After scouring over the engine code, I am still 100% clueless about how to modify the heightmap at runtime. I realize that I wouldn’t be able to use lightmass for terrain anymore, but my game requires terrain generation at runtime.
Anyone have an idea on how I could approach this? There are very few comments in the source code in respect to Landscapes, nor is there ample amounts of documentation 
Hi MatrixCompSci, have a look at existing forum threads and answershub questions:
AnswerHub “How do I procedurally generate landscape?” (short answer: currently not supported!):
Forum “Does anybody have any experience with procedural planet generation?”:
Wiki “Procedural Mesh Generation”:
And also a nice example of “Procedural Voxel Generation In UE4”:
Hope that help!
Huh…
Is there a way to build the world on a cloud server, and then send that to the player? Or am I stuck waiting for Epic to support it in the engine?
Edit: Sorta like load the heightmap into a pseudo editor on a cloud server, run lightmass/physics prebaking, then send the umap to the player. I understand the networking issues at play here, as I’ve already made a cloud server for AI prebaking. Would UE4 allow for this though
MatrixCompSci, I think that with enough C++ development you could do whatever you want…
But to get some advice from Epic you should absolutely ask your question to the Epic AnswerHub, with enough details, backgroud, and a link to this thread (and back-link it here for future reference).
Cheers!
There is the question I posted
One of the threads you posted claimed it was on UE4’s roadmap. Was it implemented, or taken down?
I decided to implement my own terrain engine, dedicating 3 of my programmers to work on that for a few weeks. I see no other way to do this with the current state of the engine
Hi, so are you going to mod Unreal Engine for your custom Terrain engine? Or are you talking of making your all game engine from scratch?
I am considering implementing my own terrain engine over a class like this: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums, then using compute shaders to manage my LODs
