What happened to ParticleSystem.textureSheetAnimation?

Hi,

I'm trying to setup textureSheetAnimation as described in http://docs.unity3d.com/ScriptReference/ParticleSystem-textureSheetAnimation.html.
Copy pasted code, but I get "'ParticleSystem' does not contain a definition for 'textureSheetAnimation'.

From http://docs.unity3d.com/ScriptReference/ParticleSystem.html I can see the ParticleSystem should have a varaible named textureSheetAnimation, but nope?

What am I missing? I'm running 5.2.3f1.

Thanks

 

seeing the same thing here...

 

Glad to know it's not just me.. Misery loves company, right'?
