    「レンダーエレメントってどうやって使うの?」
    「利用してもたいした効果ないでしょ」
    「そもそも情報すくなくてやりかたわからない」

    そんなこと考え悩んでいる方に向けた記事になる

    今回ご紹介する内容は

    【Photoshop】レンダーエレメントでポストプロダクション【建築パース】
    読書さんへのメッセージ

    建築CGの分野ではレンダリング後のレタッチはとても重要である。
    3DCGの進歩によってその重要性は前より高くないが、いまだ簡単に効果を追加できるので重宝している。

    3DCGシーンにおける効果を、2Dソフトでも調整できるように画像化したものをレンダーエレメントと呼ぶ。
    レンダリングを行う前に必要なものを選ぶのだが、どれがどのような効果があるのか理解できてない方も少なくないだろう。

    この記事では、弊社で行うポストプロダクションの作業をもとに、必要と思われる要素をその効果と共に解説していく。
    是非理解して実践してみてほしい。

    1. Cinema4Dでの準備

    まずは3DCGソフトで書き出す情報を選ぶ必要がある。
    今回もCinema4D+CoronaRenderにて説明を行っていくが、環境が異なっても内容は大きく変わらないので参考にして頂きたい。


    1-1. マルチパスによる設定

    Coronaメニューより「Malti-Pass」を選択してウィンドウを表示。
    建築CG静止画のポストプロダクションには、上画像の5項目で十分と考える。それぞれどのような効果があるかは個々に説明していく。Cinema4D上で設定が必要な「AO」と「WireColor」について解説する。

    前回の記事で「LightMix」と「LightSelect」でライティングの方法を紹介した。
    照明の配置がシンプルであれば、<Active passes>で「Multi-Pass」選択で出てくる「Setup interactive LightMix」+「Generate」クリックで簡単にLightMixの設定が可能。


    1-2. アンビエンオクルージョン

    AO(アンビエントオクルージョン)の項目はデフォルトではないため、「Texmap」を利用して項目を作る必要がある。
    「Apply denoising」にチェック、「Map」には>corona>「AO」を選択。AOシェーダーの「Max distance」を300mm(任意)に設定。この数値が影となる長さを指定する箇所になるので、必要に応じて調整してみよう。


    1-3. ワイヤーカラーの作り方

    オブジェクトの選択範囲情報が欲しい時にワイヤーカラーを利用している。これはオブジェクトに割り当てられたカラーで表示を行っている状態だ。マテリアルやオブジェクトのID設定で選択範囲を作るのが一般的かもしれないが、設定し忘れが起こりやすく、2Dでの作業効率も考えるとこの方法がよりよいと考える。

    オブジェクトのカラーを割り当ては、あまり行わないと思うので解説をしておく。

    上部ビューメニューのオプションより、マテリアルの選択を外すと、ウィンドウでの表示がマテリアルでなくオブジェクトのカラーになる。デフォルトではブルーグレーの状態なので、グーローシェーディングでも上画像右のような表示になる。

    わかりやすいように床のオブジェクトに色をつけていく。
    オブジェクトレイヤーで床を選択し、属性パレットから、表示カラーを「自動」その下のカラーボックスで色を選ぶ。これで床オブジェクトにカラーが割り当てられる。表示カラーを「オン」にすると、ビューメニューのオプションでマテリアルが選択されている状態でもカラーで表示されてしまうので注意しよう。

    同様の対応を、選択範囲が欲しいオブジェクトすべてに行い、ワイヤーカラーを完成させる。


    2. Photoshopでレタッチ

    Cinema4Dでの設定を終え、マルチパス画像の保存を行いPhotoshopで開くと、書き出し設定を行ったレンダーエレメントがレイヤー別に表示される。それぞれの利用方法を解説していく。


    2-1. ワイヤーカラー/WireColor

    ワイヤーカラーは一番下のレイヤーに配置しておき、自動選択ツールを使って選択範囲を利用していく。
    チャンネルを利用しないので出戻りが少なく、何度も利用できるので効率がよい。


