Photoshop smudge tool pack & performance tips / PS塗抹工具包

Recently I posted some process photos and mentioned I'm using smudge tools. Actually I smudging on all of my paintings in Photoshop. But first thing you need to understand is that in Photoshop, smudge tool is not optimized for making 'flat-style' paintings. (for example: anime style) It's for 'turning strokes to surfaces'. This idea is basically inspired by traditional painting/drawing, like charcoal or oil painting.

I make one smudge tool pack as an attachment in this post. This pack have both .abr and .tpl format, if you're using cc2018, load the .abr file; if you're using older versions, load the .tpl file.

My PC doesn't lag much in Photoshop, but I know there're some ways to improve the performance of smudge tool, if you're running on a low-end PC/graphic card:

• Don't use too dense brushes, uncheck 'spacing' in Brush Settings, or make spacing very big.
• Uncheck 'samples cloned data from composited data' ( in older versions it's 'samples all layers' ), or just paint on less layers. 
• If these doesn't help much, then you may need to improve the overall performance of PS, see the descriptions in this image below:

Also there's a great tutorial on youtube made by artist Borodante, who offers more ways to improve PS performance. See the video: MAKING PHOTOSHOP PAINTING FAST - Tutorial

最近貼了幾個繪圖過程截圖，提到我每張圖都使用了塗抹工具。基本上用PS畫圖我完全離不開塗抹工具，會來回在塗抹和筆刷工具間切換來切換去(還特地跑去改熱鍵)，話說PS的塗抹工具和日系軟體不同，基本不容易塗得平整，但對大部份的厚塗技法來說、塗得平不平整完全不是重點。使用PS的塗抹工具，基本上要先有個概念：「塗抹是為了將筆觸轉換為塊面」，這類技法基本上是源自於傳統媒材的素描/混色技法，比方說炭筆畫或油畫等。

如果對例圖中的塗抹工具有興趣，可以在本帖的附件下載這些塗抹工具。CC2018使用者請載入.abr格式，若安裝的是較舊版本，請載入.tpl格式。

有些贊助者似乎有在PS中使用塗抹工具會LAG的問題，雖說我的電腦基本不太會LAG所以無從測試起，但還是分享一下我目前知道的改善方法：

• 不要使用太綿密的筆刷。在筆刷設定欄中將"間距"取消掉、或者把間距值調得越大越好。
• 取消核選"從複合資料中仿製樣本資料"(在其他版本可能叫別的名字，總之核選方塊位置應該一樣)，或是盡量減少圖層數量
• 假如以上方法不奏效，那恐怕得對整個PS效能做調整，調整方式如下圖：

其實我之前在噗浪上就貼過，Youtube上有個很不錯的教學，影片製作人為烏克蘭繪師Borodante。影片提供更多種改善PS效能的設定方法：MAKING PHOTOSHOP PAINTING FAST - Tutorial
不過是英文教學，需要翻譯的話可以提出來，雖然我不見得有空幫忙翻(欸)
