i want to maje the snow fallin the snow area of the map its larage so it will take time if i placed the fx all around the snow by myself
Yes, placing lots of objects is one of the annoying parts of level design.
It’s possible to build editor blueprint utilities that can place objects in a grid; you might want to look into something like that?
sure but is it possible to make it only snow in the snow biome
Yes, it is possible to make it snow only where you want to make it snow.
The easiest way to do this would be to create some kind of volume actor that you size to cover the areas you consider being snow biome, and then use this volume as a constraint on where you spawn snow particle emitters.
For fancier solutions, you first need to define what you even mean by “snow biome” – how do you define a biome in your level?
If it’s “painting the terrain with a particular layer,” then you will probably want to query the terrain for the layer at location across some kind of grid, and spawn emitters at the places where the query says the particular layer is used.
If you use some other mechanism to define what a “biome” is, then you’ll have to appropriately tie into whatever that system is in a similar way.
ye snow biome is painted in white layer in the landscape
so i create blueprint class , actor then i put a box collusion ?
i never tried to do the query method , so i dont have many info about it can you please explain it for me and how to do it
