Hi,

I am trying to allocate a depth buffer when the MSG_MULTI_RENDERNOTIFICATION message is sent to my object:

RenderNotificationData* rnd = (RenderNotificationData* )t_data;  
if(rnd->external && rnd->start)  
  if(!rnd->render->AllocateBuffer(VPBUFFER_DEPTH,0,8,TRUE))  
  GePrint("not Allocated");  
 

However, I don't get the according channel shown in the Picture viewer (AllocateBuffer returns TRUE btw). What am I doing wrong here or am I expecting the wrong thing?

Thanks in advance

It seems that allocation of multipass buffers is only possible in a videopost. I will ask the developers to make sure.

cheers,
