    Hi! Is it possible to update the Picture Viewer while rendering? I'm rendering into a VPBuffer from a
    VideoPost plugin. Currently it only updates the Picture Viewer when it goes on to the next frame or
    when I force it to by dragging along the timeline or dragging the picture around.

    Thanks in advance!

    changes to the VPBuffer should be visible in the Picture Viewer window. This example updates just fine while "rendering". But it seems the Picture Viewer only updates a few times per second.

    VPBuffer* colorBuf = vps->render->GetBuffer(VPBUFFER_RGBA, NOTOK);  
    Int32 const xres = colorBuf->GetInfo(VPGETINFO_XRESOLUTION);  
    Int32 const yres = colorBuf->GetInfo(VPGETINFO_YRESOLUTION);  
    Random rnd;  
    for (Int32 y = 0; y < yres; ++y)  
      for (Int32 x = 0; x < xres; ++x)  
      this->SetPixelBuffer(x, y, Vector(rnd.Get01(), rnd.Get01(), rnd.Get01()), colorBuf);  
      if (vps->thread->TestBreak())  

    The SetPixelBuffer () utility function simply sets the given VPBuffer using GetLine()/SetLine(). Do you do something different?

    Best wishes,
