I've been working for some time on this plugin to help make & animate characters with working animation trees. Currently I'm having issues with my Character Preview section, wherein I need to have the StateMachine in the AnimationTree on a character play a certain state's animation in a certain direction. Whenever I try to get it to play using start(state_string), the error in the images pops, and I'm having a hard time tracking down what's causing the error. I'm not sure how to read the CPP file in the engine to trace the problem back to the source in the Engine, so I'm hoping someone here can help.
It may be worth noting that this only seems to happen when I'm creating a character in fewer than the full 8 directions that the plugin supports. Thanks in advance for any assistance.
