一说画透明材质啊

一说画透明材质啊 Whenever it comes to rendering transparent materials; figuring out how to convey transparency is always the trickiest part. 怎么画出透明感就是最头疼的问题了 Since the background is visible through the plastic bag itself, start by establishing the background first. 所以先处理好背景 Work on the background with a soft brush to create a soft, blurred effect. 背景可以用软笔刷处理 Work on the background with a soft brush to create a soft, blurred effect. 做出一种朦胧的感觉就行 The overall color palette is cool-toned, so pick a light blue to block in the shape of the plastic bag. 画面整体偏蓝 The overall color palette is cool-toned, so pick a light blue to block in the shape of the plastic bag. 所以可以选择一个浅蓝色 To block in the shape of the plastic bag. 用来画塑料袋的形状 You can simplify its silhouette into a trapezoid first, then refine the shape more accurately on top of that. 他整体的形状可以先理解成一个梯形 You can simplify its silhouette into a trapezoid first, then refine the shape more accurately on top of that. 然后再在这个基础上把他的形状修的更准 Even though the bag is transparent, it still needs to retain its 3D volume and form. 虽然这个袋子是透明的 Even though the bag is transparent, it still needs to retain its 3D volume and form. 但是该有的体积 Even though the bag is transparent, it still needs to retain its 3D volume and form. 他还是有的 Since the light source is distant, pick a bright tone and softly airbrush the right side to highlight it, darken the left side, then lower the layer opacity. 因为光是從远处来的 Since the light source is distant, pick a bright tone and softly airbrush the right side to highlight it, darken the left side, then lower the layer opacity. 选一个亮色 Since the light source is distant, pick a bright tone and softly airbrush the right side to highlight it, darken the left side, then lower the layer opacity. 用喷枪把右边这块轻轻提亮 Since the light source is distant, pick a bright tone and softly airbrush the right side to highlight it, darken the left side, then lower the layer opacity. 把左边压暗 Then lower the layer opacity. 再去把不透明度降低 Now that background we set up earlier, comes into play—this gives us the broad, general transparency effect. 我们一开始画的背景就派上用场了 Now that background we set up earlier, comes into play—this gives us the broad, general transparency effect. 这只是个大的透明效果 Looking closely, you'll notice that the lit areas have weaker transparency and higher luminosity/highlights. 仔细看我们就能发现 Looking closely, you'll notice that the lit areas have weaker transparency and higher luminosity/highlights. 他的受光面的透明感很弱 Looking closely, you'll notice that the lit areas have weaker transparency and higher luminosity/highlights. 亮度比较高 Switch to a hard brush here to define and block in the shapes of the illuminated planes. 这里用一个硬笔 Switch to a hard brush here to define and block in the shapes of the illuminated planes. 把他的受光面的形状概括一下 Using a hard brush keeps the edges crispy, which fits the material properties of plastic. Soft or fuzzy edges would lose that sleek plastic feel. 用硬笔就是为了让这个形状的边缘更干净 Using a hard brush keeps the edges crispy, which fits the material properties of plastic. Soft or fuzzy edges would lose that sleek plastic feel. 符合他这个材质的特征 Using a hard brush keeps the edges crispy, which fits the material properties of plastic. Soft or fuzzy edges would lose that sleek plastic feel. 有太多毛边的话就没有这种感觉了 Don't worry if you can't place these shapes perfectly right away. Block in a few key shapes first, then use the distance between them as a guide to adjust the overall form. 找不准这些形状的位置没关系 Don't worry if you can't place these shapes perfectly right away. Block in a few key shapes first, then use the distance between them as a guide to adjust the overall form. 先画几个出来 Don't worry if you can't place these shapes perfectly right away. Block in a few key shapes first, then use the distance between them as a guide to adjust the overall form. 然后再通过这些形状之间的距离作为参考 To adjust the overall form. 再去调整他的造型 The bag is filled with water, which reflects the surrounding environment. 他这个袋子里是有水的 The bag is filled with water, which reflects the surrounding environment. 袋里的水反射了周围的环境 To render these environmental reflections, lightly airbrush over the bag—you just want to capture the subtle color bleed, so there's no need for crisp detail here. 表现这个反射就直接用喷枪 To render these environmental reflections, lightly airbrush over the bag—you just want to capture the subtle color bleed, so there's no need for crisp detail here. 在这个袋子上喷一喷 To render these environmental reflections, lightly airbrush over the bag—you just want to capture the subtle color bleed, so there's no need for crisp detail here. 要的就是他这个感觉 So there's no need for crisp detail here. 所以不用把他的细节画得很清晰 Next up is the fish. Block in the body using a simple quadrilateral, then build out the rest of the anatomy onto that base shape. 然后就是鱼 Next up is the fish. Block in the body using a simple quadrilateral, then build out the rest of the anatomy onto that base shape. 鱼的身体部分的可以用四边形概括出来 Then build out the rest of the anatomy onto that base shape. 然后在 Quickly establish the fish's form using an airbrush. Airbrushes are super effective for rendering curved, organic structures. 还是用喷枪快速的处理出鱼的体积 Quickly establish the fish's form using an airbrush. Airbrushes are super effective for rendering curved, organic structures. 喷枪在处理一些曲面结构的时候是非常好用的 Once the main volume is down, refine the structure with a hard brush. Detail the gills, fins, and eyes, adding distinct brushstrokes at key structural turns. 有体积之后 Once the main volume is down, refine the structure with a hard brush. Detail the gills, fins, and eyes, adding distinct brushstrokes at key structural turns. 再用硬笔处理鱼的结构就比较容易了 Detail the gills, fins, and eyes, adding distinct brushstrokes at key structural turns. 把他的鱼鳃 Detail the gills, fins, and eyes, adding distinct brushstrokes at key structural turns. 眼睛这些地方具体的画一画 And adding distinct brushstrokes at key structural turns. 以及在一些他的结构转折处稍微加一些笔触 Now return to enrich the highlights on the bag. To make the plastic look even more transparent, push the darks along the shadow side and the water level boundary using the background color—locking in those edges with strong value contrast. 然后 Now return to enrich the highlights on the bag. To make the plastic look even more transparent, push the darks along the shadow side and the water level boundary using the background color—locking in those edges with strong value contrast. 要预想袋子的透明感更强的话 Push the darks along the shadow side and the water level boundary using the background color—locking in those edges with strong value contrast. 我们就用背景的颜色 Using the background color—locking in those edges with strong value contrast. 加重他这个袋子的暗面 And the water level boundary using the background color—locking in those edges with strong value contrast. 以及水的边界 Locking in those edges with strong value contrast. 就是通过这个明暗对比把这个边界卡出来 At this stage, use texture brushes to add extra visual detail, like using subtle texture strokes to capture the complex environmental reflections. 就能用一些纹理笔刷丰富一下信息量 At this stage, use texture brushes to add extra visual detail, like using subtle texture strokes to capture the complex environmental reflections. 就比如他反射的这个环境 Like using subtle texture strokes to capture the complex environmental reflections. 就能用纹理来表现 Finally, polish the overall piece by adding tiny details like water droplets. And with that, the illustration is complete! 最后就是整体的处理一下画面细节 Finally, polish the overall piece by adding tiny details like water droplets. And with that, the illustration is complete! 比如小水珠什么的 And with that, the illustration is complete! 到这这张图就画完了 Alright, I'm Miaomiao! See you next time! 好吧，我是喵喵 Alright, I'm Miaomiao! See you next time! 我们下次见
