• The particle system must support the Particle

MBlur map. Particle systems that support

Particle MBlur include PArray , PCloud, Super

Spray, and Spray.

• In the particle system’s Particle Rotation

rollout, in the Spin Axis Controls group, the

Direction of Travel/MBlur option must be on.

• In this same group, the Stretch spinner must

be greater than 0 to stretch the particles as a

percent of their leng th based on the particle

Speed setting.

• The correct type of particle must be used.

MBlur works on all particle types except

Constant, Facing, Metapart icles, and PArray

Object Fragments. Also, in the Standard

Particlescategory,MBlurdoesnotsupportthe

Triangle and SixPoint particle types.

• The material assigned to the particle system

must not be a M ulti/Sub-Object material.

reaches its slowest speed. By default, this color is

an opacity map.

Co lor #2— A particle approaches this color as it

speeds up. As a default, this color is black to

provide transparency in an opacity map.

Typically, you don’t need to change either of these

two colors.

Sharpness—Controls the transparency, relative

to the speed. If Sharpness is set to 0, the entire

part icle is blurry and transparent, no m atter how

slow it is traveling. The default works well in many

cases. Default=2.0.
