AI is tool, not magic button: ZiMAD details use of Stable Diffusion and Photoshop to create art for mobile games

Andrey Novikov
When I started my profession in design, the market supplied considerably much less software program to select from, and the out there instruments had been very restricted on the time. And though we now have as a lot monotonous work, the consistently growing instruments assist us alleviate it.
That’s why it’s so vital to continue to learn. Always. Currently, I use Photoshop with built-in AI and Stable Diffusion (along with a number of instruments for artists) in my work.
I began studying the latter by means of manuals I discovered on-line. I couldn’t obtain all of the information I wanted in a single pack again then. My data wasn’t systematized, so I even  determined to end a course on Stable Diffusion.
Would I counsel doing the identical?
Sure. Though being a pioneer is honorable, having a chance to study from an professional who is prepared to share is a lot extra handy. For instance, a course can shorten your journey from two weeks to two days: it’s going to offer you all the data you want and the fundamental data, utilizing which you can begin working with a brand new device straight away.
Stable Diffusion is arrange regionally in your pc: you want to set up Python, run the compiler, get a hyperlink, and comply with it to open the net model of the interface.

However, you’ll be able to use different interfaces — the selection is up to the consumer. Stable Diffusion options a number of settings, and it’s vital to know the way every of them works. They are not the standard buttons in Photoshop, the place you’ll be able to determine what a device does by its icon. Alternative interfaces embrace Easy Diffusion, Vlad Diffusion, and NMKD Stable Diffusion GUI.
AI gives the end result virtually immediately — it’s not rendering that offers you adequate time to go to the kitchen and have a chat with colleagues by the cooler. To work with AI quick, it wants to be arrange for your targets.
AI coaching
Smooth work with AI is the end result of coaching.
For instance, I wanted the mannequin to find a way to generate an inside in a particular type. To do that:

I took photos of one of ZiMAD’s initiatives, Puzzle Villa;
Cropped them into smaller segments so that every fragment featured a component of inside design;
Let AI interpret what it sees within the photos — at this stage, it’s vital to estimate the accuracy of knowledge and repair it, if wanted (if you happen to skip this step, the community will hold producing incorrect outcomes: e.g, if it errors a dresser for an individual, what is going to it provide you with if you happen to ask for a dresser? — appropriate, an individual); 
After the coaching course of, you find yourself with a definite type.

You may also share it along with your colleagues to make your pictures constant. They solely want to have a particular key to management or modify the habits of AI algorithms.
So right here’s the method of working with AI in a nutshell:

Show the AI device 50+ pictures, describe them, and get a brand new type;
Apply the type to the photographs that require modification;
The illustrator works on the details.

1 — preliminary picture; 2 — styled picture; 3 — picture reworked by an illustrator
Prompts: key to interacting with AI
If you need to get nice, high-quality outcomes from working with AI, then studying how to work with prompts — textual content inquiries — is a should for you. They have to be formulated as exactly as potential.
Each immediate is distinctive, and any little factor can have an effect on the end result, so it’s extremely vital to comply with the right phrase order and use phrases and types rigorously.

I don’t advocate utilizing solely prompts. You can throw pictures at AI, which, personally, is simpler for me than explaining one thing by means of a textual content. Let’s say, I would like an image of a particular cat.
I ship AI the cat and inform it I would like a cat in a hat. But the possibilities the AI will give me what I need are shut to zero. To increase the method, I could make a sketch of a hat in Photoshop, ship it to AI for processing, and modify such settings because the quantity of variations and the extent of details.   

I choose the realm for AI to work with utilizing the Inpaint device and modify the required settings just like the quantity of variations, the extent of details, and an important setting on this case — denoising power that defines how a lot AI will stick to my sketch, the place 0 means it’s going to not make any adjustments in any respect and 1.0 means it’s going to ignore my sketch and draw no matter it desires.
After that, I get a number of variations of the cat in a hat, and I select the one which I favor.

Here is one other instance of utilizing AI to considerably pace up sure work processes.
A 2D Artist wanted to create a novel UI for an occasion. The artist made a sketch, I ran it by means of AI and described all of the details offered by the artist in a immediate. After that, we immediately bought an ideal fundamental image to work on.  

