Houdini heightfield layer and height resolution is same. But unity heightmap resolution need be 2^n + 1 and splatmap need be 2^n. How to deal with these issue? Use 513 heightmap and 512 splatmap works in unity, but in unity new terrain tool, when preview the splatmap, it prompt that the splatmap should be 2^n. Thanks.
You can use the Volume Resample node to set the size of a specific Heightfield layer without affecting the height layer. So you can have height at 1025 and splatmap at 1024 or 512 for example.
