Here's a question that always playing in my mind. which of the two options is better to use in the first bounce? i always use irradiance map in my first bounce coz its faster as far as rendering process is concerned. but one time i used QMC as my first bounce but the rendering time took me a century but achieved almost the same quality image output as IR. i which case what would be better?

thanks stephen for that fast response.
Here another throw-in question. i always set my IR in high mode in almost anythingwhether its a simple or a complex scene. in evaluating a scene, when and how to determine what amount of IR value necessary to put in a scene for me to save rendering time? |

yes brute force is qmc.
as for your other question, that can only be answered by experience. just clicking on HIGH when you render is not very good. doing this you dont optimise your scene for correct rendering with fastest times and quality, and you dont learn anything. i NEVER click on the high medium or low settings as they're never good enough for my needs. i always tweek those defaults. always. your best way to answer the question is for you to learn yourself. start test rendering and pressing buttons. try things out. experiment. thats the only real way to learn and get the best from your system. thats how the pros learn |

Second that. Besides, every scene is different and unique, with its own geometry, size, materials, etc. There is no standard settings (although Vlado has posted years ago some setup called Universal Settings, which is basically a very precise/time consuming setup that is meant to work with everything. Not very practical, though.)

Hi Mervin,
To be honest there is no such thing as 'better' in an all round sense, only 'better' for the particular project you are working on! It is one of VRay's great strengths that it provides a number of GI methods each of which have strengths and weaknesses depending on the type of scene/setup that you are working with. As has already been said though, just choosing a preset and going with it is not really the most optimal solution. With some learning of the controls you can slash render times whilst keeping image quality either equal to, or even higher than a simple preset choice. Regards Bri
