Do you mean normal map? I think I had posted this before, but since I'm getting old and my memory gets worst, so here you go.

我都記得好耐之前睇過國內 maya 前輩 - 張軍既文章, 佢都有解釋過 normal mapping, 仲系中文添..... 不過搵唔番 lor (又系年紀大唔記得)


如果你真系問 normal pass 同後期既野呢...... 我可以話你知, 真正 production 好少用. 因為 normal pass 去到後期可以 get 到畫面 objects 既 coordinate, 有個大概空間關系, d人就會用呢d information 去做 re-lighting, 姐系 comp 做 lighting.

comp 做 lighting 好處就系快, 壞處就系唔夠 details, cast 唔到 self shadow. 而且 production 入面有 lighting artists, 有料既 lighting artists 會喺 3d 打准哂d 光源位置, 顏色既關系 bounce & fill color 都會做埋, comp 只系 color & contrast 上再幫下手. 如果要 comp 執埋 lighting 方向, 勾 shadow, 一來做死 comp 既人, 二來即系 lighting artist 冇料到
