VRay Render Optimization [image] http://www.CGGallery.com/tutorials/vray_optimization/ There can often be a lot of confusion surrounding the topic of V-Ray’s sampling and what ‘ideal’ settings are. Many times you’ll see artists adopt the ‘Universal V-Ray Settings’ of having the Image Sampler (Ant…

Whenever you set your DoF Subdivs value higher than the AA Max value - it overrides the AA Max value. This is because the image sampler is responsible for sampling Depth Of Field or Motion Blur. So effectively your scene is set to 1 / 100 AA. In V-Ray 3.X the subdivision value is removed from the…

Three questions for those who are using Vray 3.x regarding this philosophy of optimization: 1)In Vray 3.x - in the AA settings there is now a place to increase the “min shading rate”. Does this take the place of changing all the subdivisions of the lights, materials, etc? [Here’s what the help say…

[image] How to get rid of glare 1)In Vray 3.x - in the AA settings there is now a place to increase the “min shading rate”. Does this take the place of changing all the subdivisions of the lights, materials, etc? It has the same effect, yes. 2) Are the principles all the same, in terms of ut…

Vlado covered the bases - but I’ll just add this comment on the Min Shade rate parameter: When deadlines are a factor and there isn’t enough time to individually tune each aspect of my scene, I find myself using the Min Shade Rate value to quickly balance my sampling in one easy go. Depending on y…

I did find it difficult getting sharp AA using this new method but I will try again on the next tight deadline. I may need to bring the min AA up from 1… Looks like there could be a LOT of testing involved with working out where the sweet-spot of this new method lies…

Thanks Vlado! And thanks RockinAkin for your rockin tutorial! [Just so you know, I prefer to read this kinda stuff than watch it on a video. Cheers!]

[image] scripting Output size It has the same effect, yes. Can you explain a bit more what exactly it’s changing in the subdivision?

[image] First time loading Activeshade for 3DMax 2013/Vray 2.30.01 and nothing happens! frowning Can you explain a bit more what exactly it’s changing in the subdivision? Min Shade Rate basically raises the maximum number of secondary samples taken in your scene, regardless of what your AA is …

[image] scripting Output size The “Adaptive subdivision” sampler is the odd one out, as it does not divide the shading subdivs by the AA samples. Been thinking more about “Adaptive Subdivision”, which tends to be the fastest solution for me most of the time…so, Vlado, this means, since it’s no…
