Yes, exactly, if it's within the dimensions recognized by RPG Maker, the tool will adapt to work accordingly.
And yes, currently each sprite allows the character to look in 3 directions. If you use an 8D sprite, the character won't be able to look to any side when the sprite is standing diagonally. I'll have to write this support to allow the character, if facing directly diagonally, to turn their head to look at any angle other than their back.
It will be a mapping of more sprites, but it will offer many more features and immersion.
