Hi All,

there is a way to get the array of VPBuffer if i set the render of each light and the array of the VPBuffer for all objects ID when i set multipass rendering?

Here some code:

LONG buffercount = 11;
VPBuffer **myVpBuffers = (VPBuffer** ) GeAlloc (buffercount * sizeof(VPBuffer* ));
for (LONG iBuf = VPBUFFER_RGBA; iBuf < VPBUFFER_ATMOSPHERE_MUL; iBuf++) {
     myVpBuffers[iBuf] = render->GetBuffer(iBuf,0);
}

so myVpBufferrs _will be null if corrispondent multipass is not set.

But will be good to get the pointer to the lights and Id :)

thanks in advance
Renato

sorry, I can't quite follow you here. you only get a shdow, diffuse and specular pass for each light and an alpha pass for each object id. do you want access to these passes?

cheers,

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?

cheers,

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..

gefree etc.etc.etc..  
  
  

Now..why all others lights layers are not in the list?

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);

               if (!sublayer) 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);
