Small Fixes: +"Orient Search Radius" set to Zero defaults to Oriented Bounding Box mode. (useful if Orientation fails for flat objects) +"SRT Size" set to zero makes SRT unselectable.
I just replaced the previous files ( "sop_lattice" and lattice_b_core" ) in the "C:\Users\...\otls" folder, but strangely enough I get a "missing the parent of a node on load..." error message when loading a scene where I used the previous 1.2 version.
If you removed the older versions of the asset, this is the expected behaviour. But you can activate the asset definition toolbar and select the new asset definition afterwards. After a save, the error should be fixed.
