Hey Everyone,
How can one go about inserting a new Multipass layer (i.e VPBUFFER_OBJECTBUFFER) into the RenderData? The RenderData has a method InsertMultipass which takes a MultipassObject*, but the MultipassObject has no allocation methods. So essentially I am asking how can I allocate a MultipassObject*.

I've tried using BaseList2D::Alloc(VPBUFFER_OBJECTBUFFER) and casting the resulting pointer to a MultipassObject to no avail.

Thanks in advance,
Josh

A multipass is allocted and inserted like this:

  
RenderData *rd = doc->GetActiveRenderData();  
  
MultipassObject *mpo = NULL;  
mpo = (MultipassObject* )MultipassObject::Alloc(Zmultipass);  
if (!mpo) return FALSE;  
  
BaseContainer *data = mpo->GetDataInstance();  
data->SetLong(MULTIPASSOBJECT_TYPE, VPBUFFER_RGBA);  
  
doc->StartUndo();  
  
rd->InsertMultipass(mpo, NULL);  
  
doc->AddUndo(UNDOTYPE_NEW, mpo);  
doc->EndUndo();  
  
rd->Message(MSG_UPDATE);  
EventAdd();

I will include this into the docs.

cheers,
Matthias

Mattias,

Could you please consider adding this line of code in your docs example as well:

rd->SetParameter(RDATA_MULTIPASS_ENABLE, 1, DESCFLAGS_SET_0); // Enable the multi pass option

That way people reading that SDK will also know how to enable it too.

Just a friendly suggestion ,
