 ====== Transmission Maps ======
+Designed to be used as omni-directional thickness map (with an attenuation ramp) for semi-translucent materials, Transmission are generated in much the same way as our high quality [[ambient_occlusion_maps_knald|Ambient Occlusion]] solution & it’s just as fast. Simply load a mesh into Knald (multi-million polygonal meshes are supported), check a box and then watch Knald do its magic.

Simply load a mesh into Knald (multi-million polygonal meshes are supported), check a box and then watch Knald do its magic.
 After only a couple of seconds you will be greeted by your new and beautiful texture which is viewable with real-time translucency in the 3d preview window.
+You can also generate Ambient Occlusion from high to low polygonal meshes via [[the_baker_knald|The Baker]].

-Ramp:Ramps the light and dark values within the Transmission map based upon the sliders value.
-Rays: This slider is used to determine the number of samples in a discrete evaluation of the integral across the half sphere for diffuse outgoing radiance with a constant radiance field, with a minimum of 256 and maximum of 8192 rays being available. A higher number or rays will increase the quality of the Transmission at the cost of speed. We do not recommend going below a value of 512 rays as this can cause banding to appear in the map. A value of 1024-2048 or above should be perfect for production.
