Cryptomatte | AOV where is it?

[Greg Punchatz]

I am finally getting around to trying crypto matte out. We Installed the latest Al_shaders and I don't see the crypto matte in my drop down menu of AOVs in soft, any ideas how to get  to populate the AOV list?

Thanks!

I found my answer...in russian

Well I manually added the AOV s like this image ( http://softimage.ru/forums/lofiversion/index.php/t9933.html )  but no matter which or all Crypto matte AOV I add to my list in soft all I get is a yellow matte for every object in my scene in nuke with no ability to pick objects. I am using Al_Surface material as an override on all the objects in this scene to test with. Anybody have any ideas why this is happening?

Are you looking at the crypto_asset, crypto_material or crypto_object aov?

Asset and material sounds like they would be the same in your scenario.

Also, if you have the newer nuke gizmo it has a layer selection field, what does it say when you plug it in?

Thanks Caron,
Just got the new gizmo installed , now nothing even shows yellow when crypto gets connected and nothing shows up in the layer box. If I push the unload manifest option I get this message  "Gizmo's cryptomatte selection is not valid or no cryptomattes are available. "

I have tried rendering with all crypto AOVS or just one.... 

I am assuming I am doing something wrong on the soft side of things, all the info I can find on how to use it in soft is in Russian. I entered the names of the AOVs manually like in the image above, I made them a rgb color channel (no alpha). All channels are float.  I saw that under the deep tab in soft there are options for cryptomate .. so I tried turn those on.  Cropping exr's is off...


Thanks!

Any more luck with this?  I'm not sitting in front of Soft at the moment, but I don't believe you should have to mess with anything in the deep area to get it to work.  Are you rendering a deep exr?

Next thing I would check is to plug your rendered image into a "view_metadata" node in nuke, and look for entries that are something like this: "exr/cryptomatte/0/". If you are rendering all three AOV's (crypto_asset/object/material) to the same exr file, then you will hopefully see metadata entries for each one of those (the first one will be exr/cryptomatte/0/, the next exr/cryptomatte/1/ and the last exr/cryptomatte/2/).  If you aren't able to see these entries, then something is definitely getting mixed up on the Soft side of things.

Sorry for the slow response (I'll probably not be very available for the next week)

Brian is correct, it sounds like the problem is on the 3d side. Do you have objects with AlSurface applied renderable in your scene? Are you sure the name of the aov is the same as it is on the alsurface shader's string port?

Cropping does not matter, and nothing should be deep.
