### Remarks

This property only has effect when [\_freeformStretching](/engine/6000.7/script-reference/unityengine/particlesystemrenderer/freeformstretching.md) is enabled. When [\_freeformStretching](/engine/6000.7/script-reference/unityengine/particlesystemrenderer/freeformstretching.md) is disabled, particles are always rotated based on the direction they are stretched in, even if [\_rotateWithStretchDirection](/engine/6000.7/script-reference/unityengine/particlesystemrenderer/rotatewithstretchdirection.md) is false.