    2-2. カラールックアップ/LUT

    カラールックアップを使って色調補正を行う。
    「filmstock_50.3d」を60%で適用。左のカウンター部のコントラストが強調され暗くなってしまったので、適用を除外するためマスクを設置して調整。

    2-3. アンビエントオクルージョン/AO

    アンビエントオクルージョンは扱いに注意が必要である。
    レンダリング画像の上に、乗算やオーバーレイ等で直接ブレンドしてしまい汚れた雰囲気が出てしまってるパターンがよくある。

    それを避けるためには、レンダリング画像の上に、そのコピーとAOレイヤーのグループを作り「乗算」でブレンド。グループの中のAOレイヤーは「スクリーン」でブレンド。これを行うことで自然に近い雰囲気でAOをかけられる。カラールックアップの時同様に、濃すぎる箇所にはマスクで調整。全体では不透明度でバランスを見る。


    2-4. リフレクション/Reflect(反射)

    リフレクションは反射の情報が詰まったレイヤーで、レンダリングでは足りない反射をレタッチで追加していく。
    Reflectレイヤーを「スクリーン」でブレンドし、黒で塗りつぶしたマスクを設置して効果がない状態にしておく。

    反射の足りないところや、強調したい箇所を白・ブラシで塗っていく。その際WireColorを利用して、選択範囲を都度設けながら作業を行うと綺麗に反映される。


    2-4. リフラクション/Refract(屈折)

    リフラクション(屈折)も反射同様の対応を行う。屈折が起こるのは主にガラス部である。

    2-5. BLOOM&GLARE

    レンズエフェクトであるBLOOM&GLAREはマルチパスではなく、別画像として保存してから利用する。

    AOの時と同じように、レンダリング画像のコピーとBLOOM&GLAREのグループを作り今度はスクリーンでブレンド。BLOOM&GLAREレイヤーは「差の絶対値」を選択。これで強弱、マスクを利用すればオンオフを調整できるようになった。

    この方法を利用すると若干エフェクトの効果が弱まるため、BLOOM&GLAREの数値は強めにしてから画像を用意するのがコツだ。


    3. ビフォーアフター

    以上のレタッチを行った画像と今回のポストプロダクションでの対応前後の比較画像になる。
    Shadowsレイヤーは、影が強くでてしまった場合に緩和するために利用するが、今回は必要なかった。
    また前回記事で紹介したVFBでのライティング調整も、それぞれのレイヤーが書き出されているので同様な形で利用することができる。


    4. レンダーエレメントでポストプロダクションまとめ

    以上がレンダーエレメントでポストプロダクションの解説である。

    インテリアシーンの場合、劇的な変化は望めないが必要不可欠な作業工程ではある。
    3DCGでの手間とレンダリング時間を考えると、どうしてもレタッチに頼りがちになるところがある。しかしレンダリングのリアリティは、レタッチの作業量と反比例すると考える。

    ポストプロダクションでの作業は色調補正や効果の追加程度にしておき、3DCGで様々な対応ができるようになるのが、建築CG上達のコツだと思う。

Another issue is that just being a photographer entails not only trouble in catching award-winning photographs but also hardships in getting the best camera suited to your needs and most especially challenges in maintaining the caliber of your camera. That is very genuine and evident for those photography lovers that are straight into capturing this nature’s captivating scenes : the mountains, the actual forests, the particular wild and the seas. Going to these exciting places certainly requires a dslr camera that can live up to the wild’s severe environments.

    25. Thanks for finally talking about > 【Photoshop】レンダーエレメントでポストプロダクション【建築パース】 | < Loved it!

    26. I do love the manner in which you have framed this specific challenge plus it does indeed present me personally a lot of fodder for consideration. Nonetheless, through what precisely I have observed, I just simply hope when other feed-back pile on that men and women continue to be on issue and don’t embark upon a soap box regarding some other news du jour. Yet, thank you for this excellent point and though I do not concur with the idea in totality, I respect your perspective.

    27. Just about all of what you say is astonishingly precise and that makes me wonder why I hadn’t looked at this in this light previously. This particular article really did switch the light on for me as far as this particular subject matter goes. But there is just one position I am not too cozy with so whilst I make an effort to reconcile that with the actual core idea of the point, permit me see exactly what the rest of your visitors have to point out.Very well done.

