So you have an Unreal 3D project uploaded to the PureWeb Reality Platform and streaming in your customized web client, but the stream doesn't fill the entire available space of the browser window.
There are two reasons why the stream doesn't adjust to the browser viewport's size:
- The 3D model has a fixed resolution and aspect ratio built in that overrides what is requested by the web client.
- The built and submitted 3D project doesn't have the PureWeb plugin included, which takes care of this adjustment on browser resize. Pixel Streaming may still work without the plugin, but the resize will not.
Follow the Preparing your Unreal Project guide to add the plugin.
