Is it possible to save rendered shadows and then render the scene without rerendering shadows using the prepared ones?
Preparing shadows is a common practice in WB. Generally, you have to make two render passes in order for your scene to display them. • Make sure that “generate first frame” is set for shadows in all light sources. • Render the scene. Note that the “Generate Map” radio will automatically change to “Generate Never”. • You can now render you scene as many times as you want without recalculating shadows.
