Managed to dislodge the surfboard leash pin without popping the leash plug (in relatively small waves, lol). Kind of a pain in the ass to fix but shit happens I guess.
Been trying to work around Blender's lack of Light Linking; learned how to do some neat vector trick to add "depth" to emission shaders and how to create a shadow catcher plane.
Annoying to work around, hopefully they add selective lighting support to Blender soon.
Realized after several months that one of my shape keys in Blender was out of sync and that's why it would deform randomly areas when importing VMDs (previous fix was to copy the old material and link the object data).
