I contribute in the developement of the exporter for LuxCoreRenderer and when I try to read the data of a smoke simulation, the length of the data arrays are empty.
len(mod.domain_settings.density_grid) returns 0 even when the simulation has been baked and the smoke is visible in the viewport. @brecht Is this a bug or how can the data be accessed in Blender 2.8?
Are you reading the data from the evaluated object?
As far as I know the volume grid data should exist in the objects you get from iterating over the objects and instances in the dependency graph.
thanks for the quick response. With the evaluate object it returns the correct data. Thanks for the help.
