Dear friends and fellow Blenderheads, could you give me a hand with that profile? I have curve with a bevel profile - basically a lofted cornice. And it should have a cover on top. Is there a possibility to still have it as a curve without converting to mesh and have 2 materials assigned to it. E.g. material 1 - white stucco and material 2 - metal plate? Thanks.

There is currently no way to have multiple materials using a single curve and a profile object.



You could have a single material containing 2 different shaders, but you would need a way to separate what material is for what part of the object. One way to do that would be to use a bevel object curve composed of two separate splines inside. You could flip the direction of one of the splines (w -> Switch Direction with the spline selected in edit mode) in order for the result to have one part of it with inverted normals.



enter image description here



You could then use Backfacing output of the Geometry node to mix your different shaders. Note that you will have the normals inverted so you will also have to take that into account in one of your shaders: for example you would have to invert the IOR value of the Fresnel node if you used one in the shader:

Confectionery

Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
