[Max] General Discussion / Re: Corona Alpha4 Benchmark scene

« on: 2014-10-15, 15:59:14 »

(for example my 2p 2680v2 node is exactly 3 times faster than 4930k in no overclock state).

Is your dual xeon's oc'd? If yes, at which speed and which mb?
Thank you.

Sorry maybe that was confusingly written, my Xeons aren't, but they run at all-core turbo, which is 3.2GHz (from default 2.8), so it's 40x3.2
Ivy Bridge v2 Xeons can't be overclocked because they have locked multiplier, although you can modify FSB, I suggest against, and it's only about 400MHz.

V3 (Haswell) Xeons can be overclocked if you use Workstation board from Asus with their Uefi with allow some 5-10 overclock...somehow, I didn't study, but I guess it's not FSB related.

Probably 2.. the benchmark doesn't scale well (actually at all). Current Alpha does (for example my 2p 2680v2 node is exactly 3 times faster than 4930k in no overclock state).
I really think there should be warning or update as originally I guess this wasn't actually benchmark but over the time it's now simply pointless and creates confusion.

For me all works well, but I don't do disp much at all so now.

Anyway, some good news, the heavy scene that took 50 seconds to do parsing on single core in SOA (but 2.2-2.4Ghz Xeon IvyBridge core only), and I think like 50sec plus on my i7 workstation (so single core of 3.6Ghz maybe in turbo),
now takes between 3-4 seconds to parse only. Here's screenshot :- ) I mean it without disp, it can't get much heavier than this so, it works, seem stable enough for me.

Did a comparison, on same machine (4930k, 48GB ram, SSD,etc..), after second render (and third,etc.. to avoid texture caching to interfere), the difference is brutal, it's literally 4seconds vs 50+ seconds (makes sense, it's 1 vs 12 threads).
Might do a Xeon (40 3.2Ghz threads :- ) ) soon too.

[Max] I need help! / Re: Help with vrayHDRI Dome light

« on: 2014-10-14, 22:20:36 »

Vray LightPortal is quite strange, but it's not good idea to use both Domelight + Portals at same time in Vray because they both will sample the light on top of each other.

In Corona it's quite simple and in lots of situation you can avoid portal completely, environment suffices, but if the window opening gets relatively small you can use them, they will only speed up the noise convergence, they don't alter light (unlike Vray, they're not light sources) or complicate sampling. Just the way you create them is maybe odd.. it's material that you should apply to (ideally 1 poly) plane, orientation shouldn't matter, in front of window openings.

You're mixing up Vray and Corona.

Vray needs Domelight alone to do importance sampling but also to be sampled direcly. VrayHDRi map is used for convenience of use (360 rotation, easy gamma change).
Corona can't read VrayLights (it's Vray light...) but is able to read VrayHDRi map for convenience. Corona can sample environment (either 3dsMax environment or Corona render settings environment) directly and doesn't need any analytical light source to be present in scene for it.

Corona image based lighting workflow:

1) Load HDRi in either a)Bitmap loader {32bit floating point, gamma 1.0} or b) VrayHDRi map {in Vray3.0 don't forget to turn proper mapping, it's no longer only for spherical maps by default}
2) Place in 3dsMax Environment slot or Corona render settings Environment slot
3) Render final image

Fantastic article! But no pictures of shaders = ) Looking forward to the movie as well, looks really nice.

Yeah it's less obvious, this seems like the same map. But it is actually often so repeating that CGI guys would think it's wrong :- ) It happens with quite few materials, like marble, which is often super-repetitive, but even clients think it's wrong unless I show them photo.

He might be great guy perhaps, but that blog annoyed me every time I came across it. French is so useful...for the whole world...not.

I'll start a blog in Zulu.

What is it actually ? A french version of Ronen Bekerman ?

No it's far simpler. It has fallof curve in diffuse slot that sort of looks like IOR 1.6, it goes for 70perc. near zero, then it goes up but plateaus again for the last 10perc, which is the angle at which we see the sofa "above".
Then instead of mixing black and white in as masks for bright and darker texture, the white mask uses a texture instead.
It's heavy scene that I can't open right now so I'll post that later but hope this describes it.

Ups, did a typo, was supposed to be 0.1, not super low as 0.01 :- ).

Yes but critique is critique, as long as it's not offensive and personal (ie:"you suck" and Dia's critique surely wasn't) it's whatever floats that person's boat :- ) The constructivness or other requirements for critique to ba valid are fallacy.It's up the person how he takes it or chooses to ignore.

General CG Discussion / Re: Unreal Engine 4 for ArchViz - Thoughts?

« on: 2014-10-13, 14:55:39 »

I am not saying that and even remotely compare the two. What I am saying is that Unreal 4 is starting to become a great alternative and hopefully that will force Lumion to change for better the product and the price tag.

Oh yeah, just checked the price. What the hell :- O When did that... ?
