<table><thead><tr><th width="139">Release Date</th><th width="82">Version</th><th>Release Note / Changelogs</th></tr></thead><tbody><tr><td>11/20/2025</td><td>3.1.2</td><td><p><strong>Updates</strong><br></p><ul><li>Mini Textures: Mini textures are now implemented for faster initial loading, loading first a lower resolution texture for the 3D models, which improves over time.</li><li>Updated Presets: Updated presets for conversion, the presets are now presented as Performance, Balanced, Quality and Ultra.</li><li>Ultra Quality Preset: Ultra quality preset is now implemented, providing conversion using PNG textures instead of using KTX image compression, for ultra quality. This is recommended only for single model display, since PNG can display high visual quality, however with a serious hit on performance.</li></ul></td></tr><tr><td>08/06/2025</td><td>3.0.2</td><td><p><strong>Improvements (vs 2.12.10) for converted models</strong></p><ul><li>Up to 12% increase in total mesh count</li></ul><p><strong>Updates</strong></p><ul><li><strong>Animated Models Support</strong>: Animated .GLB format models with animation using rigging, bones, weights, skinned and transforms animations are now supported.</li><li>Note: Vertex animation or morph targets are not currently supported</li><li><strong>Texture and Material Improvements:</strong> Texture baking now picks the best sample type automatically. Texture wrapping and texture sampler properties are now supported.</li><li><strong>Export &#x26; Compression Enhancements:</strong> Improved node hierarchy structure and internal storage structure for more efficient data handling</li><li>Bug Fixes</li></ul><p><strong>Compatibility Dependencies</strong><br>Requires PlayCanvas Plugin version 2.6.2 or higher<br>Requires Unity Plugin version 3.0.0 or higher</p></td></tr><tr><td>06/12/2025</td><td>2.12.10</td><td><p><strong>Major Improvements (vs 2.12.6) for converted models</strong></p><ul><li>Up to 9% smaller converted file sizes</li><li>Up to 29% less draw calls</li><li>Up to 38% less total textures</li><li>Up to 46% less total materials</li><li>Up to 13% less average memory used</li></ul><p><strong>Updates</strong></p><ul><li><strong>[Fixed]</strong> Normal map issue on some mobile and desktop devices

You can now upload a ZIP file containing your .GLB model and a file called “lightmap.hdr” or “lightmap.png” - this lightmap will be automatically applied to the Streaming Model inside PlayCanvas Engine running with VIVERSE Create SDK. Currently only one lightmap is supported.</li><li><strong>Improved Update Logic:</strong> With the use of Virtual Bounding Boxes, the update logic is now improved to calculate distances more accurately according to the actual visible mesh geometry in the scene. The camera frustum is also improved with a perspective bias update logic, making what the user is actually seeing more important and prioritized during streaming.  </li><li><strong>Performance Improvements:</strong> Several improvements and modifications regarding performance, such as Material Merging and Super Texture Atlas. Large environment scenes will see bigger improvements with minimized draw calls usage and optimized VRAM usage.</li><li>Bug fixes</li></ul><p><strong>Compatibility Dependencies</strong><br>Requires PlayCanvas Plugin version 2.5.1 or higher<br>Requires Unity Plugin version 2.7.3 or higher</p></td></tr><tr><td>01/13/2025</td><td>2.11.1</td><td><p><strong>Major Improvements (vs 2.9.8) for converted models</strong></p><ul><li>Up to 30% less draw calls</li><li>Up to 30% less memory for textures used</li><li>Up to 49% smaller converted file sizes</li><li>Up to 67% less total memory used</li></ul><p><strong>Updates</strong></p><ul><li><strong>Improved Decimation Algorithm:</strong>  Able to automatically configure the best possible algorithm when creating LODs with as little visual quality loss as possible. </li><li><strong>Shared Materials Feature:</strong> The system is now able to look-up materials being used, combine compatible texture-less materials and remove duplicates from a streaming model. This  optimizes the usage of texture-less materials and minimizes the amount of draw calls created by duplicates or the use of several similar materials in a model. </li><li><strong>Remove the need for Baked Textures:</strong>  Drastic reduction on memory needed for textures, bringing an important gain on overall performance.</li><li>Bug fixes</li></ul><p><strong>Compatibility Dependencies</strong><br>Requires PlayCanvas Plugin version 2.5.0 or higher<br>Requires Unity Plugin version 2.7.1 or higher</p></td></tr><tr><td>10/28/2024</td><td>2.9.8</td><td><p><strong>Updates</strong></p><ul><li>Bug fixes and minor performance updates</li></ul><p><strong>Compatibility Dependencies</strong><br>Requires PlayCanvas Plugin version 2.5.0 or higher<br>Requires Unity Plugin version 2.5.0 or higher<br>Requires Unreal Engine Plugin version 2.0.2 or higher</p></td></tr></tbody></table>
