    Looks like a variation of deep EXRs (limit number of samples, add object name table), should not be too difficult to add. I guess it will take very
    long until it is part of the OpenEXR specification.

    Pavel, the query function returns the leaf transform, i.e. all intermediate transforms multiplied. Are you looking for the
    transform just to the parent space of a specific light ? This would require...

    The texture vertex sharing looks odd in this scene. If you intend to put a checkerboard onto a cube and render it smoothly
    without visible seams/strange borders, all six faces of the cube must have...

    Hello,
    do you frequently use this "disable uv smooting" mode ? It usually results in all kinds of bad distortions when the surface is approximated with
    subdivision surface rules and the textures...

    Andreas, what kind of material is used in your scene (regular material, phenomenon ?). Could you perhaps show us a short fragment of
    the material definition (even better would be an example scene) ?...

    Hi Andreas,

    the surface shader is set in miMaterial::shader, so you could access it with the following code (it works for simple materials,
    not material phenomena)
    miMaterial * mtl =...

    Scott,
    this should be possible by setting the flags (visible etc) in the instance (i.e. transform node in Maya). They are inherited for all objects defined in the alembic archive.

    Deane, storing the opacity values as user data or texture sounds like a good idea if you need such fine control over opacity.

    Hello,
    it looks like your scene renders slower because of different settings in Maya 2016 compared with the previous version. In addition, it appears that light importance sampling (enabled by...

    Hi,
    there is no size limit on the assembly files. It looks more like a shader getting wrong parameters and doing berzerk memory
    allocations. Do you perhaps have more details ? We could take a look...

    The differentials are enabled by setting the string option "ray differentials" to true. The default is off, however from Maya it is set to true (at least in 2014).
