Why is my landscape height map importing super tessalated?

I actually have two questions:

  1. Can UE5 not import 32-bit images? I can’t find anything in the documentation that states such a limitation or find any posts about it. I’m wondering if this might have to do with why my landscape is importing super tessellated.
  2. When I import my landscape with a 8,000x6,129 16-bit PNG exported from Blender, I get this result:
    image
    image1920×1053 89.3 KB

At first, I thought this was the actual geometry, but I can use the landscape brush to smooth it out manually just fine. Does my image need more pixels? (8k is already pretty massive). Can I smooth out the entire landscape at/post import?

Thanks in advance for any help! <3

I discovered that blurring my height map fixed the issue, so it seems that it’s not an issue with Unreal, but it would be pretty nice to have this as a feature to adjust the blur at import. Regardless, I’m just happy I found a solution. Leaving this up for anyone else that runs into the same issue.
