******* Shading ******* Globally de/activates engine features in :menuselection:`Render --> Shading` panel... Texture All :doc:`/render/blender_render/textures/properties/influence/index` e.g. color, but also normal and displacement maps. Shadows All :doc:`/render/blender_render/lighting/shadows/index` calculation. Subsurface Scattering All :doc:`/render/blender_render/materials/properties/subsurface_scattering`. Environment Map The :ref:`world texture `. Ray Tracing The :doc:`shadow tracing `. Alpha Switches between a world background to be the sky or transparent. Sky, Transparency World Space Shading Shading can optionally be computed in world space rather than camera space. This affects e.g. normal and lamp vectors. This is often more convenient and matches other engines behavior.
