# Render Geo Settings ## Dicing - Like renderman micro polygon length ### Dicing quality - This parameter controls the geometric subdivision resolution for smooth surfaces (subdivision surfaces and displaced surfaces) - A higher value will generate smaller micropolygons meaning that more shading will occur - but the quality will be higher. - The distance to camera, would be closer = increase, farther away = decrease relative to your settings. ### Dicing minimum - When not set to -1, karma will set minimum number of rows and columns on each face to be 2 to the power of this value when dicing for subdivision or displacement. ### Dicing Maximum - When not set to -1, karma will set maximum number of rows and columns on each face to be 2 to the power of this value when dicing for subdivision or displacement. Setting the same (or lower) value as “Dicing Minimum Depth” is effectively equivalent to fixed parametric subdivision that ignores raster space/offscreen measurement. Recommended leaving this value at -1. - ## Displacement ### True displacement - This setting controls how the displacement shader on the object will be run. - **Bump Mapped Displacement** - The displacement shader is run, but only modifies the surface normal. This does not dice geometry and can save memory. - **True Displacement** - The geometry is diced and displaced. This will cause proper silhouettes and shadowing of displaced surfaces. - **Disable Displacement Shader** - Disable the displacement shader entirely. There will be no bump mapping or displaced geometry.
