This is useful for fine-tuning the antialiasing of the image. Show Samples - if this is on, V-Ray will show an image where the pixel color is determined by the number of samples taken at this pixel where blue means that the Min subdivs was used and red means that the Max subdivs is used. Threshold - the threshold that will be used to determine if a pixel needs more samples. When this is off, the Threshold parameter will be used instead.
Use DMC sampler threshold- when this is on, V-Ray will use the threshold specified in the DMC Sampler to determine if more samples are needed for a pixel. Note that V-Ray may take less than the maximum number of samples, if the difference in intensity of the neighboring pixels is small enough. 4 subdivs produces a maximum of 16 samples). The actual maximum number of samples is the square of this number (e.g. Max subdivs - determines the maximum number of samples for a pixel. The actual number of samples is the square of this number (e.g.
You will rarely need to set this to more than 1, except if you have very thin lines that are not captured correctly, or fast moving objects if you use motion blur. Min subdivs - determines the initial (minimum) number of samples taken for each pixel. It also takes up less RAM than the Adaptive subdivision sampler. This is the preferred sampler for images with lots of small details and/or blurry effects (DOF, motion blur, glossy reflections etc). You can also use the interval format N-M of two integers separated by '-' for sequential object IDs Render mask object IDs - the list of Object IDs used by the render mask. You can assign an object ID for a certain object with the VRayObjectProperty.
This cannot be done for the Adaptive subdivision sampler - it does not know in advance how many samples will be computed for a pixel therefore it needs to maintain a constant (high) accuracy. tracing fewer shadow rays) for the individual image samples. With the Fixed and Adaptive samplers, V-Ray knows in advance how many image samples will be taken for a pixel therefore, it can optimize the computation of some values (the area light for example) so that the final image result is similar, while actually those values are computed with lower accuracy (i.e. Furthermore, each image sample was quite costly to compute - there is an irradiance map and an area light, which (especially the area light) need a lot of computations. Lots of image samples were required to smooth this out. Some parts of the image are quite "noisy" because of the fine bump map. Why is that? Here is the non-antialiased image, to give an idea of what the image samplers had to deal with.
