The Threadripper thread got little unwieldy to navigate since there is now lot of talk of cases, fans, gpus or general building advice.
I thought it would be easier if these questions were posted separately so people can still find their answers that concern Threadripper.

Remember, do a quick search on Google, Reddit, etc.. to see if people didn't answer this in-depth. Often time for Workstation type question, that's not the case, but othertime, with general building advice, it is.

I can't attend so I am giving away our two tickets (300 euro) for free for anyone who can still manage to attend this Thursday (16th) to Saturday in Sofia, Bulgaria.
You can buy cheap RyanAir tickets there ;- ).

Off-Topic / Public blacklist of Light-Visual studio
« on: 2019-04-12, 15:38:32 »
Well, I'll add it up here, just so you know that your work could be stolen just like mine and you shouldn't tolerate reposts from accounts like this.
Belarussian studio Light-Visual has stolen my work (see screenshots) which they pretend to be theirs. Likewise, of few photographers what they pretend is their CGI ;- ).

On Instagram they repost other Archviz work without knowing of the artists, sometimes tag them which is irrelevant because they do it to market their own services.
Unless you like parasites like these to get job from your work and potentially tarnish your reputation (remember, many people never read anything on internet, clients can think the work is theirs even after they botch the work) I would look through their account and report it to Instagram.

Hardware / Reviews for Xeon W-3175X are out
« on: 2019-01-30, 16:30:40 »
So the 28core miracle from Intel finally surfaced to the market and reviews have been pouring out:,5976.html

Not the best review sites, but Kitguru always takes his time :- ).

I am actually kind of baffled by these reviews...they compare 3175X which comes by default with unlocked TDP and thus reaches 3.8Ghz+ All-core turbo at easily 360W+ to stock 2990WX with its 250W and then proclaim how it's clear winner.
It doesn't come soldered and reaches beyond 100C at 500W+ when overclocking to overcome 2990WX. At this point, it also overpowers the bundled (right now it comes only in prepackaged OEM builds) Asetek AIO with 70dB (fullscale airplane mode).

The 3175X does come out of top with absolute overclocking potential, even reaching 6500+ Cinebench R15 points. But it suffers heavy AVX penalty, setting back its Corona potential. Some reviewers reached 800W power draw for AVX512 at -1Ghz penalty :- ) It better not burn your house.

The price is surprisingly rather fair. That is, until 48core Threadripper surfaces.

You can only buy it from BOXX and other OEMs. So multiply the price for full build buy two. Then buy 3 threadrippers instead.

Edit: So Derbauer already did delid, got 10C difference. And apparently the published price is red herring, akin to RTX ;- ) Price in Europe will be 4500 Euro from CaseKing.

Hardware / Upcoming HEDT from Intel ( i9 on LGA 3647)
« on: 2018-10-08, 15:04:14 »
The 28C i9 will require up to 32 VRM phases for juice lol. I think that's about it regarding i9 vs Threadripper...
(yeah shit source, but the first one today).

On other hand, it will have six-channel memory support, and of course all those directly to single-die chip. So it might be the ultimate CPU for Corona which seems to be somehow memory starved on Threadripper unfortunately.
I wonder what the price will be. 2999 euro ? 3999 euro ? At that price point you might as well go GPU-rendering for good.

Gallery / Classical apartment product showcase
« on: 2018-04-03, 20:05:54 »
Howdy :- ). Haven't posted any work for almost a year. We have done in fact, many in meantime, but the most interesting ones are under NDA and other, bit bland ;- ).
But I am very proud of this one. Small in scope and done for nice architectural duo AlexAllen, we were commissioned by them to create classsical apartment and render their beautiful Lightnings and design products.

I am hotlinking these images from Behance, I wonder if that will prove problematic but it's such a pain to upload to Corona otherwise.

Much better to just watch it there directly ;- )

When using CoronaMix node ( for example in my use LinearAdd, where top layer is highpassed map and lower level is albedo color ) with the togglebox "show in viewport" (doesn't matter if it's done at node level, or the whole shader level), the shader doesn't retain this state after re-opening the scene, or 3dsMax session.

What happens instead, is that it shows some random color (or maybe there is some logic behind that color, but I haven't been able to deduce it). Toggling "show in viewport" (which does remain checked, just with this bug) off and on again, doesn't correct it, but returns this color again. Once again, doesn't matter if togging on/off happens on shader level on node level only.

What fixes it, is going into top layer of CoronaMix node, toggling on/off said particular bitmap loaded there, and then going back and toggling the node or shader, and it works again.

