Add Self Publish Button​

Setting Location: ayon+settings://houdini/general/add_self_publish_button

Enabling this setting will cause Houdini creator to add a self publish button when creating new publish instances. More Info on how how the self publish button works here.

Update Houdini Vars on context change​

Setting Location: ayon+settings://houdini/general/update_houdini_var_context

Allows admins to have a list of vars (e.g. JOB) with (dynamic) values that will be updated on context changes, e.g. when switching to another asset or task.

1. Update Houdini vars on context change : Disabling this setting will leave all Houdini vars unmanaged and thus no context update changes will occur.

2. (+) : add new Houdini variable

3. Var : The Houdini variable you want to add. No need to include $.

   For consistency reasons we always force all vars to be uppercase. e.g. myvar will be MYVAR

4. Value : The value you want Ayon to maintain.

   You can use these tesmplate keys.
   Refer to FAQ below to learn about the subpported keys.

5. Treat as directory : If activated, Ayon will consider the given value as a path of a folder.

   If the folder does not exist on the context change it will be created by this feature so that the path will always try to point to an existing folder.

Color Management (ImageIO)​

Workfile

Workfile colormanagement settings. When enabled, it sets default view and default display for houdini via setting OCIO_ACTIVE_DISPLAYS and OCIO_ACTIVE_VIEWS env vars on application launch.

• Default active displays: Like the OCIO_ACTIVE_DISPLAYS env var, uses Colon-separated list of displays, e.g ACES:P3

• Default active views: Like the OCIO_ACTIVE_VIEWS env var, uses Colon-separated list of views, e.g sRGB:DCDM

• Review colorspace: It represents OCIO Colorspace parameter in opengl nodes. if left empty, Ayon will figure out the default colorspace using your default display and default view.

Shelves Manager​

Setting Location: ayon+settings://houdini/shelves

Allows admins to add studio's Shelves and scripts into Houdini.

Setting Modes​

Shelves manager works in two modes, it's either option 1 or 2.

1. Add a .shelf file by only setting the Shelf Set Name and Shelf Set Path.

   

2. OR set the Shelf Set Name and create shelf definitions with shelf scripts dynamically.

   Currently, Ayon just adds the new shelf definition in default.shelf

   

Shelves Example​

In this example I made two shelves:

1. Null Shelf which gets loaded from my pre-defined null_shelf.shelf file.

2. Ayon Shelf which includes my script Say Hello.

Creator plugins​

Setitng Location: ayon+settings://houdini/create

Enable or disable the plugins. Some of them have extra options such as defining the default products names.

Enable or disable the plugins executed at publishing.

Collect Asset Handles​

Setting Location: ayon+settings://houdini/publish/CollectAssetHandles

Validate Instance in same Context​

Setting Location: ayon+settings://houdini/publish/ValidateInstanceInContextHoudini

When working in per-shot style you always publish data in context of current asset (shot). This validator checks if this is so. It is optional so it can be disabled when needed.

FAQ​

How to add my menus, tools and digital assets to Houdini ?​

You can add them via adding custom shelve using Shelves Manager as you can easily use them to share a lot of tools with your team.

Alternatively, you can use environment variables e.g.,

• PYTHONPATH to add a custom python library path

• HOUDINI_MENU_PATH to add a custom menu path

• HOUDINI_OTL_PATH to add a custom digital assets path

Ayon allows you to add environment variables as:

1. Global environment variable (it will be available for all DCCs)

2. Application specific (it will be available for a particular DCC)

3. Application variant specific (it will be available for a particular DCC version)

4. Tool (it will be available on demand per DCC per project per asset)
