◆Introduction

Hello!! I'm Ichino Shijo who mainly sells 3D pose materials at CLIP STUDIO ASSETS.

This time, TIPS on "How to draw dynamic poses" are being recruited, and I am happy that my work "A little usable pose collection vol.1", which is familiar as a standard material, has exceeded 50000 DL. I will introduce how I usually make 3D pose materials.

It is difficult to draw a natural pose of the whole body, so I would like to use a 3D drawing doll, but it is difficult to operate it.

 

For your reference, please take a look at the "Pose collection that can be used for a while" series!

◆ ① Draft

This time, I will proceed with the assumption that I will create a new pose for drawing a standing picture.

However, the first thing to do is to draft rather than prepare a 3D drawing figure.

Even if you create a pose from scratch with a 3D drawing figure, it will definitely be easier to draw a rough concept to some extent.

If you operate the 3D drawing figure for a long time, the load on the CPU will increase and the operation will become heavy.

If you make the canvas size smaller, it is recommended because you can reduce the load on the CPU.

You can change the resolution of the canvas after the pose is completed, so first choose a size of about 600 x 800.

Roughly draw the concept of the pose as a draft.

To create an attractive pose that does not feel awkward,

❶ Be conscious of streamlining the flow of your body (red line)

❷ Twist the torso so that the left and right shoulders and hips are closer and the other side is farther away (blue line)

❸ Create an exaggerated warp (green line)

It is effective if you are conscious of the per point.

◆② Basic operation of 3D drawing figure + angle adjustment

I will explain again how to operate a basic 3D drawing figure.

If you have a good understanding of other TIPS, you may skip this section as appropriate.

The 3D drawing figure is in the "3D" → "Body shape" tab of the "Material" palette.

If you drag and drop from here to the canvas, the 3D drawing figure will be reflected in the canvas.

The blue icon displayed at the top of the 3D drawing figure is the "movement manipulator".

Click + drag here to adjust the camera angle and the position of the 3D object.

Especially frequently used "Rotate camera" and "Move camera back and forth" have the same effect by left-clicking + dragging and right-clicking + dragging, respectively.

In addition, you can adjust the "perspective" by rotating the cursor wheel.

A setting of 1.0 gives a telephoto-like effect with no perspective, and as the number increases from there, the perspective becomes more and more dynamic.

First, use these to move the camera so that the angle is similar to the pose you want to create.

 

Before moving on to working with 3D drawing figures, let me briefly explain the characteristics of 3D drawing figures.

You can move the joints of the 3D drawing figure by clicking and dragging the parts or operating the manipulator, but there are some behaviors that you should be aware of in order to move them as you wish.

First, the default 3D drawing figure is fixed based on the pelvic joint.

So if you want to move both legs by clicking and dragging, this is enough to operate, but if you do the same operation with the upper body such as the head and arms, the whole body will be pulled and it will not work as expected.

When adjusting the upper body by clicking and dragging, it is necessary to change the fixed joints to eliminate this specification. I'll show you how to do that in a later step.

A single click on a joint reveals a "manipulator" consisting of three circles.

If you operate the manipulator in this state, you can move only that joint, but if you try to create a pose with this operation from the beginning, it tends to be an unnatural pose that ignores the movement of muscles and the center of gravity.

 

Click the joint twice to display the "animation controller" consisting of multiple blue circles, and the "root manipulator" consisting of four circles and six arrows.

By clicking and dragging the animation controller, you can move multiple joints to adjust the position of the arms, legs, torso, and line of sight, and you can add a twist to the torso by operating the manipulator that appears after clicking. increase.

If you want to roughly adjust the pose, we recommend using this operation.

In particular, the torso animation controller is very useful for creating attractive poses.

You can easily create the `curve'' and `twist of the torso so that the left and right shoulders and hips are close together, and the other side is away'', which I pointed out earlier when drawing a rough draft.

 

On the other hand, it is difficult to ignore the range of motion of the human body when using animation controllers.

It's easy to see if you move your arms, but it doesn't matter if the joints are buried in your body.

Regarding the ignored range of motion, if you move the joint with other operations, it will correct it so that it does not exceed the limit, but this may cause the pose you have created to collapse greatly. Keep that in mind.

◆ ③ Roughly create the overall pose

Based on the characteristics of the 3D drawing figure, let's start by roughly approaching the draft pose.

 

The legs are directly dragged, and the arms are moved to approximate positions using the animation controller.

Also, by moving the angle to the side once and pulling the animation controller on the torso forward, you can create a lively posture with your chest puffed out.

Conversely, if you want to create a pose that looks like you're stepping forward, you can bend your waist or drop it by pulling it back or down.

The animation controller, which is only one place away, moves the line of sight. You can also adjust the tilt of the neck, so let's adjust it to the right angle.

I made a rough pose.

We'll work out the details from here.

◆ ④ Adjust the legs

As mentioned earlier, the 3D drawing figure is fixed at the pelvis by default, so we recommend starting with the legs.

Click on the thigh joint and operate the manipulator to open the legs.

Basically, it looks better if each leg is turned slightly outward.

In the case of female characters, depending on how the legs are spread or bent, it would be nice to have them slightly tucked in.

If you move the knee joint by clicking + dragging, it will move with a little slack so that it will stand upright naturally, but you can use the manipulator to make it more taut. It will be in a state where it is slightly reversed joint by force. Please be aware of the "warp" that I pointed out in the draft and adjust accordingly.

It is also important to adjust the joints of the feet so that the feet are firmly on the ground. It is easy to do if you set the perspective to 1.0 once and operate at an angle where the grid looks horizontal.

While adjusting the part that protrudes below the grid, press "Place the model on the floor" in the "Object Launcher" displayed at the bottom of the 3D drawing figure each time to check whether it is well grounded. .

