Hello,

When using the mesh orientation vector for facing, I want it to point to the world up vector (0, 0, 1). When I use a very small X or Y component, this works correctly:

However, when I use a purely up vector (i.e., set X and Y to 0), the sprite disappears:

Is this expected behavior that I’m misunderstanding, or is it a bug?

Hi @koromire1,

I believe simply setting the sprite facing to the up vector (0,0,1) will achieve the effect you’re looking for
