The production of shadows in solidThinking can be controlled for each object in the scene, as well as for each light.
All objects will cast and receive shadows when illuminated by lights which have the shadows enabled (note that by default shadows are disabled).
However, there may be situations where this is undesirable, for instance, certain objects cannot produce a visible shadow, due to the viewing position: excluding these objects from shadow calculations can result in improved rendering performance; both in terms of increased speed and reduced memory usage.
This can be performed very easily through the World browser (in case the panel is not displayed, you can open it by choosing Managers > Browser). By right clicking one or more selected objects in the browser, a popup menu appears allowing you to instruct the program as whether an object must Cast shadows or not and whether it must Receive shadows or not.
You can resort to these options also to illuminate certain areas of a scene without creating shadows, without the need for a complex system of ‘fill’ lights as would be used in a theatre or movie set.
