In IsaacSIM 2023.1.1 we are trying to use Sunstudy (v1.0.11) in headless for our simulation, therefore we are not using the GUI to configure the sky, but instead passing the settings programatically (date, time, latitude, longitude and DeclinationFromDayOfYear). By doing so we are getting a very strange behavior of the sky, it seems as if any change to the values is not being updated properly unless there is some interaction with the GUI (which does not work for us, since we are doing this headless)
As a work around we are currently making some tests by passing the settings via Replicator, but when trying to set the property “inputs:DeclinationFromDayOfYear” we get an error:
2024-08-15 15:12:10 [Error] [omni.graph.core.plugin] /Replicator/SDGPipeline/OgnWritePrimAttribute_05: [/Replicator/SDGPipeline] OmniGraph Error: Attribute ‘inputs:DeclinationFromDayOfYear’ could not be found for prim at /Replicator/Ref_Xform/Ref/Looks/SkyMaterial/Shader.
