Importing Scene Geometry
On rare occasions, when you press the play button in HDR Light Studio on Render View [HDR Light Studio], the Houdini scene might not sync with HDR Light Studio. To fix this, users can click inside the HDR Light Studio connection panel in Houdini and the scene will sync.
Currently, area lights under Octane do not show correctly due to a bug - we are waiting for OTOY to fix this. HDR Light Studio plug-in sets the “Use Alpha” check box in the Distribution-IES Texture panel of the Shader settings in the area light properties, but now when this is set, you will not see the light. The workaround is to uncheck this tick box. However, that means you will have no alpha on your area light.
When IPR Running, if you make an area light in HDR Light Studio (Arnold mesh light) and put a texture on it, it's shown as white with no texture. The IPR needs to be restarted before it’s picked up by Arnold. This is an Arnold bug.
If the IPR completes - changing the light textures will not invalidate and restart the IPR rendering.
