Houdini 17.5.193 When you merge a hip file into the current scene (e.g. with hou.hipFIle.merge()) you can specify a node pattern in order to limit the merge to only nodes matching that pattern. When not "*" this would previously filter out the dummy defs and embedded HDAs as well which could cause merge and load failures if the merged nodes rely on those embedded HDAs or dummy defs. Now the needed dummy defs and embedded HDAs are automatically merged into the current scene. If no pattern or "*" is specified then all embedded HDAs are merged in order to retain the old behaviour of merging everything. Mon. March 11, 2019