Boxes with apples, stairs, and sheep within the image had been generated individually to obtain a extra predictable end result appropriate for additional transforming.
Another highly effective path of work is becoming a member of 3D graphics and AI. Right now, I’ve duties for producing sure small areas. AI works properly with interiors, however perspective typically fails. In my case, I would like a particular angle, so right here is what I do.
First I mannequin a scene in 3D, prepare the objects across the scene and place the digital camera, render the depth map, and get the next picture.

The second step is to add the depth map right into a particular part known as ControlNet, set the settings in order that the neural community generates pictures based mostly on this specific depth map preserving the angle and location of objects. Then I describe a darkish, cluttered attic, with a skylight and a cardboard field within the middle of the body in a immediate, and I get the next picture.

After that, I finalize the ambiance in graphic editors based mostly on the technical specs. According to the outline, I ought to find yourself with the picture of a tragic cat asking for assist whereas in a darkish, scary attic on a wet evening throughout a extreme thunderstorm. I get a picture that I can go on to the animator for additional work.

Value of AI for artists
AI instruments assist create fundamental pictures which you can polish as you would like, focusing extra on the image reasonably than on technical work.
In the previous, if I had to draw 20 avatars, right here’s how the method would go:

Looking for references;
Drawing sketches;
Working on every avatar individually from scratch;
Gradually including details to every avatar.

Now AI does most of this work for me, and it’s way more efficient and quicker.
Once the type of the undertaking is prepared, it normally takes me solely 5-7 minutes to generate 20-30 choices of a sport avatar to select from. Generating 10 avatars with the identical quantity of choices takes about an hour. 
In basic, I actually like how AI is built-in into my working processes. With AI, I can full extra duties than I used to after I labored solely with a graphic editor, which makes AI an ideal device. But it’s nonetheless a device and not a magic button that threatens to depart artists with out work.
Different AI instruments completely praise one another. For occasion, Stable Diffusion works higher with informal graphics, and Photoshop is nice for sensible pictures, and its built-in AI is fairly useful as properly. However, its outcomes are not as predictable as in Stable Diffusion as a result of there aren’t any settings other than prompts.
For instance, when you have an attention-grabbing picture that can’t be cropped as you would like, you’ll be able to draw the lacking half proper in Photoshop in a short time. In Stable Diffusion, such a job requires extra effort. 
Midjourney can create wonderful fantasy photos, however, sadly, their decision is removed from first rate. That’s why at ZiMAD, we use Stable Diffusion to improve decision. The coolest factor about it is that it presents an possibility to depart the picture untouched, whereas bettering its decision and including some details, if wanted.
My colleague used Midjourney to create a gorgeous image for Magic Jigsaw Puzzles, and I elevated its decision to 4K in Stable Diffusion. AI added details with out altering the preliminary image. The wolf bought high-quality fur, and pixels had been eradicated.
In such instances, I use the Script area. I choose one of the proposed upscalers, in our case it is LDSR, set the Scale Factor parameter, which determines what number of instances the picture shall be enlarged. I additionally keep in mind to set the Denoising Strength parameter to close to minimal values. If this parameter is set too excessive, the neural community will significantly redraw the image. The values for upscaling in our case are 0.1-0.2, right here is an instance of what occurs if you happen to depart a excessive Denoising Strength parameter when upscaling a picture.

After setting a great denoise parameter, the neural community accomplished the details with out altering the general image. For instance, this is how the wolf bought high-quality fur, and pixels had been eradicated.

Even although Stable Diffusion works nice with parts of nature. It nonetheless struggles with structure and inscriptions. Buildings could prove chaotic, and the textual content — unreadable. Here are some makes an attempt to create a emblem utilizing AI.

Neural networks will hold getting extra complicated and present extra alternatives for fast and efficient work with pictures. Implementing them into your work is very important for staying aggressive.
In the close to future, I’m planning to create a pack of 50 icons in Stable Diffusion. If I had been to do that manually, it might take me over per week, whereas with AI I can full this job in about two days.
The benefit is simple, isn’t it? So as an alternative of resisting new know-how, we must always find out how to successfully apply it.
