In animation, which scale or measure system should I use? For example, If I model an entire room and plan on having a character moving about in it, should all the assets and character be done to real world values or should I use Blender units?
I'm asking this because sometimes when I make a character and scale it down to it's "real size", I sometimes have issues with simulations or hair particles because of the character being to small in the scene. Like having to use very small values to tweak values(example:o.oo5 in particle hair uniform slider instead of 0.5), which sometimes can make tweaking very finicky.
So I wanted to know which is way that is most commonly used.
