ArtStudio is just too good not to leave a review for. I’ve been using Photoshop on my PC for drawing, photo editing, and professional work for the past six years and when I finally got an iPad with Apple Pencil support I was really hoping Procreate or one of the numerous other drawing/editing apps would be able to replace the feel of PS. Unfortunately, even though Procreate is indeed an amazing drawing program, it still doesn’t really satisfy my need for the familiar feel of photoshop and drawing with photoshop brushes. ArtStudio Pro solved all my problems. It’s got everything you could need and MORE (I especially love their amazing smoothing/line weight algorithm and pressure customization). It’s basically Photoshop, but without having to pay the ridiculous Adobe subscription every month. The price for this app is perfect, in my opinion (and honestly it’s even a bit low, for all it’s able to accomplish) and I really want to give a huge thank you to everyone who worked on/is working on this app and updating it. You’ve saved me so much money and frustration. Hats of to you!
Pretty good post. Thanks to blog author for the wonderful and informative post You may also read the website - http://www.coloradoloansnearme.com
Woo Kim talked about his stunning VFX made for Dungeon Hunter Champions: splash, character and background animation, shaders, the path of generalists and more.
Salut! My name is Woo Kim, and I’m from Korea. I’m working as Senior VFX Artist at Gameloft Montreal. Recently I’ve been participating in Dungeon Hunter Champions project. My main role is making VFX for UI, but I also make some in-game VFX.
My career path is a little bit complicated.
At the very beginning, I was a General 3D character artist. I did concept art, modeling, texturing, rigging, and animating. When I started working at my first company, I didn’t know anything and could only do drawing with pencil on the paper. So it was super hard because I had to learn multiple software solutions at the same time and do everything on my own. But I learned many things and I began dreaming about being game art generalist. As a result, I tried to establish my own company (and become Art Director) but completely failed. So I ran away from the game industry and became a motion graphic designer. Two years later when I received an offer from a game company, I hesitated. However, my love for game art eventually made me come back to the game industry.
I made a lot of videos within a couple of years, that’s why the companies invited me to be a VFX Artist. At that time, I found a lot of fun in the game VFX field and it perfectly fit my skillset because I had some knowledge of FX, 2D & 3D art, motion graphics, and some script. However, I also had a desire to be a UI Artist because I majored in visual communication design (though dropped out during the last semester) and learned about UI.
Luckily, I got a UI / VFX artist position. I remotely worked as Art Director at a Thailand company and also became a UI Art Team Lead lead at one of the major companies in Korea. After another couple of months, I received an offer from Gameloft.
Some people said my career was too messy, but I can’t agree with that. I think game art isn’t a separate thing, but more organic, and learning various areas of it is increasingly crucial.
I made the animation below from only one illustration, so I had to detach every single part and repaint the background. It was the toughest and most boring part.

Usually, I prefer to work on the project without any extra plugins as much as it’s possible. Extra plugins can save time and ease the process, but they are not perfect for tiny modification. That’s why I rigged every part through expression (script) with built-in effects by myself.

If you want to create a cool animation with After Effect, here are 5 essential functions you should know: puppet tool, mesh warp, 3D layer, expression controllers, and script. That’s all.
But a technique is just a technique. I know it’s a cliche but the most important factor is the sense of expression and motion. You should keep observing everything that moves around you and anatomize well-made artworks to enhance your skills.
When I animate something, the first thing that I do is set the personality of the character. Is she/he composed or pugnacious, thin or heavy, angry or happy? I also imagine the action that has happened right before the current scene, because animation is not isolated. It has its own flow, continuity, narrative, and tells a story to the viewer. Thinking about the source of the current motion will give you extra room for storytelling. You also have to consider the atmosphere: crowded, sacred, ruined, battlefield, etc. The story depends on the environment. After the personality of the scene is set, details appear naturally.

For example, the Bounty hunter usually has a fiery temper, but on the loading screen when he is simply preparing for battle expressing madness will be odd. Therefore, I animated him as heavy and taciturn with inner anger. By contrast, the personality of Frog Ninja is playful and funny, and I don’t want to make him look serious.

