[Max] I need help! / Re: Image colors changing after saving

@AlbertoMaciel - can you please explain how exactly you are saving your images (what format and settings in 3ds Max) and how exactly you are opening them?
If you could share a simple scene where the issue is reproducible, that would be great (even just a single teapot).
I am asking for this, because if we are able to reproduce it, then we may be able to:
- at least understand and explain what exactly is going on in your case
- fix something if it's wrong in Corona
- try Max 2024 + new versions of Corona to check if the issue still occurs there
Feel free to continue here or submit a support ticket at https://support.chaos.com/hc/en-us/requests/new

I can share this project with you guys. The displacement maps are huge but they don't make any different to reproduce my problem. The colors are still the same.
I won't upgrade to to 2024 for a while because you know.. plugins, etc.
I'll upload the file as soon as possible

I did read them all.
Most of the "fixes" were pretty much "Live with it, VFB displays different colors, you should fix on Photoshop" or something like that.
If the color profile is "wrong", it shouldn't display wrongly for everything that's on the screen? Or the color profile act different from software to software? Like, Photoshop, Image viewer, Pureref, EVERYTHING but VFB displays the image equally. VFB displays the image differently from everything else.

The threads do have answers and workaround solutions :- ). It's because there is no Color Profile in VFB, 3dsMax, or Corona, unless you're using 3dsMax 2024 which now supports color management.
Almost everything else does have color management, so it will be quite literally be only the VFB which is wrong.

The simplest solution is to install NoVideo sRGB clamp. 1-click solution. https://github.com/ledoge/novideo_srgb

I don't think I've ever heard about this. That's very interesting. I'm checking it out right now. Thank you!

Hi,

I understand that you are having some problems with differences in colors after saving your rendered Image from the VFB in Corona. This could be due to a few factors. I will suggest some possible solutions:

I hope this helps.

Thanks for your answer. Somehow, I missed it cause I didn't get a notification about a reply.
My monitor is color-corrected using Spyder5 Elite. The weird thing is that every other software (color corrected or not), displays the image the exact same way. VFB is the only different  one lol
I wish I could just update to max 2024 and get everything color correct but 3ds max developers are so lazy that community have to rely on plugins for everything and wait for them to be updated...

Hello!
I rendered a project and I noticed that after saving the image from the frame buffer, the image colors/contrast is changing a little bit
not sure if it's noticiable on the screenshot but here it is.
doesn't matter the format I save neither the software I open, the colors is actually being saved differently. This might be related to the daily build or I'm messing something up?

[Max] General Discussion / Re: Combining Displacement maps

« on: 2023-03-28, 16:02:11 »

Thanks, but simply mixing 2 maps isn't the problem, it's normalising the 2 displacement maps(zeroing out the scalar of the microsurface)

Because they are both 32bit full float images you can't simply mix them together because the ranges are wildly different.

EDIT: just figured it out. Using a Corona Mix node you can simply lower the multiplier of the microsurface map right down to normalise the 2.

Cheers.

I know the topic is old but I gotta ask... you used the CoronaMix as "MIX" or used any other blending mode?
I tried but I had mixed results.

Yes, I did. No answer so far...

Hello!
Every time I turn off/ restart my pc, the License server doesn't connect anymore and I need to reinstall it EVERY SINGLE TIME.
Right after I install it, it works properly.
Firewall exception is always there. How can I fix this?

[Max] I need help! / Re: Parsing scene taking way too long

Hi Alberto,

In response to your first question, "Is there a way to keep the scene loaded on slaves to make it usable?", we have this request logged in our system for further review by our developers.

(Internal ID=974574200)

Regarding your second question about the parsing scene taking too long, we would like to gather some more information to help us understand the issue you are experiencing. Can you please let us know the following:

1. What versions of Forest Pack, Corona, and 3ds Max you are using?
2. Are you using displacement in the animated vegetation in your scene? If so, could you try disabling the displacement for the entire scene by unchecking the "Displacement" option in the "Common" tab in the Corona Render setup dialog and see if it helps improve the parsing time?

Thank you for answering me! The info you requested:
- ForestPack 7.4.3, Corona 9 hotfix 1, 3ds Max 2023.3
- I am using some displacement, yes. I disabled it to test. No affect on the parsing scene time.
and the "animation" is not that the mesh itself is animated, It's just some variation on FP "transform" tab, to simulate a little bit of trees moving with the wind.

Hi Alberto.
I raised the same issue here https://forum.corona-renderer.com/index.php?topic=38987.0
The Corona team know there is an issue with FP and RC and suggested installing the latest daily build which they say may tackle the problem - I haven’t tried this yet.

People have mentioned using the instancing engine in RC but this did nothing apart from make the random RC materials not work.

If all else fails and your PC can handle it, collapse all RC objects to meshes. This should help - I went from 90 seconds to parse scene to 0 seconds. If it’s still an issue then you may have to collapse FP objects too (ouch!J.

Best of luck.

Thanks, man! Yeah, collapsing FP objects isn't an option, the scene will be extremely big and unworkable. I'm not using RC on this one.
Yeah, I got a good deal on two Threadrippers and I decided to buy them so I could invest more in animations... Which is actually not being very intuitive. I absolutely love corona but some things are just light years behind V-ray... some weird compatibilities issues.

[Max] I need help! / Parsing scene taking way too long

« on: 2023-01-07, 16:46:42 »

Hello guys!
I'm finally done building my "homemade" render farm with 3 Threadripppers, so I can jump on more complex animations.... at least that's what I thought.

On my first animation rendering test, the rendering itself is going extremely fast (3x Threadrippers 3995x) BUT the parsing time on DRServer is just absurd.
some more info:
- The scene itself (with all the textures and proxies), has 400mb
- Some animated vegetation distributed using ForestPack
- Each frame is taking about 4 min to render using all the 3 pc's

The "parsing scene" step is taking 16 minutes per frame and consumes 115 gb of ram. At this point, is just faster to render on a single PC, which is totally nonsense.

I'm not a developer but why transfer the same data over and over again for each frame, if it's the exact same project? It's not totally counter-intuitive?

My questions:
There's a way to keep the scene loaded on slaves to make it usable?
Using alternative distributed renders like Deadline, the scene will be parsed for each frame, in the same way?

[Max] General Discussion / Re: when will hair and fur work properly?

« on: 2021-09-21, 02:30:57 »

Well, personally, the H&F itself is AWFUL.
It's the same since 2008.
Vray has the vrayfur that works sweet. Fast, easy, great result. Corona should have his own fur as well.
Honestly, on works with hairy rug or any fur at all, I just choose to use Vray instead.
Besides that, the "problem" if you want one, is the shader. Users need to use some sketchy techniques to make a simple texture to work on fur and model at the same time.
Also waiting to get a corona fur solution but looks like developers aren't even thinking about it
