 Enhancing Game “Visuals” and “Ease of Creation”
Major Update Ver. 2.4 Released
 SmileBoom Golden Week Sale 2026 Also Now Live!

April 27, 2026 - Sapporo, Japan – SmileBoom Co.Ltd. today released the major update Ver. 2.4 for “RPG Developer Bakin” (read as "BAH-keen"; hereafter referred to as Bakin). This update introduces enhanced visual features, including the implementation of shadow maps, as well as new functions designed to streamline event creation. In addition, the company has revealed plans for future feature expansions, including support for “Live2D,” a service provided by Live2D Inc.
Furthermore, the “SmileBoom Golden Week Sale 2026” is now underway, offering the base version of Bakin and various DLC at special discounted prices.

Major Update Ver. 2.4 Enhances Visuals and Development Efficiency

Ver. 2.4 significantly enhances visual capabilities, starting with the implementation of shadow maps, enabling more immersive and visually rich gameplay. In addition, new features—such as an event panel that supports multi-branching based on variable values—allow developers to construct complex processes more simply, greatly improving development efficiency.

Various other features have also been added and refined to support game creation, making the experience more comfortable and enjoyable for both beginners and advanced users.

● RPG Developer Bakin Ver. 2.4 New Features Overview

■ Shadow Maps

A new “Shadow Map” feature has been implemented, allowing shadows to be automatically generated based on lights placed within a map with a simple toggle. This makes it easy to incorporate immersive lighting effects—such as shadows cast by campfires or flashlights—into your game.

■ Camera Z Rotation

The camera Z-axis rotation (roll) feature has been added. By intentionally tilting the screen, developers can create unsettling horror scenes or impactful cutscenes, enabling more impactful and memorable visual presentations.

■LOD（Level of Detail）

A feature has been introduced to switch between LOD models embedded within models, based on their displayed height relative to the screen. By simplifying models that are farther from the camera, this helps reduce processing load and improve performance.

■ “Multi-branch (by Variable Value)” Panel

A new panel allows multiple branching paths based on variable values. Similar to a switch statement, it supports branching not only by numerical values but also by strings. This simplifies conditional branching that previously required combining multiple event panels.

 

In addition, numerous other features and improvements have been implemented, including a function to search for where common events are used, cloud shadows as a post-effect, and the introduction of parallax mapping.

Take this opportunity to challenge yourself and create your own games with RPG Developer Bakin!

Future Update Plans (Roadmap)

Bakin has published a roadmap for upcoming feature expansions on its official website and plans to continue delivering regular updates. Development is currently underway to further enhance expressive capabilities and the overall creation experience. As part of this initiative, support for “Live2D,” provided by Live2D Inc., is planned.

Stay tuned for future developments.
