Uniform knot spacing makes the profile curves run parallel to the V direction. NURBS > Loft > Parameterization This modifies the parameterization of the lofted surface (see Parameterization of NURBS curves and surfaces ). Increase it for faster rendering and less RAM usage, but lower quality. Skins a surface along a series of profile curves. Also if you want to lower the quality of the NURBS surfaces, it is better to do this by increasing the Curvature threshold parameter, rather than lowering this one.Ĭurvature threshold – Decrease this parameter to allow V-Ray to subdivide the NURBS surface more, for a smoother result. Note that this number is proportional to the logarithm of the actual number of triangles, so you don't need very high values. Max tessellation depth – This parameter controls the maximum number of triangles that V-Ray is allowed to generate for this NURBS surface. This saves memory for other purposes, but may be slower. When off, NURBS surfaces are treated as dynamic geometry, similar to Subdivision meshes, and are converted into triangles on the fly. import maya. This allows the building of a faster intersection structure, but takes more memory.

Generate static geometry – When enabled, V-Ray subdivides the NURBS surface into triangles before the actual rendering has begun.
