[Max] General Discussion / Re: Are people starting to ditch Forest Pack for Chaos Scatter?

« Last post by mase on Today at 09:23:08 »

In our studio, we have FP preset library with custom made presets for grass, bushes, trees, people etc. So moving to Chaos Scatter would be a hassle.

On the other hand, 90% of the time we only use the basic functions of FP and on very rare occasions do we turn to effects or other specific parts of FP. So in reality, most of it could definitely be achieved in Chaos Scatter. But a few times that I have tried I missed a few key functions from FP and so I switched back again.

Interesting to hear what others think.

Work in Progress/Tests / Re: dubcats secret little hideout

I remember you did a thread on virtual colour checkers.
How would that work with ACES Emulation?
Would you apply aces settings and your LUT and then use the output in lightroom to calibrate?
Colour management is all very new to me but its infinitely fascinating to get into the process of making sure my work output is accurate.

Hey!

I would capture a color checker passport at your current light intensity. Generate a camera profile. If your profile has a contrast curve, open it in 3DLUTCreator and remove it. This should give you a calibrated color and linear camera profile.
When you have a calibrated profile. The only thing you should care about is linear values. When it comes to real world albedos, we talk in linear %. If I tell you the brightest common paint is 94%, you should be able to input that value into "Value" in Corona Picker. But that is not how Corona Picker is working right now. So you have to convert 94% to sRGB. If you are thinking, why the hell do we have to gamma correct a linear value only to get a linear value, ask the Corona devs, it blows my mind every day. 94% is 97.2% sRGB, so this is the max real world scanned common paint value.

Another problem we have with the current Corona Picker is that the darkest common paint is "Jet Black" and it's 14,14,16 sRGB. Try to input these values into Corona Picker. You end up with 0,0,24 sRGB. This is a common problem when we try to sample real world values for products, the sRGB values might jump 10 sRGB. I'm using Vrays color map to fix this, because it let me adjust values separately with float values.

edit:

I haven't had much time to complete the last few guides on my site. But I want to share paint values with you guys as soon as possible, so I have remove all the unfinished stuff from the site.
I've only had time to add the 2019 Color Chart paints to the page, but have about 1 gazillion paints ready.
If you have a paint value, and are wondering how it would look with LRV and - IOR. Just post the values here, and I'll add them to the page when I get time.

How do you generate your profile?
Ive tried lightroom but it wont open exr and colour passport wont run on non raw formats.
3DLUT creator gives some really horrible results with the passport.

Is there any way you could give a slightly more in depth explanation of using it?
In terms of VFB setup, export format, and process to generate your DNT/LUT?

I still really want to know the correct workflow for this...

Just wondering if people are starting to ditch Forest Pack in favour of Chaos Scatter?

I've not used Chaos Scatter as yet, but am keen to hear other's thoughts...

Cheers,
Luke.

Good evening, cordial greetings to all! I'm sharing a beautiful project that we participated in the design and visualization of in conjunction with a prominent architectural firm. We worked on the main facade, the design of the side and rear patios, the pool, the master bedroom, the dressing room with en-suite bathroom, and the social area of the house.

[Max] I need help! / Re: CoronaMax2023.DLR and chaosScatter files take too long to load

« Last post by Aram Avetisyan on Yesterday at 22:43:19 »

Bumping this topic.

We on 3ds Max 2024 / Corona 12 Update 1 (Hotfix 1) and booting up a blank scene is super slow. The 2 main causes.

CoronaMax2024.dlr and ChaosScatterMax2024.dlt

Is there anyway to speed the process on these files?

Hi,

During v12 daily builds we have significantly improved the loading of Corona plugins. If they are significantly slower to load that other plugins during start up, then you probably need to check internet connection and/or license server, update it preferably. The slow loading of plugins may happen when e.g. Max is started sooner than license server is initiated, say after PC reboot.

[Max] I need help! / Re: Direct Visibility Override Color Issue

« Last post by maru on Yesterday at 17:31:32 »

The only idea I have is that perhaps you have automatic exposure enabled in the VFB? Please let me know if that's the case.
It shouldn't be behaving like this anyway, so if we confirm that, I will report it as a bug.
