Like the title states. I am trying to manipulate the landscape material with foliage actors added to the material. At the moment I have the material set up with the wanted foliage actors to be distributed based on the material and I’ve been able to control the landscape material parameters at run time by using a Material Parameters Collection. While the parameters do change during run time i’m running into an issue where my grass map isn’t being updated so the foliage stays in the same place no matter if i change my parameters and texture placement of the landscape material. It only recalculates the grass map when the original material or material instance is saved or “updated”… (in the editor) this successfully leads to the outcome i’m looking for…all foliage disappearing and reappearing in it’s new location.
I’m currently still looking into this and will be backtracking to see if i made an error…any help figuring out whether this is possible is appreciated.
