World Composition Crashes Editor

I’m trying to create a a 256 X 256 Tiled World in the world composer.

(using PNG as heightmaps)

And stretching it to the Size of 100km x 100km.

The engine crashes on multiple machines with clean projects when trying to generate the tiled landscape. (Creating a new level and that’s it)

Currently my workaround is a single huge tile with 256X256 components which their textures I Override.

Would like to take advantage of Level Streaming though.

Thanks in advance!

Hey NadavLeap,

Can you provide me with your crash logs, clear steps to reproduce the crash in a blank project, and the tiled heightmap you are using?

I need this information in order to reproduce this issue on my end, and in order to enter a complete bug report. Let me know if you have further questions.

Thank you,

After Revisiting the problem and trying Again With The new 4.15.1 Engine, The World Composition Worked! (Same map Same data).

So I’m marking this Issue as resolved.

if you still wish to have the details you asked for, from the older engine, since it was a Persistent problem, Please provide me with an Email Address to send the Height maps to.

As for the Steps:

Open new Blueprint Project from the launcher (The empty one, with starter content) → Create new level (I picked the one with the skybox) → Saving the level → Enable world composition → Import Tiled landscape and rescaling the X Y Z to fit 100.383 X 100.383 km in my case. (The Z is 300 to fit my Heightmap’s range).

These are the only steps I Made. Crashed every time on multiple machines with 4.14, the Composition worked with no crash on the 4.15.1 Version. will update if something goes wrong across machines and processes.
