[Max] I need help! / Re: Still no OPEN button to open a CXR in the VFB?

« on: 2024-12-17, 14:19:42 »

Hi, You should be able to do region rendering. Find the video attached below.

:/

So the steps to bring an existing CXR rendering to the vfb and select the area I want to re-render is:
1- open it in the history tab
2- click on the pencil button to edit it in the vfb
3- click on render
4- very quickly select the region before other parts of the rendering get ruined with noise

The fact region render is unavailable when editing the file is a bug.

Alternative solution that I cannot understand why the devs don't implement:
1- Click on open cxr from the vfb
2- select region
3- click render.

Why can't that be done?
Open, together with save, are the most basic functions of any software since the 80s.
I don't get it.

Instead of clicking on resume you should click on edit icon.

Find a video attached.

I'm sorry, but one of the main reasons I need to just open a CXR is to draw a region and render it. The region button is not available when bringing an image the way you suggested.
Am I correct?

Oh! ok.
Thanks!

I'm stuck in the past on both Max and Corona but judging from the posts here I think you should be adding info on which Max versions you are using, too. It looks like Max is not getting the QA that it needs/deserves and there could be issues with Max' internal notification system (there were some in the past) that could interfere with how a renderer accesses the API. For example, a seemingly simple thing like hardware hit testing in the viewports for example could slow down IR quite a lot.

I'm using Max 2024 (latest update), the only thing that has changed each time is the last few versions of Corona.  So that makes Corona the common denominator?

What hardware?

I use Changsoo's script for GPU hit testing and so far I didn't notice any slowdown.

Not happening here...
Everything's working as expected I'd say except for a few bugs, but nothing serious.

Hardware / Re: AMD 9950x

« on: 2024-12-11, 14:33:47 »

I've been working on 2 3970x machines (identical) for 3-4 years now and I've had zero issues. The only thing is after long rendering sessions the frequency may drop to ~3.45GHz (less than the advertised 3.7) but that may be to cooling (using Noctuas NH-U14S single fan). Otherwise pretty stable system!

Thanks.
I'll need to consider them the next time

Hardware / Re: AMD 9950x

« on: 2024-12-11, 14:04:57 »

A little off-topic but I see this processor is not that far away in bencharks than my own threadripper 3970x that I bought for 3-4x the price (some years ago). Is the consumer line of AMDs now that capable?

Pretty much yes I'd say. The Zen 2 Threadrippers are now like 5 years old and we had 3 succeeding Zen generations in between. The "problem" however is that the top end also got a lot faster which means sure, the 9950x is as fast / faster as the 3970x but then the top end chip is still like 2.75x faster than the 9950x :)

They come with issues though, right? I mean, threadrippers. At least with corona. That's my impression after several years of reading here on the forum that those using them were not able to get the full performance. So I was always hesitant to spend that kind of money on more problems.
Is that true do you think?

But this seems to be an odd relationship. And I don't think AI is the issue.

Hardware / Re: AMD 9950x

« on: 2024-12-10, 16:04:51 »

I recently bought my 9950x.

After some tests (testing with 4 of my scenes), the improvement over the 7950x is 16-18%.
(Scene 1: 16.63% improvement
Scene 2: 17.71% improvement
Scene 3: 22.32% improvement
Scene 4: 16.44% improvement)

BUT, I didn't have the 7950x overclocked because the temps were already high at stock.
AMD claims the 9950x is more efficient so I enabled PBO, which led to a higher difference.

Hope this helps.

[Max] I need help! / Re: Still no OPEN button to open a CXR in the VFB?

« on: 2024-12-09, 14:26:46 »

CXRs are loaded into the History in the VFB 2, so the button is in the History tab :) EDIT and of course drag and drop works too, when that is more convenient.

So if I want to open a CXR and continue working with the image I still don't have an option to load the image in the VFB directly?
Because when loaded in the history tab, if I want to use regions to render something specific, I still need to click on "resume" in  the history tab, which will initiate the rendering and I have to click on cancel to get the image in the VFB. Is this correct?

I thought I read somewhere that now the VFB had an open button to open a CXR.

I cannot find it.
Where is it?

[Max] Bug Reporting / Corona 12 U1 - Stats different from VFB than saved CXR

« on: 2024-12-07, 20:06:58 »

When I render an image, the stats shown are different than when I save and retrieve the CXR.
Also, and this may have been the behaviour since forever, I don't know, but not all stats are saved. For example the noise % is missing in the CXR that I bring to the VFB.

General CG Discussion / Re: Poll - Do you profile your displays?

« on: 2024-12-06, 15:45:24 »

I'm fairly new to the calibrating / profiling game (if you don't account for hardware calibrating) and what I'm noticing is that calibrating / profiling is just one part of the game. The other part is setting your applications to work correctly according to the profiles / calibration used.

to be fair the ICC system is in theory quite "behind the scenes". profiling software usually takes care of loading the profile into Windows and done. everything just works. obviously it works as long as you stay within the ICC ecosystem...

My understanding is that up until now that Max has color management, it was either useless or too complicated to work on ICC profiling, so people would get discouraged and abandon the idea, especially when some tell you that even your textures need to be profiled correctly in order for the whole thing to work.
In most cases it's time that doesn't get paid and you can get by really well without doing any of that.

I understand that it would be the proper thing to do, but in reality, as Tom said, in some fields of work clients just don't care about the perfect colors. They care about images that look great. That can be done without the extra technical work of color profiling.

I disagree that it's as if in music production they didn't care about mastering or whatever. The eye is more forgiving than the ear IMO.

Having said that...Is there a good an easy guide for those using Max and photoshop that shows the whole process of establishing the ICC ecosystem?

The script should be unnecessary as we are improving the inbuilt lister, which you can try in the latest daily build - https://forum.corona-renderer.com/index.php?topic=38385.msg212584#msg212584

Hi Tom,

Does the lister allow to select several proxies and change their display in bulk?
If not, then this script is still necessary.
Hopefully Nik will update it and repost it.
