Particle Group > Rotation Group

The Rotation group rotates the particles on any axis. You can give the particles a random rotation so they rotate in different directions, and orient the particles in very specific ways.

Rotate X, Y, Z

Rotates the particles around the X, Y and Z axes. These parameters are mostly for the Textured Polygon particle type.

• Rotation X: Sets the rotation around the X-axis. Only enabled for Textured Polygon.
• Rotation Y: Sets the rotation around the Y-axis. Only enabled for Textured Polygon.
• Rotation Z: Sets the rotation around the Z-axis. Enabled for Textured Polygon, Sprite and Star.

Left to right, Rotate X at -50 and 100. 

Random Rotation

Adds randomness to the Rotation setting. Surprise! More specifically, this parameter rotates the particle around a random axis. Useful for getting a more natural looking effect where all particles have unique orientation in space.

Rotation Speed X, Y, Z

You can set the particles' Rotation Speed separately on each axis.

• Rotation Speed X: Rotation speed on the X-axis. Only enabled for Textured Polygon.
• Rotation Speed Y: Rotation speed on the Y-axis. Only enabled for Textured Polygon.
• Rotation Speed Z: Rotation speed on the Z-axis. Enabled for Textured Polygon, Sprite and Star.

Random Speed Rotate

Makes the particles rotate at random speeds. Some particles will rotate fast, some slower, which is very useful in giving a natural appearance for the animation.

Random Speed Distribution

Enables fine-tuning of the randomized speed of Rotation Speed. The default value of 0.5 is the normal Gaussian distribution. Setting the value to 1 will give a flat, even distribution.
