I want to render the object and display the progress with model. but I have an little problem that can't implement display the progress. since I am an newcome student about c4d, how can I to modify the code section :
AddUserArea( PREVIEW_AREA_ID, 0, m_bmp->GetBw(), m_bmp->GetBh());
AttachImage(PREVIEW_AREA_ID, m_bmp, 0);
this is my all code modifly after :
#ifndef __RENDER__COMMON__H
#define __RENDER__COMMON__H
#include "c4d.h"
#include "c4d_symbols.h"
#include "c4d_general.h"
#include "c4d_baseobject.h"
