# FAQ
### **What version of Unreal is supported ?**
Only Unreal 5.5+ is supported.
### **What plugins are needed ?**
The PCG plugin is needed, as well as editor scriptable blueprint tool framework, both Unreal built-in plugins.
### **But why not just foliage tool ?**
Unlike foliage tool, this system execute a PCG graph, which allows you to have custom scattering rules ( grass around rocks, certain density and scale on certain meshes, etc. )
It allows also to have info on the surrounding objects ( normals, object types etc. ), which can be used to scatter meshes like ivy on vertical wall, certains meshes on certain objects etc.
It can also be easily injected in other PCG system using the get ActorData node ( biomes, etc. ).
### **Does the painted PCG graph has limitations ?**
Not really, it's a regular PCG graph, but you need to keep it as fast as possible unless you'll feel a lag in the painting process.
The whole graph is executed on all painted points on each brush strokes ( on each root point addition ).
### Can it be used at runtime ?
No, 100% editor only tool.
### Do you accept custom feature requests / graphs or PCGPainterActor creation ?
I do, if needed, feel free to send an email to ****.
