format:

•Size: Square, max width and height
•Background: Solid red (#FF0000), no variation in red tone
•Grid: 6 rows x 5 columns (30 cells total)
•Style: Hyper-realistic
•Lighting: No shadows

Grid Layout

Each row represents ONE complete asset (vehicle, building, etc.):

Column	View
1	Isometric facing North West
2	Isometric facing North East
3	Isometric facing South East
4	Isometric facing South West
5	Special view (varies by asset type)

Special Views by Asset Type

Asset Type	Column 5 View
Airplanes	Gears down, head-first isometric (landing approach)
Helicopters	Top-down rotor view
Vehicles/Cars	3/4 front isometric
Boats	Docked/stationary view
Trains	Front cab view

Prompt Template

code

Using the same format as [reference if available] - red background, 6 rows, 5 columns - I need you to make a new asset sheet with [ASSET TYPE] for my isometric city game. 

Each row should be ONE [ASSET]. The first 4 items should be the [ASSET] isometrically projected 4 times for flying/facing north west, north east, south east, and then south west. The last one should be [SPECIAL VIEW DESCRIPTION].

ALL [ASSETS] SHOULD BE HYPER REALISTIC. [CATEGORY DESCRIPTIONS BY ROW].

NO SHADOWS. [ADDITIONAL CONSTRAINTS]. Full size, 2048x2048 square.

Example Prompts

Airplanes

code

Using the same format as this image - red background, 6 rows, 5 columns - I need you to make a new asset sheet with AIRPLANES for my isometric city game. 

Each row should be ONE PLANE. The first 4 items should be the airplane isometrically projected 4 times for flying north west, north east, south east, and then south west. The last one should be a gears down head-first isometric view.

ALL PLANES SHOULD BE HYPER REALISTIC. Commercial or private jets. First 3 rows commercial airliners.

NO SHADOWS. For the first 4, NO LANDING GEAR. Full size, 2048x2048 square.

Ground Vehicles

code

Red background, 6 rows, 5 columns - asset sheet with VEHICLES for my isometric city game.

Each row should be ONE VEHICLE. The first 4 items should be the vehicle isometrically projected facing north west, north east, south east, and then south west. The last one should be a 3/4 front isometric view.

ALL VEHICLES SHOULD BE HYPER REALISTIC. Row 1-2: sedans. Row 3-4: SUVs. Row 5-6: trucks.

NO SHADOWS. Full size, 2048x2048 square.

Boats/Ships

code

Red background, 6 rows, 5 columns - asset sheet with BOATS for my isometric city game.

Each row should be ONE BOAT. The first 4 items should be the boat isometrically projected facing north west, north east, south east, and then south west. The last one should be a docked/stationary overhead isometric view.

ALL BOATS SHOULD BE HYPER REALISTIC. Row 1-3: small boats (fishing, sailboat, speedboat). Row 4-6: larger vessels.

NO SHADOWS. NO WATER/WAKE. Full size, 2048x2048 square.

Asset Constraints

Asset Type	Constraints
Airplanes	No landing gear (flying views), no contrails
Helicopters	Rotors visible, no motion blur
Vehicles	Wheels visible, no reflections
Boats	No water, no wake effects
Buildings	Consistent lighting angle

Row Organization

Organize rows by category/size:

•Vehicles: Small to large, or by type (sedans, SUVs, trucks)
•Airplanes: Commercial (rows 1-3), private (rows 4-6)
•Buildings: Similar style/era per row
•Nature: Trees grouped by season or type

After Generation

Once the asset sheet is generated:

•Save to /public/assets/ with descriptive name
•Follow the adding-asset-sheets guide to integrate
•Configure in renderConfig.ts with correct row/column mappings

Common Issues

Problem	Solution
Inconsistent sizing	Specify "same size for all assets"
Shadows appearing	Explicitly state "NO SHADOWS"
Wrong projections	Reference compass directions (NW, NE, SE, SW)
Cut-off assets	Add "centered in each cell" to prompt
