Less sub-triangles mean less detail, faster rendering and less RAM. More sub-triangles mean more detail in the displacement, slower rendering times and more RAM usage. Note that each triangle of the original mesh is divided into sub-triangles. The behavior of this parameter depends on the View Dependent parameter above. When disabled, the Edge Length value is the maximum sub-triangle edge length in world units.Įdge Length – Determines the quality of the displacement. A value of 1.0, for example, means that the longest edge of the resulting mesh will be about 1 pixel long (when projected on the screen). View Dependent – When enabled, the Edge Length parameter determines the maximum length of a sub-triangle edge, in pixels. Use it when you get splits (usually around sharp edges) in the displaced geometry. Keep Continuity – When enabled, V-Ray tries to produce a connected surface. This value can be either positive or negative. Shift – Specifies a constant which will be added to the displacement map values, effectively shifting the displaced surface up and down along the normals. This value can also be negative, in which case the displacement pushes geometry inside the object. Higher values produce a greater displacement effect. A value of 0.0 means the object appears unchanged. You cannot use this method for 3D procedural textures or other textures that use object or world coordinates.Īmount – Specifies the amount of displacement. However, it requires that the object has valid UV coordinates. The advantage of this method is that it preserves all the details in the displacement map. The actual raytracing of the displaced surface is done in texture space, and the result is mapped back into 3D space. The displaced surface is rendered as a warped height-field based on that texture map. 2D Displacement – Bases the displacement on a texture map that is known in advance. Normal Displacement – Takes the original surface geometry and subdivides its triangles into smaller sub-triangles which are then displaced. Mode/Map – Specifies the mode in which the displacement is rendered:
