Hey @cgrifter , hope you dont mind me chiming in here, but @waylow , I took this course last year and throught the duration , I regularly posted threads on here with the issues encountered on the course. To be fair, most of them were probably my own stupidity or misunderstanding of what @theluthier was saying , however they may be of help to you, to see what aresa of the course were problematic. In particular, I remember there being some issues in the texturepainting parts where Blender had changed a lot since the recordings, and the wing rig wass very tricky, partuicularly with an issue I raised in one of the threads about the wing bones behaving weirdly between tabbing in and out of modes.
As I was a beginner back when I started this course , hopefully the issues I encountered are ones that will generally be issues to all.
Also @cgrifter , have a look at them as they may help you out too as you progress through the course
Finally , I will shamelessly link my own result from the course incase anybody wants a look (note that I haven't done the animation part yet, as I am waiting until I am more competent before attempting it )
