Nanite Landscape and Material problems in 5.6

[85.Martin]

Hi,

I am trying the new 5.6 and run in a number of issues updating my 5.5 project.
My Landscape seems to be broken. It does run fine in standalone but in editor chunks keep disappearing. If I disable Nanite on the Landscape it seems more stable again. Is there a Landscape/Nanite optimization in 5.6 that I need to fix in my project or is this a bug?

I also found a number of material issues I did not encountered in 5.5. Is this a new optimization in 5.6 that I need to fix in my Landscape material or is that a bug? Seems like the “Overlay Blend” function is not working correctly but was not replaced with a new one for 5.6.

Anyone else run into similar issues?

Thank you

Hi there Martin. There seems to be a problem with this Nanite when using landscape in 5.6.
It seems to do something with the build data.

I reported a same problem here:

UE 5.6 landscape (nanite) build, lots of bugs and problems

Hi, Problem 1 If make any changed to the landscape and build the nanite data in editor all is ok but in stand alone game all tessellation is gone. [UE5.6 problem1] Problem 2, critical The landscape I made in UE 5.5 after build the nanite it bugged out. Same happens if make new one from the heightmap the editor exports for us. After many hours of trials and fails I found out that this happens if the quads of the landscape size is not equal, like 505x505 (default). UE 5.6 export…

hey guys, in 5.6 if u just create empy landscape and enable nanite your landscape breaks. 5.6 nanite landscape is broken. Just tested on 5.5 it works faster and no error
