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
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
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
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
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
