hi there here is a workaround for cryptomatte for tyflow v0.16132
if you are using arnold 5.6.6.0 as u can see there is no need to anything.. it works perfectly fine ...
i used a simple scattering preset for the test scene ... also test with basic voronoi
now real problem comes with vray (Vray5 Update 2.1)
as u can see no crytomatte...
and somehow i figure out a work around..
here is how to ..
after finishing what you are doing in tyflow.. just export "planes" as referance obj.. if u did emit 200 particle... then just export 200 planes.. it does NOT need animation sequance.. just export as frame 0 to 0 ...
and voila.... you got your mattes.. now.. another thing is NEVER make those plane "invisible" or "hide".. just carry them where your cam doesnt see...
in the end you got every object with cryptomatte..
