Get Landscape Heightmap of Static Mesh Surface

[Das_Biest_3000]

@Majj_1089 Thx for your help, really appreciate it:)
For your import of the monkey can you send me the import landscape settings too?
I was able to create better pngs now, but when i want to import them, i need lots of total components for the best resolution and all above 1000 components its crahes and i cant fix this issue:

I tried also the monkey but with 4096x4096 png, i set my landscape import settings to Number of Components 256x256 to get max resolution and Sector Size 7x7 Quads, cause the components getting smaller. But with those settings i always get near to the 10k components of my landscape and then UE always crashes cause its not able to rebuild all those actors in my project. Now i dont know how you get the monkey head with so much resolution.
Thats my png for the ape:

Thats weird, the resolution of my png here in the message is worse, and the original file is better:

I added some pictures to show you my problem:

1. perfect resolution preview of the monkey head

2. lower resolution

3. bad resolution

4. your settings

I cant start the import of the 1. Version or the other cause the total components are really too much over 60k. Only your version is possible with 256 components but the resolution is not like yours do you know why?
