Hello there,
I’v recently added two features in the Unreal Editor (4.26.2 engine version) working in Foliage mode. It’s so strange Epic has not implemented such a basic feature as Foliage grouping (hope it will change when UE5 is released)
So basically, first feature is an ability to remove all instances of a selected (single or multiple) foliage items from the current world without removing the foliage item itself from the foliage pallete (Watch video: streamable/mryz44)
Second feature is a simple foliage grouping system with dropdown button to cycle through wanted foliage type (Watch video: streamable/tx98er)
All you need to do to have these two features are:
- Source version of UE4
- All modified classes responsible for these changes (https://drive.google/drive/folders/1O_bF1XdMtDw4iITexVv3JyyBZQLMXBQJ)
- Copy and paste downloaded classes where they belong inside the downloaded engine (exact location is in location.txt file)
- Compile / Recompile the engine ( is a tutorial how to do it : https://www.ue4community.wiki/building-engine-from-source-pawl3bqm)
After that, every new or existing project that is source build should have aforementioned features. Of course, if you want to change the names of foliage categories to your own, you must edit SFoliagePalette.cpp file and change names manually e.g from “Grass1” to “MyCustomTrees” etc.
