I pulled myself together and got to blender :)
So this one is my first rough experiment on compositing something 3d into some real-life video / gif, to make futa or giantess or futa-giantess even!!
Next one is already in production ๐
This one is done. I'll never revisit it again, I think it damaged my brain enough ๐ซ
To say it is challenging to me is to seriously underestimate my feelings about it ๐ญ
Mostly it is about placing shadows and and "track" pelvis movement, autotracking can't help in this situation.
I attached blender project, in case anybody want to look it up ๐ฌ
