Overview - Maps
The pack includes a dedicated Overview Map that clearly presents all assets and their variations, allowing users to quickly explore the full content of the environment. A separate Buildings Map showcases a wide range of premade modular building assemblies, demonstrating how assets can be efficiently combined to create complete Spanish Revival House structures.
Additionally, the pack features two similar fully prepared environment maps and asset ecosystem: a 2 km² map, ideal for smaller projects, fast iteration, and cinematic production, and a massive 16 km² open world map, designed for large-scale games, expansive exploration, and high-end cinematic scenes. Both maps provide a ready-to-use foundation for immediate production.
In order to see the Maps clearly in the content folder, please enable Procedural Content Generation plugin and Water plugin from plugin tab.

Overview - Modular Kit
The modular architecture kit is built on a precise 16 cm grid system, fully aligned with Unreal Engine’s power-of-two grid standards and optimized to match character scale. This ensures seamless snapping, perfect proportions, and effortless assembly. All modular pieces are designed to work flawlessly together, allowing users to quickly create a wide variety of authentic Spanish revival Houses— from small town houses , pools , tennis courts. Each architectural module has been carefully crafted with a consistent Central Spanish Revival Architectural style, ensuring visual harmony across all building types while maintaining maximum flexibility and creative freedom.
To fully utilize the modular system, we recommend adjusting the editor grid settings. Go to Editor Preferences → Grid Snapping and enable power-of-two grid sizes such as 4, 16, 32, 64, 128, and 256 cm. This allows all modules to snap perfectly into place and enables users to assemble complete buildings and architectural layouts within minutes.
This modular workflow dramatically accelerates production, making it easy to create unique, large-scale environments with professional speed and precision.
Overview - Trees
The landscape is inspired by the diverse scenery of the California coast landscape , combining mountain areas, rivers, coastal cliffs, and beach environments within a large-scale playable landscape.
A wide variety of detailed photogrammetry foliage is included, such as:
-
Monterey Cypress
-
Sagebrush
-
Date Palms
-
Coyote Bush
-
Yucca Plants
-
Palm Trees
-
Mediterranean Cypress
-
Banana Plants
All trees are fully optimized for Unreal Engine 5 with Nanite support,
The leaves are mesh cards using tightly fitted masked materials, so alpha overdraw is kept relatively low. In our current scenes, Nanite overdraw is not the primary performance bottleneck. Profiling shows that the larger limitation, especially in recent UE versions with large foliage-heavy environments, is on the CPU/Game Thread side rather than Nanite rasterization itself.
Each asset also includes Pivot Painter 2 integration, enabling realistic wind animation and natural foliage motion.
Tree assets feature high-quality geometry with triangle counts ranging from approximately 300,000 to 1,000,000 triangles, delivering cinematic-level detail suitable for close-up shots, next-gen games, and large-scale open worlds.
Overview - Wind Effect
All tree and plants wind animations are fully controllable through the centralized MPC_WindTree Material Parameter Collection / MPC_WindPlant, providing global control over wind intensity, direction, and behavior. To access these settings, simply search for “MPC_WindTree”/ ''MPC_WindPlant'' in the Content Browser. This allows you to adjust the wind parameters of all tree and plant assets simultaneously, ensuring fast and consistent environmental control across your entire scene.
By default we have set distance for WPO for all foliage and PCG for performance concern. In order to increase disable distance for WPO, please check foliage tool and PCG both by typing
To enable Wind in project, select the MF_WindEnable Material function from content folder and tick the ''WindEnable?'' node inside the Material as stated above. Please be aware that Pivot painter wind (WPO based Wind) causes FPS drop in the scene.
Ocean
Please enable Water plugin to use our Ocean Material properly.
Ocean Material consist of 3 vertex paint layers :
Black Channel : Base Ocean
Red Channel : Deep Waves & Foam
Green Channel : Shore Waves & Foam
Landscape layer setup
-
Go to the landscape folder in content browser and select the MI_MM_Landscape. Drag it to the landscape details panel material input.
-
Go to the Landscape Editor, from paint tab, create landscape layer info for each landscape layer.
-
After these steps landscape material is applied to the landscape.
Landscape Grass
Grass Mesh
You can change the grass model by dragging and dropping any Static Mesh into the Grass Mesh slot.
Grass Density
The Grass Density parameter controls how many grass instances are spawned.
Higher density creates a fuller look but reduces performance. For better performance, use lower density values.
Scale X
The Scale X parameter controls the size variation of the grass meshes.
Increasing the value makes the plants larger, while decreasing it makes them smaller. This helps create more natural variation.
Distance Field and Dynamic Shadows
Enabling Distance Field Lighting and Cast Dynamic Shadow improves visual quality but increases performance cost.
For better performance, disable both options and enable Contact Shadows in your Directional Light instead.
Instance World Position Offset Disable Distance
This parameter controls the distance at which the World Position Offset (wind animation) is disabled.
Lower values improve performance because World Position Offset and Nanite both add rendering cost.
However, decreasing this value also reduces the visible wind animation distance on the grass.
PCG_Procedural Content Generation
In order to use PCG Volumes in the scene, Procedural Content Generation Plugin should be enabled in Plugin settings.
PCG_BaseGrass Volume + BaseGrass Layer paint
PCG_TreeGround Volume + TreeGround Layer paint
PCG_Tropical Plants Volume (No layer paint needed)
PCG_Tropical Plants2 Volume (No layer paint needed)
PCG_CliffPlants Volume (No layer paint needed)
The PCG (Procedural Content Generation) system can be found inside the Content Browser under the PCG_Assets folder. This system allows you to procedurally generate vegetation over landscape.
If the Procedural Content Generation (PCG) Volume reduces performance while you are editing the scene, you can disable automatic regeneration.
Go to the PCG Details panel, turn off Regenerate PCG Volume in Editor, and set the Generation Trigger to Generate On Demand.
With this setting, the PCG will only generate content when you manually trigger it, preventing performance drops while you sculpt or paint the Landscape.
Whenever you want the PCG to update according to your latest Landscape changes, simply press the Generate button. The PCG will then place trees and vegetation based on the updated Landscape.

Performance Tips
Foliage Performance Optimization
The following settings can help improve performance when using dense foliage and landscape grass in large environments.
1. Disable wind animation at far distances
Wind animation using World Position Offset can be expensive when applied to large amounts of foliage.
To optimize this, open your Landscape Grass Type asset and set:
Instance World Position Offset Disable Distance
This disables wind animation for distant foliage where the movement is no longer noticeable, reducing unnecessary vertex calculations.
2. Disable dynamic shadows for grass
Dynamic shadows on dense grass can have a significant performance cost.
Inside the Landscape Grass Type settings, disable:
Cast Dynamic Shadow
Grass usually does not require full dynamic shadows, and disabling them can greatly improve performance in large outdoor scenes.
3. Use Contact Shadows as a lightweight alternative
To maintain subtle shading after disabling dynamic shadows, contact shadows can be used as a lightweight solution.
Select your Directional Light and set:
Contact Shadow Length = 1
Contact shadows help create small local shadow details near objects, providing a convincing shading effect without the heavy cost of full dynamic shadows.
Result
By applying these optimizations:
-
Wind animation is disabled for distant foliage
-
Expensive dynamic shadows on grass are removed
-
Lightweight contact shadows preserve visual depth
These changes can significantly improve performance in foliage-heavy environments while maintaining a natural visual appearance.
