Right fellers, Ernest B was thinking about this thread i think, but i thought i’d post it anyway.
GI Render Settings. What about them? i though we’d have an informative learning thread which will hopefully give us all a better insight and use out of our renderer.
Im a proffessional architectural visualiser and switched to C4D as my main render weapon from max about 3 years or so ago, and have always been lucky to have dual xeons provided for me as my render processors, so maybe i’ve picked up more bad habits about the understanding of what i’m actually doing than i should.
out of interest, here’s a quick example of a wip of the typical kind of thing i work on. this’ll give you an idea of the general complexity of a typical stand-alone model (sorry i’m not at liberty to provide test models) -
This particular scene has about 50 internal lights (w/shads) and a few external. Accuracy set to 100%, stoches = 100, min=100 and max=100, with a dd of 1 and a prepass size of 1/1. it rendered in 4 hours at a res of 2500 pixels wide on a dual xeon. (not too bad imo)
I’ve always gone for as high an accuracy setting as i can, with lower samples. i’ve always found this to be very visually pleasing as possible (in my case anyway)
I’ll typically use an accuracy set anywhere around the region of 95% +, with a stoch sample rate at around 100. my min samples usually range around the 30-50 mark, and the max samples are to suit the model, but again, usually around the 100-200 mark.
(I ALWAYS set a diffuse depth to 1. But this is personal choice - i prefer to keep a nice render speed and can successfully use infill omnis to compensate for lack of bounces, and i’ll use odd AA settings to for optomisation. But lets not argue about this, as it almost warrents it’s own thread.)
I’ve always found the combination of accuracy, min/max and stoches easy to use and set up, but not always understandable. particulaly the min settings.
to me, min settings are relevant for larger sparce un-interrupted areas of a mesh and max settings for intersections and complicated bits. Accuracy and general stoch samples for more of the realism side of things.
i.e. i’ll set a general min/max settings to get a non-blotchy image, completely indipendant of what i might set the accuracy and stoch samples.
but of course, they all work together too. but how can adding more min/max samples up the realism? all they seem to do is iron out the fiddly splotches. it’s the accuracy and stoch samples that determin the realism i thought.
why not use an accuracy over 90% as some peeps recently in here suggest you should never do? whats the point of the option to do it then? i use it to good effect :shrug:
i’ve been testing yet again with a lower accuracy and higher min/max/general settings and am getting nice results, but not as real as when i slap the accuracy up. also, the render time obviously shoots up the more samples i use.
so what do you think. what would you suggest for that model above there, with in view for realism of lighting.
the more understanding we can get the better.
cheers for your time. hope i havent drivelled on too much
