1.8x Change Logs

1.80.5 (June 17, 2026)

C++ / Runtime

  • Fixed renderer vertex buffer ring handling to prevent vertex buffers from growing unnecessarily and causing a memory leak.

1.80.4 (June 13, 2026)

C++ / Runtime

  • Updated LLGI and fixed rendering issues including GPU particle ComputeBuffer updates, UV2, and matrix calculations.

  • Added WebGPU support for premultiplied alpha.

  • Fixed DX9 model rendering vertex layouts, render state restoration after instanced drawing, and material shader processing.

  • Fixed vector comparison expression conversion in the Metal material compiler.

  • Added support for RG11B10_UFLOAT texture format.

  • Fixed soft particle and material shader background handling.

  • Fixed F-curve interpolation on the final segment.

  • Fixed a bug where Directional Billboard did not face the correct direction on the initial frame or after seeking.

  • Fixed a bug where infinite UV animation frames were not cached correctly for trails.

  • Normalized Light Curl Noise vectors to improve noise stability.

  • Fixed a possible out-of-bounds read with malformed GLTF matrix input.

  • Fixed WebAssembly SIMD and multithreaded environment settings.

Tool

  • Added support for renaming nodes directly in the Node Tree.

  • Fixed a bug where the random seed was unnecessarily updated when seeking backward in the editor.

  • Stopped viewer initialization when renderer initialization fails, preventing invalid renderer references from remaining.

  • Improved material editor launch diagnostics by showing an error dialog and writing logs when launch fails.

  • Relaxed the path length limit for paths sent to the material editor and improved logging when long paths cannot be opened.

  • Adjusted saved window positions at startup when they are outside the visible display area.

  • Fixed depth handling for line rendering used by guides and related views.

  • Fixed icon display issues.

Build

  • Changed Linux packages to be built in a glibc 2.28 environment.

  • Fixed build settings for tests and screenshot tools in older GCC environments.

  • Expanded the screenshot comparison tool and rendering backend regression tests.

Unity

  • Updated EffekseerForUnity to 1.80.4.

  • Updated the bundled Effekseer to the 1.80.4 equivalent and reflected the core fixes in the Unity plugin.

  • Fixed the Depth Texture access flag in URP (RenderGraph), so rendering paths that read Depth Texture work correctly.

1.80.3 (May 17, 2026)

C++ / Runtime

  • Fixed rendering issues related to DX9, Vulkan, Metal, WebGPU, and LLGI.

  • Fixed GPU particle rendering shaders.

  • Fixed a bug where disabled UV distortion affected Advanced Render UV distortion.

  • Fixed SIMD bugs.

  • Fixed a bug where the Not Equal comparison node returned an incorrect result.

Tool

  • Added Russian language support.

  • Improved gradient editing in the material editor and fixed related bugs.

  • Fixed font scaling in high-DPI environments.

  • Fixed window size and placement issues when maximized.

  • Fixed Node Tree display and operation issues.

Build

  • Added macOS arm64 output support.

  • Fixed package dependencies and build settings.

Unity

  • Updated EffekseerForUnity to 1.80.3.

  • Fixed compiler settings for Android and WebGL.

  • Improved error logs during material import.

  • Fixed .efkmat handling for texture slots, uniform counts, gradients, and custom data.

  • Fixed issues where mirror wrapping, time, lighting, refraction, and custom data were not applied correctly in Unity Renderer.

  • Fixed incorrect animation frame selection for models.

  • Fixed a bug where Blend UV Distortion was not passed correctly.

  • Fixed temporary RenderTexture destruction in the editor.
