How to create import PSDs

(Updated 07/03/2020)

This page explains the preparations required after material separation and how to create import PSDs.

Please refer to “About Separating Materials” for the procedure of separating illustrations into parts such as eyelashes, eyeballs, outlines, and so on.


How to create import PSDs

Each component (group) created in the PSD for material separation is combined into a single layer.


Once all the parts are on a single layer, save as.
For file names, PSDs for material separation should be named “xxx_material_separation.psd”, PSDs for import should be named “xxx_import.psd”, etc. for easier management.
* When merging groups, be careful not to overwrite and save the merged layers in the materialized PSD.

It is a good idea to enter txxx at the end of the data name, with the xxx part increasing in number each time the PSD is updated.
(“t” means take).
It is also easier to manage the material separation and import txx numbers together.

A Photoshop split that can automatically merge layers is available.
Download the script from the “Scripts for Photoshop” page.


Points to note when creating PSDs for import

When creating PSDs for import, the following points should be noted.


Check for layers with the same name
Basically, the same layer name can be imported into the Cubism Editor, but
having the same layer name can cause confusion and lead to problems later on.
To avoid such problems, all the layers should be named differently in the material separation PSD stage.


Layer attributes after merging should be “Normal” or “Multiply”
Layer attributes other than “Normal” or “Multiply” may result in unintended color changes upon loading.

Layer attributes can be set on the Cubism Editor.
After importing, select the ArtMesh you wish to change and set the [Inspector] palette -> [Blend Mode].

• Normal
• Multiply * If the PSD is set to multiply, it will be automatically set to multiply when imported into the Cubism Editor.
• Additive

These three types can be set.


[Opacity] is set in the PSD and the percentage is reflected in the Cubism Editor, but [Fill] is set at 100%.

If [Opacity] is set to 50% in the PSD, the opacity will be set to 50% when imported into the Cubism Editor.
[Fill] is not reproduced in the Cubism Editor, so even if it is set to [50%], etc., it will be set to 100% in the Cubism Editor.
For cheek dyeing, for example, where the density needs to be adjusted, it is recommended to use [Opacity] instead of [Fill] to set the opacity.

Opacity can also be set on the Cubism Editor.
After importing, select the ArtMesh to be changed, then select the [Inspector] palette -> [Opacity] settings.


Combine line drawings and clipping masks
One part, one layer.
Line drawings, fills, filter effects, clipping, etc. are combined into a single layer.
* If you want to separate line drawings, shadows, etc., manage them as one part, one layer.


Layer masks are not used.
If layer masks remain, combine them into one with “Apply Layer Mask”.


Color mode is “RGB”, color profile is “sRGB”
If the color mode is set to something other than RGB, such as CMYK, PSDs cannot be read, so use RGB mode.
If the color profile is not sRGB, the colors may be incorrect when loaded, so use sRGB.
Please refer to the “Color Profiles in PSD” page for the conversion method.


Check for trash.
There may be some eraser residue or other debris left behind that is hard to notice, but even debris is recognized as a material.
Automatic mesh generation, etc. may not work properly, so be sure not to leave any trash behind, such as forgetting to turn it off.
Even if no debris remains, a large transparent area may cause unintended operation.
It is a good idea to use the lasso tool or other tools to select and delete non-material areas.
In Photoshop, you can change the display of layer thumbnails to get a rough idea of the current state of the material.


Check to see if path information is included.
If path information is included in a PSD created with Photoshop CC2019 or later versions, it may not import into the Cubism Editor.
If path information is included, it should be deleted before merging.
