I did find: rs.RenderAntialias(0) I believe that only impacts the Rhino Render.

import rhinoscriptsyntax as rs rs.Command ('visOptions') I need to adjust Image Sampler and DMC Sampler.

The only thing I could find is the command below and it just opens the V-Ray options window. However, a small number of passes cannot be distributed effectively across several threads. Currently trying to make a Python script that will make changes to V-Ray options. In general, a light cache computed with a smaller number of passes may be less noisy than a light cache computed with more passes for the same number of samples. V-Ray for SketchUp 83 Adaptive Subdivisions control The default setting for Adaptive Subdivision can produce a good result. This ensures that the light cache is consistent across computers with a different number of CPUs. Intensity Exponential can maintain the RGB ratio, and will only affect the color intensity, light image on the bottom right. Each pass is rendered in a separate thread independently of the other passes. Number of Passes - The light cache is computed in several passes, which are then combined into the final light cache.The actual number of paths is the squared value of the subdivs (the default 1000 subdivs mean that 1 000 000 paths will be traced from the camera. Subdivs - Determines how many paths are traced from the camera.You are making sure that whatever happens, the minimum number of samples for a glossy. The min samples parameter is there for safety reasons if your adaptive amount is set to 1.0, Vray sometimes cannot make the decision if it needs more reflection samples. A value of 1.0 means Vray is fully adaptive, in some cases this is desirable but it is down to personal preference. Each of the bounces in the path stores the illumination from the rest of the path into a 3d structure. An adaptive amount of 0.7 means Vray will use a fixed amount of 30 and have the remaining 70 as adaptive samples.

Antialiasing filter - Sharp Quadratic or cutmull-Rom. Light Cache - The light map is built by tracing many eye paths from the camera. HI Iam Purush, What is the easy setting of vray rendering, now iam using, Image sampler - Adaptive subdivision.For the "Light Cache" set the "Subdivs" to 1500, and for "No of Passes" set the value to 8.