    28. Thanks for your write-up. One other thing is the fact individual American states have their own personal laws that affect people, which makes it quite hard for the our lawmakers to come up with the latest set of recommendations concerning foreclosed on homeowners. The problem is that every state features own regulations which may work in an adverse manner in relation to foreclosure procedures.

    29. fantastic post, very informative. I wonder why the other specialists of this sector do not notice this. You must continue your writing. I am confident, you’ve a great readers’ base already!

    31. very good post, i actually love this web site, keep on it

    32. Can I just say what a relief to search out someone who really is aware of what theyre speaking about on the internet. You definitely know tips on how to bring an issue to gentle and make it important. Extra people need to learn this and perceive this aspect of the story. I cant consider youre no more fashionable because you positively have the gift.

    33. One thing I have actually noticed is the fact that there are plenty of misconceptions regarding the banking institutions intentions when talking about property foreclosures. One delusion in particular is the bank desires your house. The lending company wants your hard earned dollars, not your house. They want the amount of money they loaned you together with interest. Steering clear of the bank is only going to draw a new foreclosed final result. Thanks for your write-up.

    34. One thing I’d prefer to say is that often before getting more computer system memory, check out the machine in to which it would be installed. If the machine is actually running Windows XP, for instance, the actual memory limit is 3.25GB. Applying greater than this would just constitute a new waste. Make sure one’s mother board can handle the upgrade volume, as well. Great blog post.

    35. Thanks for your beneficial post. Over time, I have come to be able to understand that the particular symptoms of mesothelioma are caused by a build up of fluid between the lining of the lung and the chest cavity. The ailment may start from the chest spot and get distributed to other parts of the body. Other symptoms of pleural mesothelioma include weight reduction, severe deep breathing trouble, fever, difficulty taking in food, and infection of the face and neck areas. It must be noted that some people with the disease do not experience any kind of serious symptoms at all.

    38. I really like looking through an article that can make men and women think. Also, many thanks for permitting me to comment.

    39. Interesting article. It is very unfortunate that over the last several years, the travel industry has already been able to to fight terrorism, SARS, tsunamis, flu virus, swine flu, as well as the first ever entire global economic downturn. Through all this the industry has proven to be strong, resilient along with dynamic, locating new tips on how to deal with misfortune. There are continually fresh problems and possibilities to which the sector must all over again adapt and answer.

    40. Oh my goodness! Impressive article dude! Thank you, However I am going through difficulties with your RSS. I don’t understand the reason why I cannot join it. Is there anyone else getting identical RSS issues? Anyone who knows the solution can you kindly respond? Thanx!!

    42. I know of the fact that now, more and more people are being attracted to video cameras and the industry of images. However, as a photographer, it’s important to first shell out so much time period deciding the model of digital camera to buy and moving store to store just so you could buy the cheapest camera of the brand you have decided to pick out. But it won’t end right now there. You also have to contemplate whether you should buy a digital digital camera extended warranty. Thanks a lot for the good recommendations I gathered from your weblog.

    43. Hey there, You have done an excellent job. I?ll certainly digg it and personally recommend to my friends. I am sure they will be benefited from this web site.

    45. I think other website proprietors should take this website as an model, very clean and magnificent user friendly style and design, let alone the content. You are an expert in this topic!

    46. It’s my opinion that a foreclosures can have a important effect on the debtor’s life. Mortgage foreclosures can have a Seven to several years negative relation to a client’s credit report. The borrower having applied for a mortgage or just about any loans for that matter, knows that the actual worse credit rating is usually, the more complicated it is for any decent loan. In addition, it may possibly affect any borrower’s capacity to find a good place to let or hire, if that will become the alternative property solution. Interesting blog post.

    47. That is the fitting blog for anybody who needs to find out about this topic. You realize so much its nearly arduous to argue with you (not that I actually would need?HaHa). You positively put a brand new spin on a subject thats been written about for years. Nice stuff, simply nice!

