In order to inverse the value red by my billboard set on VellocitySperoidalAlign, I created a VelocityAxis field and said that VelocityAxis = Velocity * -1;
All it does is rotate my billboards 90° and it doesn't allow them to orient with the Velocity axis anymore.
Is there a way to flip my billboards other than VFlipsUV wich flips them only verticaly ?
I also tried to rotate them -180° but nothing seems to change.
Thanks in advance.
