- Bugfix: TwinfinityApiClient.getChanges() now works as expected when called with a non BimContainer change.
- * It is now possible to use BimContainer as argument to LayerApi.getOrLoadLayer() in the @twinfinity/core package. * Layers now use the following url convention /_layer. Example: /sites/portal/projects/hellotwinfinityworld/_layer.assets, denotes a assets layer on the hellotwinfinityworld container. * Exceptions reported through telemetry.trackException are now logged with console.error() so the exception stack trace is retained in the output.
- Added option to cull expensive meshes when moving the camera therefore increasing performance. Which meshes should be culled can be controlled by a predicate passed to the geometry builder or left undefined and it will be handled by a default predicate.
