Introducing Hololight Stream (formerly ISAR SDK) New Features, Enhancements, and Bug Fixes

We’re excited to announce the release of Hololight Stream, which is now available on Hololight’s GitHub profile. This update brings several new features, enhancements, and bug fixes based on valuable user feedback and our product roadmap. In this blog post, we’ll provide a comprehensive overview of what’s new in this release.

New Features in Hololight Stream 

Spatial Anchor System 

Introducing Spatial Anchors, a powerful system designed for aligning augmented content with the real world. These anchors can be saved and reloaded, ensuring a seamless user experience and persistent content placement. 

Configurable Signaling Port 

For increased flexibility, we’ve introduced the ability to set any non-reserved port between 1024 and 65535 for establishing the connection between the Server and Client, instead of the default port 9999. 

Client Device Camera Settings 

We’ve added the ability for users to change camera-related settings, such as resolution, framerate, and exposure, at runtime. This feature allows for better customization and control of the mixed reality experience. 

Watermark for Trial Version 

The time-based expiration of the Hololight Stream Trial version has been replaced with a watermark displayed at regular short intervals, providing a more transparent and consistent trial experience. 

Bug Fixes in Hololight Stream 

We’re committed to continuously improving Hololight Stream, and that includes fixing bugs. Based on feedback from users, partners, and internal developers, we’ve addressed the following issues: 

Distortion with Depth Enabled 

We’ve fixed an issue where objects and menus would distort when Depth was enabled for Hololight Stream, especially noticeable when objects were close to the user. 

Missing Hololight Stream Rendering Preset Window 

The missing Hololight Stream Rendering preset window when clicking on “Rendering” preset has been fixed. 

Outline Around Objects with Depth Enabled 

We’ve fixed an issue where enabling Depth caused an outline around objects to be displayed in the camera’s solid color.  


Hololight Stream brings exciting new features and enhancements that aim to improve your mixed reality experience. Please note that the Android client and Depth Alpha feature are still in BETA, so keep that in mind while using these features. 

We appreciate the feedback from our users and partners, and we’re committed to refining our product based on your input. Be sure to give the new Hololight Stream a try and let us know your thoughts via our feedback and support portal. Happy developing!
