Open-World Procedural Jungle

VIDEO_WALKTHROUGH, VIDEO_QUICK_START

This pack is designed to create fast and easy, huge open-world palm jungles in Unreal Engine 5. It contains everything you need to create a beautiful jungle ecosystem, from different types of palms to bamboo, grass, fern, rocks, etc. The landscape auto-material comes with automatic slope variation and with 12 layers, to help you paint textures like: cobblestone, dirt, mud, sand, cliff, etc. The automatic landscape material is designed in such a way that for all 12 layers, there are 2 level of details: one level which is very detailed, when the player is closer to the texture and another one which is less detailed, when the player is further away from the texture. This way, the player will always see the right amount of details, as it is natural.

The pack contains 1 Overview map and 3 example maps with different lighting setups for different time of days and moods. The example maps are created with real-world heightmaps, 8k and 4k resolution. Two of the heightmaps have a surface area of 25 square km and the third has a surface area of 100 square km. . Everything is well optimized, the foliage has 4 or 5 LODs, the rocks are nanite enabled, and all the big plants have billboards so they are very cheap from the resources consumption point of view.

The assets are as optimized as possible but, let's not forget that Lumen is real time global illumination system, so for lower end computers, there will be performance issues. For those cases I recommend the following changes into Project Settings - Rendering:

1. Disable Lumen

2. Disable reflection or change it from Lumen to Screen Space

3. Replace Virtual Shadow Maps with Shadow Maps (this alone will give you at least 10-15 fps more). As soon as foliage will be nanite enabled in Unreal Engine, all those optimization issues will disappear.

On the other hand, if You want to use the pack at it's full potential, I recommend using Lumen. In order to enable Lumen (if it is not already enabled) you should go to Project Settings/Engine/Rendering and make sure you have the following setup:

1. Dynamic Global Illumination Method - LUMEN
2. Reflection Method - LUMEN
3. Shadow Map Method - Virtual Shadow Maps

This pack works perfectly with any type of landscape (designed in Unreal Engine with it's built-in tools, or created from a heightmap or with alpha brushes)

This pack is the perfect tool to texture and populate with foliage your huge open world tropical landscape

This pack works very well in combination with Open World Template (for those willing to add day-night cycle or dynamic weather system to their open-world game)

This product supports Lumen for Unreal Engine 5.0+ . 

For very realistic results, I recommend using this pack in combination with a real-world heightmap/landscape
