Cryptomatte in HtoA

Does anyone use cryptomatte in HtoA?

I can see ""crypto_asset", “crypto_object”, “crypto_material” AOVs in Mplay, but everything is completely blank.

I connected cryptomatte node to AOV output node in SHOP.

How can i write the information about cryptomatte? Do I have to anything?

I attached a hip file.

Thank you for your help.

The docs are here: https://support.solidangle.com/display/A5AFHUG/Cryptomatte

As noted at the end of the page, Cryptomatte assume an asset naming convention specific to MtoA, but you can override that with the crypto_asset string attribute.

Here's a sample scene: cryptomatte-htoahip.zip

@Frederic Servant this example currently doesn't work in Houdini 16.5.473 and HtoA 3.0.3/Arnold 5.1.1.1.

On loading the all of the shop nodes are stripped out. See below for the errors on load.

Are you able to update it please? I am having issues assigning custom crypto_asset strings to objects among other things and it would be good to see a working example.
