This is amazing! Incredibly great job on this. This has everything I had wished TIFA had - and more. Only thing I could think to add is VSF animations (which I see are already planned) and FOV settings for the camera.
As for Bugs/Feedback, under "Light Settings", direction doesn't seem to be working, though that could just be a bug on my end. (?) I'll also add that the color options under "Render Settings" may be better suited under "Light Settings" but that's fairly trivial. (I assume it's the equivalent of VSeeFace's "ambient" lighting.)
Once again fantastic work, I can't convey how great of a job you did here.
Edit: One other thing - Diffusion under "Bloom Settings" doesn't seem to be saving for me after the program closes.
