CG painting must be very familiar to everyone. There are many such workers in life and online, If you want to master CG painting, you must learn it first, so that you can have more knowledge about CG painting. Skills and steps must be systematically learned. So today's editor will introduce you to the introductory tutorial of cg illustration. Let's have a look.
Learn how to get started with CG illustration
1、 Platform environment: CG painting pen and paper are digital tablet and computer.
2、 Fundamentals of painting: Generally speaking, it is drawing and color. It's a matter of painting skills, which needs to be done slowly. Learn to sum up, use what you have learned in previous courses and sum up more in practice. How to learn the basics? (Basic human structure, character design, suit design, scene (atmosphere, probability) poster synthesis) First of all, basic human body basics are all available, so at least you must have a certain understanding of these, right? To remember, to understand, to paint, there is no other way.
Initial stage: The feeling of hard work is inevitable, but don't give up. At the initial stage, you can copy some photos or works. In order to increase your motivation, you can choose to copy and write your favorite star cartoon characters. Copying is not copying, but on the basis of your ability to be accurate, and the relationship between sketch and color is clear. Don't expect you to draw exactly the same picture. It's a dead end and a waste of time in the end. During this period, you began to know how to draw CG, that is, you had to write carefully, paint painstakingly, refine painstakingly, and have a sense of accomplishment.
Advanced: You can start half creation under the embrace of materials. You can learn the color matching, composition and character design of good works (don't say you are original). In this process, you will become more and more skilled and add your own understanding. And gradually formed their own style of painting, and good at painting the theme. At this stage, you should try your best to absorb the knowledge of various elements, such as the copy on the armor and the accessories on the boots, which have specific cultural backgrounds.
Introduction to cg illustration
1. Sketch. There is no line drawing here. Instead, create a new layer on the black background and use a white brush to compose the picture. At this stage, there is only a relationship between black and white. Analyzing the positions of light and dark parts is like making prints. I think that if a black and white picture can provide enough information, the story to be told in the final work will be relatively clear.
2. Color. This step is the most important for me, because the more we deal with colors and tones, the less we need to modify later. Although this step is to use rough strokes, there is not too much material performance. But if the light and shadow are handled correctly, the so-called "true" feeling will appear.
I follow the following principles about atmospheric perspective when I go up the light and dark:
From far to near, the details of an object disappear first, and then the color disappears. The outer contour is most difficult to blur unless the air is very turbid (such as the fog in the above figure).
The closer an object is, the warmer it will be. The farther it is, the colder it will be. The closer the object is, the stronger the light dark contrast will be. The farther the object is, the weaker the light dark contrast will be.
These principles sound simple, but in practice, they do not follow the pithy formula. The understanding of light, shadow and shape depends on muscles. Only in the continuous process of painting can specific problems be analyzed to make painting natural and smooth.
I use the clipping mask to draw all the bright colors in the bright (white) layer, and the dark colors are all clipped in the dark layer, so that the colors will not be painted everywhere.
3. Overlay photos. This is indeed an ingenious technique, but the important thing is not the photo, but the last step. The light and shadow processing in the last step is good, and it is difficult to make mistakes in any creative method. If your light and shadow are wrong, it is useless to stack more photos.
The same is true for overlapping photos. The light part is stacked on the light part with the clipping mask, and the dark part is stacked on the dark part. I usually use two layer modes to stack photos, Softlight soft light and darken darken. The soft light coating has little effect on the light and shade contrast of the layer below it, and is suitable for adding small details, such as grass texture. Darken only displays pixels whose layer is darker than the layer below. It is very useful when I need to create large modeling details such as stone cracks.
4. Continue to find the shape. Once you have the basic texture, you can start to process the details. Find out the ambiguous structural relationships in the material, and then slowly process them into the shape you want. At the same time, in this process, the story depicted in your mind will be clearer, and you can start to think about the meaning of each shape to the story when painting.
The clear dark composition at the beginning and a method of smearing in the clipping mask show one advantage, that is, the simple composition you designed at the beginning will not be destroyed too much when you paint details, because most of the smearing you do is in the shape that has been specified, and it is difficult to overflow the scope of large regulations.
5. Finally, use PS. Although we always use PS to draw pictures, now that we are almost done, we can use PS's various painting skills to make the picture sharper. Enhance the contrast of main objects and guide the audience's line of sight. You can save it when you feel comfortable.
Notes on learning CG illustration
1. Not suitable for digital board? Just use it more!
Digital tablet can be said to be the key in CG painting. Many beautiful CG paintings are made by painters with digital tablet. But after all, the digital board is not paper and pen, and its operation process and feel are completely different from that of paper and pen, so we suggest that you must try to adapt to the use of digital board.
In particular, the line drawing skill is the focus of digital board painting. It is strongly recommended that novices practice more "one stroke" and try to make one stroke accurate, which means you are used to it.
2. Don't try to reach the sky
CG painting is simpler than hand painting in theory, but it is still a complicated profession. So the accumulation of practice is essential. Never expect to paint a masterpiece in a short time. It is impossible not to say so. Forcible attempts will produce a strong sense of frustration.
3. Use tools flexibly
One of the advantages of CG painting is the convenience of tools. For example, if we paint by hand in real life, if we want to draw a straight line, we must use a ruler, and if we want to draw a standard circle, we must use a compass. But in CG painting, only tools are needed to achieve the goal, especially software PS, which is the best. So we must explore the use of tools, which will greatly facilitate our work.
The above is about learning CG painting. I hope that the above content will enable you to know more about CG painting, CG painting is to master the skills step by step, so that you can learn more fluently. If you want to know more, you can continue to pay attention to this site.
