    Hi Renato,

    Please ask your questions in a way I can follow you. What is it you want to achieve? From your last reply I was assuming the problem has been resolved. We both are not native English spekaers so please try to word your questions are bit more clearly.

    cheers,
    Matthias

    Hello Matthias,

    what i need is get all vpbuffer in the best way.
    I'm getting now the basic vpbuffer from render.. but seem that is better to get all them from Multipass..

    Any suggestions?

    Cheers
    Renato

    I am not sure but could you not get all the information from the Multipass structure found in the PixelPost structure?

    Do you need the passes after or during rendering?

    i need to find all the VPBuffer opened by multipass. So i can fire pixels from vray to them :)
    So i need them in Execute..

    Here's how to browse through a multipass bitmap. For lights there is an inner loop that retrieves the data.

    The main bitmap should be checked with bmp->IsMultipassBitmap() first and then casted into a (MultipassBitmap* )

      
         LONG j,i,id;  
         LONG cnt = b3d->GetLayerCount();  
      
         for (i=0; i<cnt; i++)

              MultipassBitmap *sublayer,*layer = b3d->GetLayerNum(i);  
              if (!layer) continue;

    Thanks Philip,

    but what do you mean about main bitmap?

    do i need to get it from Multipass::VPBitmap[0]?

    You can retrieve the main bitmap by calling

      
    MultipassBitmap *mpb = (MultipassBitmap* )renderinstance->GetBuffer(NOTOK,0);

    Hello Philip,

    where:
    LONG subcnt = layer->GetLayerCount();

    subcnt always is -1 so the internal cycle go in loop forewer.

    What's mean that GetLayerCount() return -1 ?

    cheers

    But Philip did this in his loop:

    for (j=0;j<subcnt || subcnt==-1;j++)
    

    Probably explicitly to avoid the infinite loop. No idea about what -1 represents here though.

    Are you sure of your types (LONG)? In actuality, all that is needed is:

    for (j = 0; j < subcnt; ++j)
    

    Since -1L is less than 0L, the loop should exit immediately. But if ULONG is used, -1L is of course 4 billion.

    All else failing, just check for -1 on subcnt and avoid the loop altogether:

    LONG subcnt = layer->GetLayerCount();  
    if (subcnt < 0)     continue;  
    for (j=0; j!=subcnt; ++j)  
    ...
