Known Issues / Behaviors
Undo in Blender
If you use the Undo in Blender whilst in a lighting session with HDR Light Studio, then this can really mess things up. So please use the Undo inside HDR Light Studio instead to undo your lighting changes.
For example: If HDR Light Studio is open, and you use Undo in Blender, and then export the Blender scene into HDR Light Studio using the re-sync button, it will crash Blender.
Screen based reflections in Eevee
If an area light front face is not visible in the view, it will not show in reflections when using Eevee. This is how Eevee screen based reflections work at the moment.
Export Limiations of Scenes into HDR Light Studio
We use Blender's Alembic exporter to send scenes into HDR Light Studio's Render View.
Currently we have noticed that these features are not exporting using this exchange format:
1) Instanced Geometry
2) Solidify Modifiers
3) Particle Systems
