Procedural Forest v4.25-4.26

A completely procedurally placed forest with assets, textures, lighting and procedural setup.

UPDATE: By popular demand, here is a video running around in the provided scene using the Unreal FPS template.

The resolution is 1920x1080 and its running on a regular Gefore 1080 graphics card:

This contains the full Unreal Engine 4.25.4 project for a procedural forest scene, along with all models, textures, shaders, project settings, lighting and the map containing the procedural rules.


So why should you get it?


It's great if you want to dissect my work, see how I set up and organize my shaders and build content to be optimized for dense usage. See how I light my scene and configure the project settings for something like this.


Or if you are just looking to get your hands on some AAA-level models and textures, optimized and ready to go for console usage right away!


Within the provided map you will find Procedural Foliage Volumes with accompanying rules, so you can easily see how I went about setting it all up, to create a complete forest scene without placing a single asset manually.


To go along with the asset you will find some smart shader solutions for wetness around the shoreline, cheap dynamic application of snow cover and a water shader with automatic debris gathering around intersecting meshes and shorelines.

And lets not forget what is possibly the star of the show, a cheap way to set up pixel perfect height map based shadows on every mesh, using PixelDepthOffset and Contact Shadows in an unholy alliance!

NOTE: Procedural Foliage is an Editor Preference and not a Project setting. So in order to access and place new Foliage volumes and access the extended settings, you need to go into your Editor Preferences and activate Procedural Foliage.


NOTE2: In order to get the correct lighting if importing into another project, make sure you have the following under RendererSettings in DefaultEngine.ini

r.AllowStaticLighting=False

r.GenerateMeshDistanceFields=True

r.SSGI.Enable=True

r.SupportSkyAtmosphereAffectsHeightFog=True



Asset version: 4.25-4.26
