Sampler drop-down list Lets you choose which supersampling method to apply. The list is not active unless Use Global Settings is turned off. Default=Max 2.5 Star. Supersample Maps When on, the maps applied to the material are supersampled as well. When off, the supersampler uses pixel averages for maps. This switch is active only when Use Global Settings is turned off. Default=on. Quality Adjusts the quality of supersampling by controlling the number of samples used for each pixel. At the minimum value, 0.0, four samples are taken per pixel. At the maximum value, 1.0, about 40 samples are taken per pixel (the value varies depending on which shader is active). Range=0.0 to 1.0. Default=0.5. This spinner is unavailable for the Max 2.5 Star method. Adaptive Visible only for the Adaptive Halton and Adaptive Uniform methods. When on, these methods take fewer samples than the Quality specifies unless samples show a change in color greater than the Threshold value. In that case, they take all the samples specified by the Quality. Turning on Adaptive On can reduce the amount of time required to supersample. Default=on. Threshold Controls the Adaptive methods. Visible only for the Adaptive Halton and Adaptive Uniform methods. A change in color greater than the Threshold value causes the adaptive methods to take the full number of samples specified by the Quality. If the color does not change as much, the adaptive method takes fewer samples and does not require as much processing time. Can range from 0.0 to 1.0. Setting Threshold to 0.0 has the same effect as turning off Adaptive On. Default=0.1. mental ray Connection Rollout Material Editor > Click a sample slot that contains a material other than a Multi/Sub-Object or a mental ray material. > mental ray Connection rollout The mental ray Connection rollout is available for all types of materials except the Multi/Sub-Object material and the mental ray materials themselves (for which it would be redundant). With this rollout you can add mental ray shading to conventional 3ds Max materials. These effects are visible only when you use the mental ray renderer on page 6230. mental ray Connection Rollout | 5385