You shouldn’t disobey the principles of the real world too much. We can tweak gravity, elasticity, and friction depending on the genre, but there is always a line. If you cross it (especially unintendedly), the viewer may feel uncomfortable. It will feel fake, ruin the character and interrupt the viewer’s immersion into the story.
Arm animation for Bounty Hunter, Cartoonic Ink, Cartoonic Water (All rights reserved @Gameloft Montreal)
For example, when the Bounty hunter is smashing a demon on the ground, the animation follows physics and isn’t exaggerated too much. On the contrary, ink and water behavior differs from reality because of the art style, yet is kept within the boundaries and tries to imitate real-life liquid main features.
Finger and hair rigging with Null objects & Scripts (All rights reserved @Gameloft Montreal)
I would love to use some black magic, but as I said before, there is no one-click solution for it. I divide meshes, pin bones, link them through the script, and animate them with the keyframe.
Pre-rendered sequences (All rights reserved @Gameloft Montreal)
Sometimes I use pre-rendered cloth simulation and 3D animation in 3ds Max. But as you’ve noticed, most of my work has a cartoonish style, and in this case, realistic simulated effects or materials (such as fabric, hair, water, etc.) don’t fit.
The background art is my favorite. It was made by Sergey Samarskiy, he is a really great artist. The images are integrated into the actual engine. In contrast to the splash art animation, here I had to seriously think about optimization and take care of it. I needed to consider the size of textures, polygon counts, draw calls and the actual situation around VFX. The main goal was to make the scene abundant but not distracting since it’s a background, and the champions in front are more important.
To achieve the goal, I set some rules:
- There should be a large-scale but slow movement
- The lighting and the color of the sky should not be too intense
- The background should have its own rhythm for the entire effect & motion
Forest theme (All rights reserved @Gameloft Montreal)
The forest theme is my favorite background. I wanted to make a peaceful forest with a plenty of tiny movements. Most of the time everything is moving slowly, but sometimes a few things speed up or get closer to the camera. These moments are unexpected and break the boring looping feeling.
Another thing I like to make is 3D looking art pieces with an orthographic projection. You can check a few 3D animated flat meshes below.

As you’ve noticed, those are just flattened meshes. But you can express the movement and the dimension in completely different ways, for example with skinning. It takes a considerable amount of time and effort but it’s worth it.
A Shader Instead of Lighting
I didn’t use lighting components at all. I know it looks like lighting but in fact, I just used a shader.
Even though the skies below are changing slowly andinsignificantly, the changes are taking place within wide areas. Overlapping a large area caused an overload, so I’ve tried to use a simple shader instead. Technically, it just a mixture of 2 textures or one distorting texture.

It was a really interesting work, and I want to give credits to my art director Remi Despret. Without his support, I wouldn’t be able to make it. Merci beaucoup!
I played with Shader Forge for a couple of days when I began to learn shaders. Visual scripting is very handy and I believe it will take a huge part of tech art in the future. But I think it isn’t the best way to fully understand how graphics work. You can achieve a good result via visual scripting tool but if you want to make something awesome that you haven’t seen before, you have to invest your time into studying the fundamentals. I’ve been trying to write custom shader by myself without any plugin. Of course, it is a tough way with a lot of pain and stress if you have an artistic mind. But as you start understanding the nodes and the logic behind them, you are able to make greater artworks. The knowledge of shaders unlocks our imagination, and it actually had a positive effect on my creativity.
I’m not a veteran of tech art, so I am very cautious about giving a piece of advice. I just want to say “don’t try to find an easy way and deal with the challenges right away. Spend time on studying the shading language itself rather than browsing how to avoid doing it. Tools are constantly changing but fundamental techniques and the basic knowledge will not change that easily (at least within a decade).
The Trick Behind the Sphere
The sphere was made with UV mapping trick. I previously wrote an article about it in Korean, so if you know Korean check it here.
An example from the article:
The trick is simple. I slightly tweaked the angle of the spherical UV map and rendered the part behind the sphere in another pass. It moves in the opposite direction to make my sphere look more like 3D. Any other decorations are made without any tricks. I played with the vertex position, vertex color, rotating UVs, etc. I controlled every property in each object by C# script.
Advice for Future Generalists
I find becoming and being a generalist quite hard, and I’ve been struggling every single moment on the way to this goal. But I want to cheer up the people who are on the same path. It’s very tough, it may deprive you of the well-balanced life, and sometimes other people can underestimate your skills. 2 or 3 years ago I often heard some words like “so, what’s your specialty? Sorry, we don’t need all round handyman.” I found it rude. But right now I know that I have my own special field. It isn’t a common area, and only a few people specialize in it because it’s not an easy one. This area is for professionals who have wide knowledge. So, if you are interested in varying the working fields, expanding the knowledge and skills and feel delighted with being able to handle different tasks, just keep going straight ahead – this is your talent. Just keep in mind three principles:
- Don’t care about negative outside interference. Be brave!
- Carefully choose the subject to learn. There’s always a lack of time because we have to study so many things, so beware of wasting time. Don’t follow trendy tools and be focused on fundamental knowledge first.
- Enjoy your work. Naturally, you’ll be stressed out while creating, but making what you really love and feel passionate about will help you to get rid of the stress.
Thanks for reading my story. Keep it up!
