I am completely and utterly frustrated after upgrading to vray 3.6

[Neilg]

Do NOT change shading rate: there are very good reasons why it is set up as it is,

I cant keep up.

I could have sworn it was vlado himself that said the leave the AA low and raise the minimum shading rate as needed.
Now we're supposed to leave the minimum shading rate low and raise the AA? Isnt that much, much slower?


edit: just did a test in a scene i'm working in. aa at 1,5 and min shading rate at 128 finishes my region in 45s
Bringing the min shading rate down to 8 and raising the AA to 1,24 took 7 minutes to do the region - and it was noisier than the first in the reflections.

I can't really help you if i provide for links you do not read.

Can you explain how color mapping can be wrong?

Forum search LWF, or Linear Workflow.

Yes, that's what I thought you meant. I downloaded a sample scene from VRay a couple days ago and the MAX gamma was 1, which too me was wrong. Isn't MAX supposed to be 2.2 and VRay?

Thanks for the info ^Lele^ !

I read this in full - https://forums.chaosgroup.com/forum/...image-with-sp3
which has the AA set to 1,24 and uses low MSR and a reduction in noise threshold to clean the image. That's what i tried - it's slower. 7 minute render and the noise still isnt as clear as the 1 minute high-MSR one.
What part of my post makes you think i did not read it?

I also saw vlados post where he says to leave it alone. But I also searched the forums and found a post from vlado in 2015 where he says the leave the AA the same and raise the MSR.

isnt that scene just too dated?

and "leave MSR alone" post from 2015 where Vlado said he will get rid of it but its still there in NEXT so that you could decide if you want smoother GI or DOF for example ???

regarding IES strength - if you have wrong is file with weak light sometimes you need as much as 35000 lumens to actually see something...and no problems with noise

i think this post will again bring loads of confusion among people who read it.

I will try to forget what i read here and be happy our workflow works

The scene is in the current documents. I always fight interiors, now more than ever, so I am always looking for ways to make it less painful.

I think that this is it.

Bobby try setting AA and MSR as Neil dies and tell me if it does the trick for you.
For me, no chance at all. And i have all the values in max and in my scene set properly. (unless max preferences LUT 2.2 and all boxes checked is wrong)

[cheerioboy]

The tooltip on the max subdivs also mentions MSR

[PIXELBOX_SRO]

Yep and i really like using it on every day basis that why i am surprised i should leave it intact from someone like Lele.

So far, my interior is rendering nicely using 1/4 128. Last night with defaults I got a noisy mess in 8 hours and it's now clean with an estimated 1:45 to go.

[PIXELBOX_SRO]

what if you have lots of DOF in the scene? then setting MSR to 128 will mean very few samples for the DOF no? so at 128 GI woudl be clean and DOF noisy...

Yeah the settings I posted dont work at all for DOF. it works for quick, clean high res production renders - nothing too showy.
You have to lower MSR and use the high AA method to clean DOF up. technically motion blur too if it's extreme but if it's subtle you can get away with it.

Yeah Neil thanks just checking...this thread is very useful but until post No.14...then it starts to be very misleading
