Thread: ids and semantics in a Collada file describing a morph

    ids and semantics in a Collada file describing a morph

    I have exported a scene from Maya which has an animating face (created with blendShape and multiple targets).

    In the output file there are ids of the form:


    Is this a valid id? The (1) is used as part of the id name and not part of a reference to an <array> element.

    I understand that weight-array(1) is valid if weight-array is the id of an <array> type node, with (1) indicating the index of the element in the array.

    Secondly the file contains param's with no name value:

    Code :
    <param name="" type="float" flow="OUT"/>

    Is this invalid?

    "Face-lib-weights(1)-animation-input" is in fact not a valid id. And an empty string in the <param>'s name attribute is also invalid. The validation tests that we ran last week wasn't happy about these two .

    I fixed this on Moday, though. Can you try the latest build that was released on Tuesday, please?

    Also, while on the subject of blend shapes and conformance: there was no fully conformant way to express blend shapes in Collada. If you have any ideas on how to improve it, from your experience, I'm all ears!
