DisplacementThe process of utilizing a 2D texture map to generate 3D surface relief. As opposed to bump and normal mapping, Displacement mapping does not only provide the illusion of depth but it effectively displaces the actual geometric position of points over the textured surface. mapping utilizes a 2D texture map in order to generate 3D surface relief. As opposed to Bump and Normal mapping, Displacement mapping not only provides the illusion of depth, but it also displaces point positions over the surface based on light and dark values of the Displacement texture. The OctaneRender® Displacement node controls how the texture displaces the surface. Displacement mapping requires a UV projection for the object with the displacement. Models created in other 3D applications (ZBrush®, Mudbox®, Maya®, etc.) need UV texture coordinates, and the Displacement map texture should match the model's UV layout. Procedural textures will not work for Displacement in OctaneRender - only Image textures will work, thus, procedural textures will need to be baked prior using a Baking Texture.


You can find the Displacement node by right-clicking in the Nodegraph Editor and navigating to the Displacement category (Figure 1).


Note: Motion BlurAn optical phenomenon that occurs when a camera’s shutter opens and closes too slowly to capture movement without recording a blurring of the subject. with Displacement is currently not supported.
