8.1 Truelight Materials· Repeat Mode UV: Sets the repeat mode of the texture. There are fourmodes, which can be set:· Repeat: Repeats the texture in all directions.· Mirrored Repeat: Repeats and mirrors the texture on the x- and y-axis with every repetition.· Decal: The texture will not be repeated.· Clamp: Repeats only the last pixel of the texture will be repeated.· Link repeat modes: Uses the same repeat mode for v-coordinates as forthe u-coordinates.· Repeat UV: Sets the number of repetitions for the Uvs.· Offset UV: Sets the offset for the UVs.· Rotate: Rotates the UVs.· Anisotropy: Sets the texture filter quality for the image texture. 1 is thelowest quality. 16 is the highest quality.» Displacement Displacement maps are detailed maps, which are interpreted asheight information. Using displacement maps you can create highly detailed structuresfrom rather simple geometry by just using a plain image. Each point onthe geometry is displaced along the interpolated vertex normals using the heightinformation of the map, resulting in a realistic silhouette and producing correctshadows and reflections. Accuracy is only limited by the resolution of the textureimage and memory requirements are very low. To avoid cracks in the displacedsurfaces the vertex normals should be smooth and consistent. Using a highertesselated bases mesh can improve performance a lot.» Displacement Height: Defines the height of the displacement.» Use Accurate Silhouettes in OpenGL: Off by default, this feature allows to calculatethe displacement in OpenGL like in raytracing mode. Turning it on maydrastically reduce the performance.173
