Can't change the size of particles in particle physics settings I was trying to increase size of particles in a particle system by adjusting the size property in physics settings as seen in the tutorial I was watching.But that setting is not available to me.Could any one tell where I went wrong ? and how to solve it ? Thanks in advance ( Blender v2.79 )
Size is only for particle physic.

The tip value should in most cases be at zero and can cause a weird look if it is to high.
