Re: Using AEGP_StartUndoGroup / EndUndo to force an asynchronous re-render

Finally I managed to do it using Idle ,yes it works with Effects plug-ins!

Just as documentation for future readers:

AEGP_EffectRefH meH;

AEGP_StreamRefH streamH ;

suites.PFInterfaceSuite1()->AEGP_GetNewEffectForEffect(pluginID, mEffectRef, &meH);

if(meH)

{

   (suites.StreamSuite2()->AEGP_GetNewEffectStreamByIndex(pluginID, meH, SLIDER_DISK_ID, &streamH));

   if (streamH)

    {

       ERR(suites.DynamicStreamSuite2()->AEGP_SetDynamicStreamFlag(streamH, AEGP_DynStreamFlag_HIDDEN, TRUE, TRUE));

       ERR(suites.StreamSuite2()->AEGP_SetStreamValue(pluginID,streamH,&val));

       ERR(suites.StreamSuite2()->AEGP_DisposeStream(streamH));

   }

   ERR(suites.EffectSuite2()->AEGP_DisposeEffect(meH));

}

In fact the only thing I didn't manage to do was PF_PUI_NO_ECW_UI since I wanna make a hidden slider that is change on Idle to force re-render, on that iddle I can hide it using

ERR(suites.DynamicStreamSuite2()->AEGP_SetDynamicStreamFlag(streamH, AEGP_DynStreamFlag_HIDDEN, TRUE, TRUE));

But if the idle hook is not called it is visible

Let's continue exploring AE SDK!

Thank you so much for your help shachar!
