Hi,

I would like to add Post Effects under Multi-Pass using the code:

 
					rd->SetParameter(RDATA_MULTIPASS_ENABLE, 1, DESCFLAGS_SET_0); // Enable the multi pass option
  
					MultipassObject *mpo = NULL;
					mpo = (MultipassObject* )MultipassObject::Alloc(Zmultipass);
					if (mpo)
					{
						BaseContainer *mdata = mpo->GetDataInstance();
						mdata->SetInt32(MULTIPASSOBJECT_TYPE, VPBUFFER_POSTEFFECT);
  
					//	GeData data;
					//	data.SetInt32(VPBUFFER_POSTEFFECT);
					//	mpo->SetParameter(DescID(MULTIPASSOBJECT_TYPE), data, DESCFLAGS_SET_0);
  
						doc->StartUndo();
  
						rd->InsertMultipass(mpo, NULL);
  
						doc->AddUndo(UNDOTYPE_NEW, mpo);
						doc->EndUndo();
  
						rd->Message(MSG_UPDATE);
						EventAdd();
					}

But it adds only an empty line under Multi-Pass. Even using currently commented SetParameter doesn't help.
How to add it programmably?

My example is based on https://developers.maxon.net/forum/topic/5716/5761_multipassobject-allocation&KW=MULTIPASSOBJECT_TYPE&PID=24000#24000 which works well for RGBA, but I need Post Effects too! Please, help.

Hi,

you are using the wrong MULTIPASSOBJECT_TYPE. Instead of VPBUFFER_POSTEFFECT (which is used with AllocateBuffers()) you need to use VPBUFFER_ALLPOSTEFFECTS. There is no option to add a MultipassObject just for one single specific VideoPost.
Some more information can be found in the MultipassObject manual.

Hi Andreas, thanks a lot, will try it just now!

Btw, I have noticed that when Multi-pass is enabled by user or programmably then C4D applies pow(pix, 1.0f/2.2) to all the single layers and results of operations on layers. And this doesn't happend when Multi-pass is disabled (i.e. single image). Btw, does Cinema use 2.2 or pricise srgb curve? If uses 2.2 then can user change it in the settings?
