See an animated screenshot comparison by clicking this link: Obl_ShadowFilter.gif (556KB) - pay close attention to the outlines of the horse's shadow at each setting. Shadow Filtering: This is a very important setting if you have enabled any of the shadow-related options above. As always, the quality and hence the performance impact of the shadows cast depend on the Shadow Filtering option below. While adding to the richness of atmosphere in forested areas, it can also noticeably reduce performance outdoors. The screenshot comparison above demonstrates the difference.
Tree Canopy Shadows: This setting controls whether trees cast realistic shadows on the surrounding objects/ground around them. There is also a noticeable performance impact, so on balance I recommend disabling Self Shadows both to boost performance and also to remove potential visual glitches. The quality of the shadows cast depends on the Shadow Filtering setting (see below), however even at High quality, the shadows may be unrealistic and have funny edges to them - at times. With it set to Off, the character still has some shadows on her face. See the screenshot comparison above, and note that with Self Shadows enabled (left image), the character's head casts a shadow on the body, and her face has additional shadows. Importantly, this setting does not affect whether characters cast shadows on the ground, only on themselves. That is, depending on the position of the local lighting relative to their body, characters will cast accurate shadows on themselves based on the contour of their body, faces, clothing and worn items in relation to the strongest light source.
Self Shadows: If set to On, this option allows characters to cast shadows on themselves.