This makes CoronaMix node unusable in Diffuse slot because the shader won't look correctly in viewport after reloading 3dsMax session.

This issue doesn't require particular scene, I've been able to make it in different Max versions and it happens in empty scene as well. But in my case, 3dsMax 2016.

Gallery / Impremta Garden (+ breakdowns )
« on: 2017-09-12, 00:46:38 »
Hi everyone,

I didn't post any project for past half-year and finally decided to start doing so again. I was quite tired from work and then decided to take long break over the summer, which didn't work out well as I've (with Veronika) instead started a new sort of project/work/stuff...that's maybe CGI connected or maybe even not :- ) But I at least got to start posting one of many projects sitting sadly on our harddrive. Well at least those not under NDA.

Impremta Garden is one of two Mallorcan real-estate projects we finished (back in April) and it didn't look like much when I got the brief. It was...empty, dark with not that many windows, with some potential. But as I delved deeper into materials and playing with light inside it, it showed its real potential and we're both very proud of it now, I am very happy how it looks. And I am never happy or satisfied...with anything.

Below is some selection of images from it.

Rendered in C-Ray at typical 8k resolution (and it took forever time, don't ask). I downsampled those to 1/4 at 2560px/Jpeg9 so it's watchable (hopefully?) on web :- ). All questions welcome but please don't kill me with pixel-peeping, I am only human.

Breakdowns/Tutorials are in second post right below ( link )

And few more bellow :- ) I didn't want to destroy your bandwidth, the above are all Jpeg(9quality) but quite a lot of them.

There is little bit more user-friendly way to watch it on Behance

Jobs / Freelance furniture/asset modeler
« on: 2017-05-23, 14:21:39 »
We're little bit swamped right now and I could use help of talented modeler if someone has time.

I strongly prefer classic subdiv modeling as opposed to marvelous designer when in comes to chair/sofas. Texturing/Materials are not needed.
Please indicate how much you would charge but quality is indicator, not price. I pay immediately and you will retain all rights to the model and can sell it further or whatever.

Attached are three examples of what I would need currently. Right now I have 2 weeks time budget for these.

If anyone is willing and has time, please write me to info{@}

Gallery / SkyPark by Zaha Hadid
« on: 2016-12-08, 17:00:00 »
Hi guys, lots of nice projects posted on forums these days, would like to join with few. This is project Veronika and I had done back in summer, using Corona using Corona 1.4.

We were given full freedom with this project, and had done interior design (to match the upper-middle class clientelle), styling, camera choices and photography. I wish we could have worked on the penthouses, but those were sold to foreign investors without need for images :- )

I will try to answer any question in bursts, some time ago started using ColdTurkey to block forums and lot of sites to avoid procrastrinating :- ) Highly suggest, heh. If you need faster answer, you can ask under FB post.
I will post two short making offs under this post.

Behance (easier browsing experience here due to new full-screen mode)

See attached example inside CoronaColor.

If the sRGB is checked, CoronaColor reports the value as linear (during RC candidates, it was linear check-box).

Secondly, in either case, the "Value" is always in sRGB. Is this by design ? It's bad name in such case. And exact linear value has to by typed into R/G/B values instead.

Funny enough, it matches if I check "values are in linear space" check-box in CoronaColor.

So what's happening ? Is new picker wrong ? is CoronaColor wrong ? It's behaving very confusingly.

As title.

When creating MixMap ( in my case, Linear Light in sRGB mode, highpass layer above, color bellow), it shows just fine the result. After saving and re-opening the scene, it doesn't, and clicking on the button does nothing, it will only show the color (of something ?).

[Max] Resolved Bugs / LUT clamps the image
« on: 2016-10-18, 17:59:47 »
As title :- ). But unnecessary and not wanted. See illustration

VFB+ provides same look with same LUT, but doesn't clamp the image, retains full dynamic range for post-production ( including white-balance which required dynamic range to work properly).

[Max] Resolved Feature Requests / Extended Albedo pass
« on: 2016-10-17, 15:26:56 »
Currently, the Albedo shines RED with overbright materials, I would like to to shine BLUE (for example) for over-dark materials.

Could the range also be specified ? Either to be user-specified, or just make the default 50-240 sRGB.

This concerns purely diffuse albedo, not even sure how the pass currently treats metals/specular only.

I've noticed for some time my slaves are super slow to kick-up, which is odd given they're all dual-xeon monsters. It can't be the scene given it starts in seconds on master workstation.

Monitoring task manager showed me the whole precomputation is happening in single-thread only, i.e transforming vertices, parsing the scene and seemingly also large part of secondary GI ?

Is this intended behavior or some bug along the path.
