Current version: 2.12.6

Release Date	Version	Release Note / Changelogs
02/24/2025	2.12.6	Major Improvements (vs 2.11.1) for converted models Up to 60% less draw calls Up to 33% less total textures Up to 32% less total materials Up to 12% less average memory used Updates Super Texture Atlas Merging: Texture data can now be merged into super texture atlases, minimizing draw calls coming from several separated small textures in a 3D model enables the data to be more efficient for streaming. Lightmap Support: Lightmaps are now being supported via a separated file. 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. Improved Update Logic: 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. Performance Improvements: 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. Bug fixes Compatibility Dependencies Requires PlayCanvas Plugin version 2.5.1 or higher Requires Unity Plugin version 2.7.3 or higher
01/13/2025	2.11.1	Major Improvements (vs 2.9.8) for converted models Up to 30% less draw calls Up to 30% less memory for textures used Up to 49% smaller converted file sizes Up to 67% less total memory used Updates Improved Decimation Algorithm: Able to automatically configure the best possible algorithm when creating LODs with as little visual quality loss as possible. Shared Materials Feature: 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. Remove the need for Baked Textures: Drastic reduction on memory needed for textures, bringing an important gain on overall performance. Bug fixes Compatibility Dependencies Requires PlayCanvas Plugin version 2.5.0 or higher Requires Unity Plugin version 2.7.1 or higher
10/28/2024	2.9.8	Updates Bug fixes and minor performance updates Compatibility Dependencies Requires PlayCanvas Plugin version 2.5.0 or higher Requires Unity Plugin version 2.5.0 or higher Requires Unreal Engine Plugin version 2.0.2 or higher
