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..Cheers

Hi all,
Here the scene that i've examined:
i wrote this piece of code looking for the separate light pass:

Thanks all

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(); } } -

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.

Hello dear Robert,
but when the subcnt == -1.. it loop

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?

To retrieve the alpha channels use:

Ah.. thanks.. i forgot that ObjectID are in fact alpha channels
Thanks a lot
