#SDS Strangeness - Macromedia Director 3D

Greetings experts. Has anybody had trouble with #SDS moifier in OpenGL and DX5 render modes? I have a weight mapped boned character that I apply the #SDS modifier to. In DX7 and software modes the model looks perfect. However in OpenGL and DX5 the model flickers like the sds is turning on and off every other frame, and the shininess of the hilights seems to flicker between overly bright and normal, giving the object an over shiny flicker. What's interesting is that the flicker ONLY happens when the camera moves or rotates with the 3D world. Anyone else found this ...

    Default #SDS Strangeness

    Greetings experts.

    Has anybody had trouble with #SDS moifier in OpenGL and DX5 render modes?

    I have a weight mapped boned character that I apply the #SDS modifier to. In
    DX7 and software modes the model looks perfect.

    However in OpenGL and DX5 the model flickers like the sds is turning on and
    off every other frame, and the shininess of the hilights seems to flicker
    between overly bright and normal, giving the object an over shiny flicker.

    What's interesting is that the flicker ONLY happens when the camera moves or
    rotates with the 3D world.

    Anyone else found this or have any workarounds?

    Thanks

    Richard

    Hi Richard,
    The strange part is that on certain machines (Vcards & drivers) you'll get the
    right result on OpenGL and the wrong one on DX7 and DX9.
    Here is another example: http://necromanthus.com/docs/OpenGL_vs_DirectX9.html
    Obviously this is a SW 11 Player bug (shaders & global lighting related).
    Let's hope they're going to fix it as soon as possible.

    cheers

    OK, not just me being stupid then ;)

    It the flickering happens on #sds models for me though. Does the DX9 issue
    you linked to happen on normal non #sds objects too?

    Thanks for the info Necro!

    It happens on DX7 and DX9, SDS and non-SDS both.
    Statistically speaking, in Shockwave 3D you'll get better visual results on
    OpenGL.

    cheers
