Cryptomatte and Deadline

[Dubbie99]

Hi,

I can't seem to get Cryptomatte to work when rendering my scene with Deadline.
When I render my scene in the VFB, the Cryptomatte shows a different ID for each packed object. This is what I want.
When I render with Deadline, it has the same ID (default) for all the objects.

I am using Node User Attribute in the Cryptomatte render channel. You can see a screenshot of my settings
I have a name string on my objects. You can see the spreadsheet attached.

I also have the attribute specified in "forced attributes" on the object node.
To cover my bases, I also have it forced in the render ROP.

The objects are generated with a copy to points node. The geometry is packed.

What am I missing here?

Houdini 18.0.460
vraystd_adv_43002_x64_vc14

It is preferred to use VfH as standalone when rendering on a farm, because it is highly possible fixes and features which are available in VfH nightly build to not been added to official standalone build yet.

I understand. I didn’t realise that there was a vRay for Houdini stand-alone mode.
does it consume workstation licenses though? Or can we use our normal render licenses to render?

Hey Dubbie99 ,

only a Render Node license is consumed when rendering VRScenes straight from the vray.exe - this holds true for all integrations. GUI licenses are only used when working inside a DCC application, e.g. Maya, Houdini, etc.

Best regards!

WIll the generic Max/Maya render licenses work to render VRay Houdini scenes? Or do we need to buy specific Houdini render licenses?

I think I've confused you...

So, you have two license types:
1. GUI (Graphical User Interface) licenses - you need those to open V-Ray in the application, use the materials, textures, tweak the render settings, and so on. For example, to use V-Ray for 3ds Max, you need a V-Ray GUI license for 3ds Max. To use V-Ray for Houdini, you need a V-Ray GUI license for Houdini.
2. To render with V-Ray, you need a V-Ray Render Node license. A Render Node license is always used when you hit render - it doesn't matter if you hit "Render" in 3ds Max, or Maya, or Houdini.

So, if you have Render Node licenses that came with Max/Maya - those will work perfectly fine with V-Ray for Houdini.

Does that answer your question ?

Best regards!

[Dubbie99]

Yes it does. Thanks!
I just know there was a time when render licenses weren't universal. I'm glad they are now.

Awesome, glad we figured it out
By the way, as of recently there are also universal GUI licenses, e.g. https://www.chaosgroup.com/vray/collection
May be worth looking into in case you jump a lot between DCCs.

Best regards!

Btw, there is no need to force attributes if the attribute name is used at Tex User Color/Float/Int, Tex TriPlanar (random by user attribute) and Cryptomatte (in user attribute mode) - those values are collected and forced automatically.
