Features:
• Volumetric Fog shadows.
• Physically based.
• Supports fully dynamic scenes & lightning.
• 3 different filters to counter aliasing.
• Produces soft results, which fits current generation art style of the games.
• Height & ramp settings to control fog distribution.
• Sun and atmosphere phase functions for all kinds of atmosphere effects.
• Volumetric fog can be extended by analytical fog to cover large view distance, where volumetric fog would produce artifacts.
• Spot and Point light support (not shadowed).
• User specified volumes to generate custom fog areas.
• Culling to support large amount of lights and volumes per scene.
• Realistic volumetric clouds with many options to play with.
Specifications:
• Supports all rendering paths.
• Support for cascaded shadow mapping, both stable and close fit projections.
• Many different quality settings for both low & high end devices.
• Multiple customization options to match any environment you might have.
