High-quality lines in Blender

PSOFT® Pencil+® 4 Line for Blender is a post-processing effects add-on that adds lines with a hand-drawn look to 3D objects. By using it along with "PSOFT Pencil+ 4 Render App", the high quality lines adopted by many anime productions can easily be used.

High-quality lines

Create a wide range of richly expressive lines such as mechanically uniform lines, lines jutting out of objects for a rough sketch look, or lines with ample width modulation like those found in Japanese manga. Handle any scene with detailed settings to specify where to draw lines, such as drawing on objects' mutual intersections, on material boundaries, on hidden lines on the back of objects and more.

Vector File Output

Lines can also be output in EPS/PLD formats.

EPS format is a resolution-independent vector graphics file. It is recommended for visualization purposes in fields such as architecture, manufacturing, product design, web content, and interactive application interfaces.

PLD format is a dedicated data format for editing lines in "Pencil+ 4 Line for After Effects". It allows you to adjust line colors and textures within After Effects.

Sharing Pencil+ settings

Compatible with the "Pencil+ 4 Bridge" utility

The free "Pencil+ 4 Bridge for 3ds Max / Maya / Unity / Blender" is an extension utility for Pencil+ 4 used to transfer Pencil+ 4 Line and Pencil+ 4 Material settings between Blender and 3ds Max, Maya, and Unity. The data is managed as a file separate from the scene file, so it can easily be applied to other scenes. This promotes collaboration between artists using different software, and improves the flexibility and efficiency of projects.

Notes:
With Unity, only Pencil+ 4 Line settings can be transferred.
Mutual import of settings may be limited due to differences in Pencil+ functionality between each platform.
Rendering results may vary depending on the renderer's algorithm.
Parameters that are not compatible between various Pencil+ 4 products cannot be included.
Output and input of Pencil+ 4 Material settings are supported with Pencil+ 4 Bridge for Blender version 4.0.1 and later.

Development Collaboration

We received comments about the development of the plugin from khara, Inc.
Comments by: CGI director / Daisuke Onitsuka

*The comments were made in January 2023 during the Beta version phase.

Why was Pencil+ necessary for Blender?

Onitsuka: Even at the standard level, there are various line drawing functions in Blender, but after various tests, we found that there was nothing that matched the speed and quality of Pencil+.
Also, our company had a lot of past data made with Pencil+ and we needed to reuse that data.
Therefore, we thought that if Pencil+ was available for Blender, it could help not only our company, but people in the whole industry transfer to Blender, so that's how we came to discuss the development of the plugin.

What was your impression after using the plugin?

Onitsuka: Since it became possible to check the line drawing in the Viewport, which was not implemented in the MAX version, we were able to greatly reduce the amount of line settings mistakes. Being able to check line thickness before rendering is extremely useful.
Also, the ability to transfer line settings between MAX, MAYA and Blender using Pencil+ 4 Bridge is very attractive.
The functionality related to line settings available in the MAX version is almost completely implemented, so there is no gap with regards to quality.

Please tell us about your outlook for the future.

Onitsuka: Our company is in the process of making a complete transition to Blender, so productions that will be announced from now on will be created using Blender.
While collaborating on the development of Pencil+ for Blender, we already adopted it for a number of productions, so please look forward to our announcements.
