                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;  
                  
                          LONG subcnt = layer->GetLayerCount();  
                  
                          for (j=0;j<subcnt || subcnt==-1;j++)  
                          {  
                               if (subcnt>0)  
                                    sublayer   = layer->GetLayerNum(j);  
                               else   
                                    sublayer = layer;  
                  
                               if (!sublayer) continue;  
                  
                               id = sublayer->GetParameter(MPB_USERID).GetLong();  
                          }  
                     }

                  but what do you mean about main bitmap?

                  do i need to get it from Multipass::VPBitmap[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)  
                            ...

                                Hello Philip,

                                ok now 🙂 but the objectID are the only buffers not detected with this way 😞

                                any suggestions?

                                Cheers
                                Renato

                                  To retrieve the alpha channels use:

                                    
                                  cnt = b3d->GetAlphaLayerCount();  
                                  for (i=0; i<cnt; i++)  
                                  {  
                                       B3dBitmap *layer = b3d->GetAlphaLayerNum(i);  
                                       if (!layer) continue;  
                                    
                                       id = sublayer->GetParameter(MPB_USERID).GetLong();  
                                       if (!id) continue;  
                                    
                                       ...  
                                  }
