Fixed a bug that caused loaded curves to disappear after being recooked (but not the first one!).

Fixed editable curves not being created by the plugin.

Fixed tearing issue when round-tripping terrain in an HDA. The issue was caused by corner sampling actually adding an extra voxel to the input data, that then caused a discrepancy in the output terrain size, causing the tearing of the data.

Fixed an issue that caused terrain input layer data to be incorrectly set in Houdini due to sizing inconsistencies.
