Mudbox to UE4 terrain height map problem, please help!

dmilligan277

Hi everybody,


I am trying to bake out a terrain height/displacement map from Mudbox and bring it into UE4 but I am having a problem in that the height map produced from Mudbox does not appear to have white/black range and is producing a much flatter terrain in UE4 than the original in Mudbox


I have tried many different settings in the bake and all are not giving the results I want. I even tried baking out from Xnormal and is is getting the same result...not enough depth in the baked heightmap


Any help on this issue would be massively appreciated.

Can't you simply adjust the depth in UE4?

Can you? Do you know where I can find that setting in UE4? I was hoping that it was some simple thing to do with the bake settings that maybe I missed, because even the colour range on the heightmap doesn't look right seeing as the terrain has quite a bit of depth in Mudbox.

Cheers for the speedy response btw.

Here's the wiki entry for working with landscape heightmaps and world machine, some additional setup in the creation process is needed for parity.

Thanks for the link Futzy but it doesn't really give info to help with my issue. I simply need to find out why my height map bake from Mudbox is not baking out with the correct depth range.

The baked out height map should have much more contrast as there is very high parts to the terrain and very low parts. Any more ideas?

Bring your terrain to world machine and set the elevation to your desired height altho I would not recommend going over 1310 meters. Then bake your heightmap as RAW16 file.

EDIT: You can also bake your terrain in Xnormal. With default heightmap settings it should give you the correct height.

I would assume so but I'm not really an unreal expert.

It looks like there are scale parameters when you import: https://docs.unrealengine.com/latest/INT/Engine/Landscape/Creation/index.html#importingaheightmapandlayers

You might be able to scale after the fact too, I assume simply scaling the terrain object would do it but I dunno.

Your height map looks about as expected to me.

Ok so i figured it out, well a way around it anyway. When i imported the heightmap into UE4 i simply increased the Z scale to 390 instead of 100 and that seems to have done the job.

Thanks for the advice guys.
