Why are my imported landscapes being skewed along the Z axis?

Hello, I’ve been trying to follow some tutorials on importing a heightmap from world machine into ue4 but for some reason my landscapes are consistently skewed in the vertical Z plane.

I set my World Machine resolution to 1009 in the attached screenshots, export to raw16, and do an import in UE4 and what is fairly flat terrain turns into extremely steep and high mountains unless I really scale the Z axis down on the landscape actor. Any ideas?

Hi,
I’m just struggling with this issue myself: what I’ve found is that you should set up general setup for World Machine “Projects Settings/General Setup” with maximum elevation 655.34 and minimum elevation -655.34.

Then setup your world machine project to stand between those values, that are maximum elevation for Unreal Landscape.
Try to stick with that and it will be good. I hope. :smiley:

Peace,

And I think I’ll go with a tutorial for this, there’s not much about UE4->World Machine → UE4 workflow around.

awesome, thanks! I will go try this after work today, I was sort of heading down this path but I failed to set the base elevation to -655 instead of 0.

Hmm i have the inverse effect where mine shrinks I will try this now as well.

That’s sound strange, try to edit Base Elevation first and do not touch the slider. It should work like a charm.

Sorry no I just meant I had not tried adjusting Base elevation yet. Does the width and height values matter? Right now I have them set to 8km.

The only thing that matters is resolution for the heightmap you’ll export from world machine: 4033x4033 or else. Follow the table on Landscape manual and you will be good to go. Tomorrow I’ll post a complete guide on how to have the terrain matching perfectly to World Machine HM and vice versa. :smiley:

Remember when I told that size doesn’t matter? I was wrong. Actually you MUST adjust the extent of your world machine doc to match the size you want in Unreal. So, with 505x505 landscape you must adjust the extent of world machine document to 505m

Aha! I haven’t had a chance in last day to play with this, glad you are making progress, keep us posted!

I’ve a perfect match :smiley:UE4 to World machine

I’m stuck with this too. Any tutorial of World Machine and UE4 workflow that avoid this Z scale issue :?
