silhouette alpha

    Hi.
    Little problem:
    i'd like to display jit.gl.text2D behind a silhouette (from jit.qt.grab).
    So i make a alpha mask wich i want to control with my silhouette (jit.alphablend).
    But the layer is still black………
    Here's my png mask, and my patch:
    max v2;

      i think you need to use @blend_mode 6 1 on your videoplane, although i'm not entirely sure why the default mode of 6 7 is not working.

      I've made several tests and still the same problem:
      The alpha channel from png is not reconize with jit.alphablend !!
      10.5 Max 4.6 and Max 5.

      I don't think jit.alphablend does what you think it does. It's purpose is to blend 2 inputs together based on an alpha channel, and will essentially strip off any alpha information on output. Try removing it from the patch and connecting directly from the jit.pack to jit.gl.videoplane.
