crypto object AOV not working with particle instanced geo

[John Roberts-Cox]

We're getting an issue with the crypto_object aov where the nuke 
cryptomatte node doesn't generate a matte for the picked colour. The 
maya scene contains particle instanced geometry of tents in a field, 
they all have alShaders on and the crypto_material aov is behaving 
correctly.

Specifically Blue change has values way above 1.0 on output from Nuke Crytomatte node (values fine in aov_image) 

Just wondering if this is a known issue with particle instances maybe?

Values way above 1.0 in the blue channel of the keyer are normal and this actually indicates that things are working correctly. The fact that this value won't generate a matte indicates a problem on the Nuke side.

Not that I know of.

More relevant may be the version of AlShaders and the Nuke plugin you're using.

That's two versions behind, there's an rc19 now, and several Cryptomatte issues were fixed in both versions since then. 

 

 

nuke cryptomatte gizmo - version 7.0 v10

That is the version of Nuke you're using, not the version of the Cryptomatte plugin. In any case, I'd recommend upgrading to the newest nuke plugin first, and if that doesn't fix it, upgrade your AlShaders version.
