| Post subject: | How to Ignore Node and Children in Cast Ray |
Hi I have a use case where I would like to cast rays several times a second near avatar and ignore the avatar node and its children. Is there a way to do this and if not would this be a candidate to the API. So you could also give node(s) to ignore in the ray cast? Regards, Tommi |

You could try setting different parent nodes for the avatar and the other parts of the scene. |

Or just iterate over the results and check if the node to ignore is in the list of parents of the intersection node. |

Hi Thank you for the replies. I am currently doing the latter: Manually iterating the parents but that results some unnecessary processing I would like to optimize out. The different parent node might be a working solution in this specific case all though it is sub optimal as generic solution because it makes the scene graph more complex. -tommi |

This would be solved with the node flags that I have in mind. Each node would get a specific set of optional flags like invisible, noCastShadow and also noRayQuery. |
