How to change the landscape of the game in runtime

how to change the landscape using blueprint

That’s definitely not enough information for anyone to help you with whatever you’re trying.

But I’ll try anyway. Do you want to edit the height data during runtime? That’s not possible without changing the engine code as far as I know. Or do you want to change the landscape material?

Hey i am interested in this aswell. Do you have any idea on how to change the material of the landscape on button click e.g.?
I want to switch between different landscape materials, but found no clear solution. Please help!

that’s real easy, setup your material with parameters, create an instance of it, create a blueprint with a variable referencing your landscape, build a dynamic material instance and use the blueprint to change all the parameters at run time
