Function Documentation

HAPI_DECL HAPI_GetPreset	(	const HAPI_Session *	session,
		HAPI_NodeId	node_id,
		char *	buffer,
		int	buffer_length
	)

Generates a preset for the given asset.

Parameters

[in]	session	The session of Houdini you are interacting with. See Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The exposed node id.
[out]	buffer	Buffer to hold the preset data.
[in]	buffer_length	Size of the buffer. Should be the same as the length returned by HAPI_GetPresetBufLength().

HAPI_DECL HAPI_GetPresetBufLength	(	const HAPI_Session *	session,
		HAPI_NodeId	node_id,
		HAPI_PresetType	preset_type,
		const char *	preset_name,
		int *	buffer_length
	)

Generate a preset blob of the current state of all the parameter values, cache it, and return its size in bytes.

Parameters

[in]	session	The session of Houdini you are interacting with. See Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The exposed node id.
[in]	preset_type	The preset type.
[in]	preset_name	Optional. This is only used if the preset_type is HAPI_PRESETTYPE_IDX. If NULL is given, the preset name will be the same as the name of the node with the given node_id.
[out]	buffer_length	Size of the buffer.

HAPI_DECL HAPI_SetPreset	(	const HAPI_Session *	session,
		HAPI_NodeId	node_id,
		HAPI_PresetType	preset_type,
		const char *	preset_name,
		const char *	buffer,
		int	buffer_length
	)

Sets a particular asset to a given preset.

Parameters

[in]	session	The session of Houdini you are interacting with. See Sessions for more on sessions. Pass NULL to just use the default in-process session.
[in]	node_id	The exposed node id.
[in]	preset_type	The preset type.
[in]	preset_name	Optional. This is only used if the preset_type is HAPI_PRESETTYPE_IDX. If NULL is give, the first preset in the IDX file will be chosen.
[in]	buffer	Buffer to hold the preset data.
[in]	buffer_length	Size of the buffer.
