O 6 Copy the new Library File from the Kerkythea Materials Libraries folder into the Twilight Materials folder a ad ae DISADVANTAGES TO REMEMBER WHEN USING LIBRARIES In the setting of an office or network when sharing a scene the library must also be sent with the file Library materials are dumb materials that is they can not be easily edited Edge Lines do not work with Library Materials unless they are created specifically to do so Materials can of course be exported via xml to Kerkythea edited and saved into a library again etc Faceted Geometry of Curved Surfaces K If there is a curved surface that should be rendering smooth but it renders as faceted place the geometry within a group or component and it should render smooth HDR High Dynamic Range HDR images contain 32 bits of information per pixel as opposed to 8 bits with a jpg In rendering one typically uses a spherically mapped HDR image to actually project light onto a 3D scene from all directions at once In this manner if an HDR is created in a specific place St John s Cathedral for example and then used to light a 3D object one should be theoretically able to visualize the object as if it were lit with the exact light that it would get in St John s Cathedral There are thousands of HDR images available for download via many different websites HDR typically provide all the light your scene needs Exceptions would be in the case of using HDR i

Weld vertices BP p 70 3 Welding vertices means you want to find all pairs of vertices with po i bag i N distance of each other and join them into one A normal is an imaginary line drawn perpendicularly out from the front of a face It is used to decide which edge between two faces should appear smooth and which should appear as a crease or sharp This only comes into play when weld vertices is chosen This is important also with the rendering of Edge Lines correctly on curving surfaces because the vertices of a model for materials on curving surfaces will need to be welded and this reguires that a hard edge angle chosen 30 is a good angle to choose to start as _ the smooth angle in most cases with default SketchUp curves Combine Hard Edge Angle with Edge Lines when working with Edge lines on curved surfaces if not the edge lines will show on each facet of the curved surface Edge Line Checking the Edge Lines box will render lines similar to the edge lines you see in the SketchUp view Edge Line thickness in Twilight is not linked to edge line sizes in SketchUp To define edge lines use a simple rule of thumb Lonely Edges can not be rendered That is an edge that does not define the edge of a face will not be processed by Twilight To render a Lonely Edge simply make it into a face by using a free ruby plugin for SketchUp such as Extrude Lines 2 Points rb which may be found at the Ruby Library D