◆ ⑤ Adjust the arms and fingers

I will introduce how to operate the arm well by clicking + dragging, which I touched on earlier.

 

❶ Click the chest joint.

❷ Click “Toggle whether to fix the selected joint” in the Object Launcher.

❸ Click the belly joint just below the chest.

❹ Fix the joint by the same operation as ❷ .

 

Then you can move only the arm by clicking + dragging.

If you drag the shoulder, you can move the body a little, but other than that, you can operate it comfortably, making it very easy to adjust. It's worth remembering.

If you try to move the leg by clicking + dragging in this state, the torso will be pulled instead.

Be conscious of switching the joints to be fixed according to the part you want to adjust.

Once the arm positions are adjusted, the next step is to make the hand poses in detail.

Since there is a "hand pose" item in the "Tool Property" palette, let's first use this to open and hold the hand.

If you select a joint on one arm, the hand pose operation will be applied only to that hand. Be careful not to overwrite the pose of one hand that you have worked so hard to make with the adjustment of the other hand.

For fine adjustments of the fingers, you can click the chain icon at the top of the hand pose to operate the degree of opening for each finger. You can also operate with fixed.

 

❶ Unlock all joints from the object launcher.

❷ Click the joint of the palm.

❸ Fix the joint.

❹ Click the forearm joint.

❺ Fix the joint.

 

Then you can move your finger by clicking + dragging.

If you move fingers other than the middle finger, the palm will also move to some extent, but in general you will be able to bend and stretch comfortably.

Use the manipulator to adjust the details.

As a natural and attractive finger movement, you should be conscious of adding a different flow to each finger.

In particular, the index finger and middle finger should be stressed, while the ring finger and pinky finger should be slightly relaxed to allow natural finger movement.

 

◆ ⑥ Adjust the head

If you fix the two joints on the chest in the same way as when adjusting the arms, you can move the head by clicking and dragging.

The joints of the head and neck have a wider range of motion than other parts, so they are delicate, and it is easier to move them intuitively by clicking the top of the head rather than the area around the chin.

The angle of the head and neck has already been decided in step 3, but let's adjust it to make it more natural.

After making some fine adjustments, the pose turned out like this.

If you can make an attractive pose from various angles, it's complete!

If you make the perspective stronger, you can also bring out a different flavor.

You can easily draw dynamic poses with this.

◆ ⑦ Register as a pose material

It is recommended that you register a well-made pose as a material so that it can be reused.

This time, I created the poses from scratch, but if you apply the pose materials to the 3D drawing figures in advance and then adjust the details, it will be possible to create various poses in a shorter time.

 

Before registering the pose material, save the thumbnail image.

Select "Change image resolution" or "Change canvas size" from the "Edit" tab and enter the canvas size so that it is 240 x 240.

It is easier to change the resolution after changing the ratio to square with "Change Canvas Size".

Save the resulting 240 x 240 canvas in jpg format.

After you have saved the image, click "Register whole body pose as material" from the object launcher.

"Material properties" will open, so enter the necessary information.

If you specify the name of the material, it will be easier to find it in a search.

Click the file button next to "Material image" and open the thumbnail image you saved earlier. This makes it easier to see what kind of pose it is from the material list.

It is recommended to select "3D" → "Pose" → "Whole body" for "Save material destination" on the right.

 

It will be easier to narrow down the search tags if you refer to other downloadable materials.

To give you a reference for my personal tagging standards, I put "3D" on all pose materials, and "whole body" or "hands" to narrow down whether it's a full-body pose or a hand-only pose.

In addition, "standing", "sitting", "holding", "battle", "battle", "action", "jumping", "floating", etc.

The "Pose collection that can be used for a while" series contains floating poses every time.

◆⑧ Adjustments for practical use

Well, the explanation as "how to make pose material" is over, but the material is just the material.

The final goal is to use this to complete the illustration.

So, I will also explain the adjustment method when assuming "adjustment after applying the pose material".

You can adjust the body shape of the 3D drawing figure from the "Tool Property" palette.

It is possible to create a body shape that matches your drawing style, but doing so often makes the applied pose look unreliable.

Rather than using the pose material as is, we recommend adjusting it according to your body shape.

Use the animation controller to adjust the pose so that it looks good.

In particular, poses with crossed arms and legs or hands on the legs have large errors depending on the body shape, so it is important to correct them each time!

Depending on the pose, there may be times when you want to take atari including belongings and equipment.

In such cases, 3D primitives are useful.

Various shapes are included in the “3D” → “Primitive” tab of the “Material” palette, so drag and drop them onto the canvas.

3D primitives can be freely adjusted in size and length by operating manipulators.

For example, you can stretch a "square column" into an elongated shape, rotate it, and move it so that it fits in the palm of your hand.

It can also be used as a guide for high heels by reducing it, copying and pasting it, and moving it to both heels. By adjusting the angle of the heel again based on this primitive, it's easy to create a nicely grounded high-heeled pose.

 

In addition, 3D primitives can do various things depending on the idea.

It is also applied to the thumbnails of each pose included in the "Pose Collection", so please refer to it.

After finishing the final adjustments to the pose, let's change the image resolution.

Layers reflecting 3D objects behave like raster images when not selected.

If the operation is still slow and unbearable, right-click the layer and select "Rasterize" to completely rasterize it.

However, if you do that, the area outside the canvas will be cut off, and you won't be able to correct the pose later, so this is only a last resort.

All you have to do is draw a picture while standing on the 3D drawing doll!

Thank you for your hard work!!

 

Please refer to these TIPS and use drawing figures and pose materials!!

And eventually, let's sell materials and help other creators!!
