| - | ====== 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. | ||
| - | |||
| - | 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]]. | ||

| - | **Activate:** This check box is a toggle to enable and disable Transmission via an imported mesh. A mesh must be loaded in the 3d Preview to use this feature. | ||
| - | |||
| - | **Attenuation:** A toggle between the Ramp Linear and Exponential Decay attenuation types. | ||
| - | |||
| - | **Scale:** Changes the scale of the distances before mapping it to a transmission value. | ||
| - | |||
| - | **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. | ||
| - | |||
| - | **Bias:** A bias value based upon mesh density. A value of 10 should be good for most situations. | ||
| - | |||
| - | |||
| - | |||
| - | Knald will automatically cap open meshes before rendering which in addition to producing more visially pleasing results, negates the need for any sort of major cleanup via image editing. | ||
