The drop-down selection shows the name of the currently active variation, and lets you switch between the variations available in the project. If you have made changes in the current variation and select another one, then you will get asked if you want to save the current variation.
Create a new variation. You can select to make the new variation a copy of one of the existing ones, or start with a default variation setup. If you have made changes to the current variation, then you will get asked if you want to save it first.
The drop-down selection shows the name of the sky definition currently assigned to the current variation, and allows to assign a different one.
Create a new sky definition. You can select to make the new sky definition a copy of one of the existing ones, or start with a default sky definition setup. If you have edited the current sky definition, then you will get asked if you want to save it first.
Change the parameters of the currenly selected sky definition.
Notice: Sky definitions are global to the project. This means that if you edit a sky definition within the current variation and there are any other variations in the project that use the same sky definition, then future simulations in the affected variations will all use the new settings.
The dialog manages the geometry objects in the current variation. You can add and remove objects, set object specific simulation settings and assign materials, patterns, textures and mixtures. Notice: Material, pattern, texture and mixture definitions are global to the project. This means that any changes made to this data will have effect for all objects in other variations that have the same modifiers assigned to them in future simulations.
Set Render Parameters...
Simulation settings are defined by setting qualitative requirements for the variation and its output. For further refinement, more detailed parameters can be set to override the values determined from the qualitative requirements.
Set Mkillum Parameters...
The option is only active if any objects in the variation are set up to be converted to secondary sources. This precalculation process requires its own set of simulation settings.
Set Special Parameters...
Chose default values for the treatment of participating media (without effect if none are used in the variation). Control the amount and frequency of logfile entries.
