Update 1.2 : Imposters now work correctly with UE5.

UPDATE 1.1 : Content Update

Trees now have Octahedral Imposters(Billboards) set up.

This bumps the required engine version to 4.26, previous version is still available to 4.25 users.

This contains the full Unreal Engine 4.25.4 project for a procedural forest scene, along with all models, textures, shaders and procedural rules used to create the scene.

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 like in this scene.

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 scene 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
