渲染

The Render Panel controls how particles appear when they are rendered.

Note

Cycles supports only Object and Collection render types.

• Scale
• Todo.
• Scale Randomness
• Todo.
• Material
• Set which of the object's materials is used to shade the particles.
• Coordinates System
• Use a different object's coordinates to determine the birth of particles.
• When disabled, the emitter is no longer rendered. Activate the button Emitter to also render the mesh.

Halo

Halo are rendered as glowing dots or a little clouds of light.Although they are not really lights because they do not cast light into the scene like a light object.They are called Halos because you can see them, but they do not have any substance.

The Path visualization needs a particle system orKeyed particles.

• B-Spline
• Interpolate hair using B-splines.This may be an option for you if you want to use low Render values.You loose a bit of control but gain smoother paths.
• Steps
• Set the number of subdivisions of the rendered paths (the value is a power of 2).You should set this value carefully,because if you increase the render value by two you need four times more memory to render.Also the rendering is faster if you use low render values (sometimes drastically).But how low you can go with this value depends on the waviness of the hair (the value is a power of 2).This means 0 steps give 1 subdivision,1 give 2 subdivisions, 2 —> 4, 3 —> 8, 4 —> 16, … n —> _n_2.

Timing

Reference

• Absolute Path Time
• Path timing is in absolute frames.
• End
• End time of the practical path.
• Random
• Give the path length a random variation.

• Instance Object
• The specified object is instanced in place of each particle.
• Global Coordinates
• Use object's global coordinates for instancing.
• Object Rotation
• Use the rotation of the object.
• Object Scale

Collection

Reference

• Instance Collection
• The objects that belong to a collection are instanced sequentially in the place of the particles.
• Whole Collection
• Use the whole group at once, instead of one of its elements, the group being displayed in place of each particle.
• Pick Random
• The objects in the group are selected in a random order, and only one object is displayed in place of a particle.Please note that this mechanism fully replaces old Blender particles system using parentageand Instancing Verts to replace particles with actual geometry.This method is fully deprecated and does not work anymore.
• Global Coordinates
• Use object's global coordinates for instancing.
• Object Rotation
• Use the rotation of the objects.
• Object Scale
• Use the size of the objects.

Use Count

Reference

Use objects multiple times in the same groups.Specify the order and number of times to repeat each object with the list view that appears.You can duplicate an object in the list with the Plus button,or remove a duplicate with the Minus button.

• Parents Particles
• Render also parent particles if child particles are used.Children have a lot of different deformation options,so the straight parents would stand between their curly children.So by default Parents are not rendered if you activate Children.See .
• 未诞生
• Render particles before they are born.
• Died
• Render particles after they have died.This is very useful if particles die in a collision Die on hit, so you can cover objects with particles.