    52. WONDERFUL Post.thanks for share..extra wait .. ?

    53. Greetings! Very helpful advice in this particular post! It’s the little changes that produce the greatest changes. Thanks for sharing!

    54. I found your blog web site on google and check a number of of your early posts. Proceed to maintain up the superb operate. I just further up your RSS feed to my MSN News Reader. Looking for ahead to studying extra from you afterward!?

    55. Hello, I think your blog might be having browser compatibility issues. Whenever I take a look at your website in Safari, it looks fine however, when opening in IE, it’s got some overlapping issues. I just wanted to provide you with a quick heads up! Apart from that, wonderful site!

    56. I’ve learned quite a few important things through your post. I would also like to say that there will be a situation in which you will apply for a loan and do not need a cosigner such as a National Student Aid Loan. However, if you are getting credit through a regular finance company then you need to be ready to have a cosigner ready to help you. The lenders are going to base that decision over a few factors but the largest will be your credit score. There are some lenders that will also look at your work history and make a decision based on that but in many instances it will be based on on your rating.

    57. Hello, There’s no doubt that your website might be having browser compatibility problems. When I look at your website in Safari, it looks fine however, if opening in Internet Explorer, it has some overlapping issues. I simply wanted to provide you with a quick heads up! Besides that, great blog!

    58. I also believe that mesothelioma is a extraordinary form of cancer malignancy that is commonly found in those people previously exposed to asbestos. Cancerous tissue form inside the mesothelium, which is a defensive lining that covers a lot of the body’s internal organs. These cells ordinarily form from the lining in the lungs, stomach, or the sac that encircles the heart. Thanks for discussing your ideas.

    59. Thanks for the recommendations shared on your blog. Something also important I would like to talk about is that weight loss is not all about going on a dietary fads and trying to get rid of as much weight as possible in a few days. The most effective way to lose weight naturally is by getting it gradually and following some basic ideas which can enable you to make the most through your attempt to lose weight. You may recognize and be following these tips, although reinforcing know-how never hurts.

    60. I’m impressed, I have to admit. Rarely do I come across a blog that’s equally educative and engaging, and without a doubt, you’ve hit the nail on the head. The problem is an issue that not enough men and women are speaking intelligently about. Now i’m very happy I stumbled across this during my hunt for something regarding this.

    61. I would like to thank you for the efforts you’ve put in writing this site. I’m hoping the same high-grade website post from you in the upcoming also. In fact your creative writing skills has inspired me to get my own web site now. Really the blogging is spreading its wings fast. Your write up is a great example of it.

    62. I blog frequently and I really appreciate your information. The article has really peaked my interest. I will book mark your blog and keep checking for new details about once per week. I subscribed to your Feed too.

    63. One more thing. In my opinion that there are quite a few travel insurance internet sites of reliable companies that allow you enter your journey details and obtain you the insurance quotes. You can also purchase the international travel insurance policy on the net by using the credit card. All that you should do is usually to enter your travel details and you can be aware of the plans side-by-side. Just find the package that suits your financial allowance and needs and after that use your credit card to buy it. Travel insurance on the internet is a good way to check for a trustworthy company pertaining to international holiday insurance. Thanks for revealing your ideas.

    64. Thanks alot : ) for your post. I would like to comment that the cost of car insurance differs a lot from one insurance policy to another, due to the fact there are so many different issues which give rise to the overall cost. By way of example, the brand name of the vehicle will have an enormous bearing on the fee. A reliable old family vehicle will have a less expensive premium than the usual flashy fancy car.

    65. Thanks for the recommendations you have discussed here. Something important I would like to state is that laptop or computer memory requirements generally rise along with other developments in the technological know-how. For instance, whenever new generations of processor chips are introduced to the market, there’s usually a matching increase in the dimensions demands of all laptop memory and also hard drive room. This is because software program operated by these cpus will inevitably surge in power to make new know-how.

    66. Today, taking into consideration the fast way of life that everyone leads, credit cards have a big demand throughout the market. Persons throughout every arena are using credit card and people who aren’t using the card have made arrangements to apply for even one. Thanks for spreading your ideas on credit cards.
