Visibility bitmask values

[alan-LFL]

Hi all,

Sorry to ask this incredibly stupid question, but I'm clearly grepping the wrong thing.

In the user docs there are details for the visibility flags https://docs.arnoldrenderer.com/display/A5AFMUG/Visibility

But when I search the API docs, headers, Arnoldpedia etc, I can't find anything giving me a hint at either constants in the headers or specific values for me to use to set the visibility attribute on an AtNode.

Could somebody point me to the docs/header I'm failing to find?

Cheers,

Alan.

Awesome, that's exactly what I needed, thank you.

In ai_ray.h:

/** \name Ray Types
 * \{
 */
#define AI_RAY_UNDEFINED         0x00  /**< undefined type                      */
#define AI_RAY_CAMERA            0x01  /**< ray originating at the camera       */
#define AI_RAY_SHADOW            0x02  /**< shadow ray towards a light source   */
#define AI_RAY_DIFFUSE_TRANSMIT  0x04  /**< indirect diffuse transmission ray   */
#define AI_RAY_SPECULAR_TRANSMIT 0x08  /**< indirect specular transmission ray  */
#define AI_RAY_VOLUME            0x10  /**< indirect volume scattering ray      */
#define AI_RAY_DIFFUSE_REFLECT   0x20  /**< indirect diffuse reflection ray     */
#define AI_RAY_SPECULAR_REFLECT  0x40  /**< indirect specular reflection ray    */
#define AI_RAY_SUBSURFACE        0x80  /**< subsurface scattering probe ray     */

Ahhh, this explains why grepping visibility didn't help 🙂 even better, thanks.
