【AI繪畫】極樂disco,生成油畫風你需要知道的一切

2023-04-13 22:07 作者:向內(nèi)生長_  | 我要投稿

這次測試的是極樂disco風格的lora模型。

極樂disco是一款來自愛沙尼亞(現(xiàn)總部英國倫敦)ZA/UM游戲工作室的CRPG類游戲,以獨特的敘事風格,畫風與音樂著稱。當然,畢竟我們討論的主要是AI繪畫,所以無關(guān)繪畫的部分就不過多贅述。

關(guān)于極樂disco的畫風,它主要源自俄羅斯繪畫歷史上最偉大的畫派——巡回畫派,巡回畫派的基本主張是:堅持車爾尼雪夫斯基“美就是生活”的藝術(shù)思想,反對俄羅斯藝術(shù)上的西歐化,強調(diào)民族特點,以反映本國人民的生活與人民的苦難為自己的責任。

故而在極樂disco的美術(shù)風格中也貫徹了這一主張,提倡現(xiàn)實主義,畫面粗獷、筆觸奔放、色彩大膽。

先說結(jié)論

極樂disco大模型在畫面表現(xiàn)非常不錯,一些寫實風格ckpt大模型環(huán)境下甚至可能融合出意想不到的效果。但兼容性較差,若是想用它還原一些人物,需要小型的調(diào)整權(quán)重。在圖生圖的風格遷移方面表現(xiàn)令人驚喜,不過在提示詞方面需要注意寫的更詳細一些。

日常使用權(quán)重建議:0.8~1.0

人物生成權(quán)重建議:0.4~0.8

圖生圖風格遷移時,權(quán)重建議:0.8~1.25 ?重繪幅度建議:0.4~0.5

結(jié)論

圖中的橫軸為CKPT大模型,從A到E依次排列,縱軸為極樂disco lora的權(quán)重,從0.8到1.1。

在無論從人物還是場景,都可以看出,極樂disco lora的兼容能力。并且在一些情況下融合成了獨特的畫風。

A,E模型都是相對平面的畫風,在此環(huán)境下生成的作品則比較忠于原始畫風。

B,D模型則為相對立體的畫風,其中D為完全的真實照片風格,在此環(huán)境下則融合誕生出了一種更加強調(diào)色彩與線條的全新風格

結(jié)論

原神諾艾爾測試中,橫軸為人物lora的權(quán)重,從0.4到0.8以0.1遞進。縱軸為極樂disco畫風lora,從0.4到0.8以0.1遞進。

漢服lora測試中,橫軸為漢服lora權(quán)重,從0.4到0.8以0.1遞進??v軸為極樂disco畫風lora,從0.6到1.0以0.1遞進。其中權(quán)重偏差為額外測試所得,超出該范圍可能導(dǎo)致畫面崩潰。

在測試過程中,明顯感覺對人物lora兼容性稍差,在無數(shù)次調(diào)整后確認權(quán)重在0.4到0.8之間才能有比較好的畫面效果,并且使用人物lora時需要稍大的畫幅,不然可能會導(dǎo)致面部崩潰。

漢服lora則出現(xiàn)了一些蓋過原畫風的問題,因為再開大權(quán)重可能導(dǎo)致面部變形,所以也無法通過改變權(quán)重解決問題。不過在畫面融合時依然產(chǎn)生了一些有趣的效果,也是一種不錯的嘗試。

結(jié)論

在人物肖像方面的表現(xiàn)讓人驚喜,在稍低重繪幅度情況下完整的保留了極樂disco風格的筆觸,對原始人物面部有輕微影響。在稍高重繪幅度情況下則偏向模型的訓(xùn)練集風格,人物開始偏向西方人種特征,即便提示詞中已經(jīng)有了相關(guān)的提示。

人物全身的生成方面則有些差強人意,雖然畫風依然保留,但已經(jīng)完全看不出原始人物特征,低重繪幅度情況下人臉崩潰情況嚴重,開高重繪又會極大降低還原度。具體使用時可以參控測試結(jié)果進行取舍。

場景方面則非常驚喜,無論是最開始對場景的還原,抑或是高重繪情況下對場景“極樂disco”化改造。都展現(xiàn)出了不俗的可能性,給了我不少靈感。在后續(xù)其他測試中,我也可能會嘗試用白模場景進行生成,看看它基于有限構(gòu)圖的創(chuàng)作能力。
