Oh I see.
By blueprint, I just mean to design a “piece of jungle”,
so mixing a floor mesh/various trees/rock meshes etc
I currently do that manually with
1- manually places instances in a blueprint
2- automatically creating instances in the construction script
3- adding instances along a spline
But the foliage tool is way quicker with these types of things,
also the whole placement is via Blueprints so I can’t see the final result until I am in play mode.
My whole approach here is not very game-like, that’s why I have to find workarounds.
The user is switching between various designs, so I do that with Spawn/Destroy.
Therefore it has to sit in a blueprint, also since each jungle-block (or each design in general) is normally spawned along the horizon to create an endless drive.
