When I use HDA get landscape from unreal to houdini, The layer will missing. It will keep only the height and mask layers.
The Layer01 and Layer02 will missing.

After the data exchange, the new landscape Y axis scaling of half, But in houdini, the Y axis is normal. Due to missing layer information, the new landscape can't get the material in unreal.

This is from Engine document:
"a heighfield: the landscape data will be converted to a heightfield 2D volume. All landscape layers will also be added as masks to the heightfield." Did I misunderstand?
