Hi,I try to import a landscape from houdini to UE,It's correct when I used HDA in unreal,but it will be clipped when using top to import in UE(hdaprocessor,filepattern,geoimport).I kown Unreal has limit of height in +-256m(At zscale=100),but it's still wrong as I
minimize the landscape size(no clipped but wrong res),looks like the resolution on z has been resized(see the pic).So how can I solve this kind of question ,or is there something wrong during these steps.

i'd say something is wrong in your scene.. the terrain Z resolution is fine for me. i've exported with and without the min max attribs and with / without a TOP compiler and all have worked as expected. i'm in ue5 / latest daily build, so of course there could be issues with different houdini builds, but this one is working for me...
