From Clip Studio Paint Ver. 2.2 and later you can set hierarchical relationships to your 3D materials.
This means that you can now attach accessories like hats and glasses to your 3D drawing figure and pose them together. Put a sword in your character’s hand and change the pose without fear.
You can also move multiple 3D models at once and display or hide them.
You can set parent-child relationships to 3D models to link them together. You can even link multiple 3D objects under a parent 3D model to move with the parent object.
Clip files with this hierarchy set cannot be edited in Clip Studio Paint Ver.2.1 or earlier.
3D models that allow hierarchical settings
You can configure the parent-child relationships for the following 3D materials.
・3D drawing figures
・3D head models
A child material of a 3D material that has a parent-child relationship set in advance, such as a 3D background, cannot be set as a child material of another 3D model.
How to set a parent-child hierarchy
You can set it by going to the Sub Tool Detail palette > Object list.
Drag and drop the child 3D material onto the parent 3D material. On tablets, long press on the 3D material you would like as a child to drag it.
You can have multiple materials under one parent.
You can also set a material to be under the child material in the grandchild position.
If you want to get rid of this hierarchy, drag the material outside of the object list until you see a red line appear around the edges of the entire palette and then drop it.
You cannot edit this setting from Tool Property palette > Object list.
Using 3D models with multiple materials attached
Try to envision how you will use this to help your drawing workflow when setting up the materials.
Below we have the bicycle set as a parent and the child materials are the drawing figure, bicycle basket, and basketball.The drawing figure also has other materials set to them as children (grandchildren).
The materials set under the parent will move and rotate along with the parent.
If you move a material set as a child, the parent will not move with it.
The same goes for changing the scale using the gray ring.
If the scale of the parent is changed using the independent axis manipulator or the Tool Property or Sub Tool Detail palette, the scale of the child will not change.
Linking small props to the 3D drawing figure
Models that have joints like 3D drawing figures or 3D characters, can have materials attached as child materials to their hands or heads.
For instance, when you attach glasses to a 3D drawing figure head, the glasses will move along with the head.
You can attach materials to the following parts:
・Right and left upper arms/forearms
・Right and left hands
・Right and left thighs/calves
・Right and left feet
You can also set attachments to VRM models you have loaded into the app. Please refer to the following article on how to import a VRM model.
How to attach a material
1. Load the 3D material that you want onto the same layer as the 3D drawing figure, then set it as a child material by going to Sub Tool Detail palette > Object list. The position the material is in when loaded onto the canvas is not important at this point.
2. Select the child material from the Object list and select where you want the Attachment point to be. This will reposition the child material to the attachment point automatically.
3. Adjust where you want the prop to land on the attachment point area to finish. Now you can move the drawing figure and it will also move the prop attached to it.
Try moving around your model after attaching a prop to make sure that the attachment point positioning is correct. For example, when setting boots as an attachment it might seem natural to select feet, but actually calves offer more natural movement.
There are many 3D materials at your disposal on Clip Studio Assets for you to try out attaching to your model. Try out props like shoes, glasses, bows, hair, hats, collars, wings, swords, and more!
Attach a 3D head model to your 3D drawing figure
Attach a 3D head model to your 3D drawing figure to link the head model to the drawing figure body.
You’ll want to prepare the 3D drawing figure and 3D head model before trying to attach them to ensure a better fit.
Make the drawing figure’s head smaller
Make the 3D drawing figure head smaller and lengthen the neck to make it easier to place the head model on top.
Make the 3D head model neck thinner and shorter
The head model does not enable neck posing, so you should prioritize using the 3D drawing figure for the neck. Make the neck thinner and shorter so that it won’t stick out from the drawing figure.
