Ideally there would be a full scene memory report available from corona like the texture memory useage csv, but for materials and geometry.

Thats a good idea.

In the mean time I suppose the only thing I can think of is the old 50/50 way (remove 50%, hit render), do it again until the speed jumps up significantly, then you know which chunk to investigate.

Another idea which could give you more info (for geometry, and other info too), export one of those chunks as fbx (ascii not binary), then open the fbx with notepad. This will give you a tonne of info about the objects and its data but you would probably need a custom parser to get the data you want sufficiently, unless you dont mind scrolling though millions float values lol.

Hmm that is an interesting idea. Sounds like something an ai might be able to code quite well too.

But yes the whole 50/50 approach is what ive ended up having to do.

Im having a really weird issue with cryptomatte in photoshop from a CXR and the EXR.io plugin.
Every single mask layer is greyscale instead of pure white meaning whe used as masks, the resulting layer is semi transparent.
I have no idea whats causing this.

Any ideas? Im completely stuck without it.

Ok thanks, Seems a little misleading to name the pass 'Bloom & Glare interactive'

Im trying to save out a bloom and glare interactive pass from the CIE.
I have made some adjustments in the lightmix panel with intensity/tint. However it doesnt appear to affect the 'Bloom and glare interactive' pass as expected. Everything seems to stay at full intensity and its original color.

How can i get a bloom and glare pass from the CIE with the correct intensities and colours of the adjusted image?

Yeah ive tried forensic, its a great tool but not really what i need for this. Im getting really high parsing times all of a sudden on a live project and so far ive not managed to track down why. Ideally there would be a full scene memory report available from corona like the texture memory useage csv, but for materials and geometry.

Ive been having problems recently with some larger scenes and spending hours and hours debugging them to find a specific object thats causing the issue seems to be really inefficient.
Vray seems to have some great reporting tools whereby you can see a memory breakdown of your scene on a per object basis, stage by stage.
I know we have some amount of this in the error reporter currently but i was wondering if there are any maxscripts or debug/dev tools within corona that can give a more comprehensive breakdown of whats going on under the hood?

Its all well and good having a support system to upload problematic scenes to but it would be much more helpful if there were better reporting tools out there to help us debug scenes.

Thanks

Is it just me, or does the outline material not work with camera clipping? i.e. it will still render the clipped geometry.

Also it doesnt appear to respect the visibility of xrefs. If i have xrefs loaded but not visible, the outline material still renders them. If i have them loaded but not enabled, it still renders them. I have to fully unload the xrefs for it to stop rendering them.

[Max] I need help! / Geometry parsing issue
« on: 2025-07-24, 18:14:40 »
Sometimes i get a problematic object in a scene that causes parsing times to skyrocket. When this happens and i see its taking several minutes to parse I click stop. When i click stop it will take several minutes for the render window to respond, the stop button remains highlighted and the whole thing just freezes. Its becoming a real obstacle because it makes troubleshooting scenes a huge struggle. Im not getting any RAM warnings to suggest its an out-of-ram issue. Disabling displacement also has no effect.

Has anyone else had anything similar?

It seems to be railclone causing the problem. Ive tried the FAQ fix of converting it to a mesh but the issue doesnt go away and using embedded proxies for some reason causes half of the objects to not render.
Strangely, the railclone object will render fine on its own as will the scene its going into. But combining them has caused this excessive parsing time issue to surface with times in the tens of minutes sometimes. Its a simple railing.

There are two issues here:
1 - The path to CIE is wrong in the script - this will be fixed and the file will be updated in the Help Center
2 - The 33 files limit. I tried it and got a 59 files limit. After consulting with ChatGPT, it turns out there is a limit of characters that can be ran as a single command, and the current .bat script used to hit that limit. The exact number of processed files would depend on your filenames length. After torturing ChatGPT for some more time, I got a working PowerShell script which overcomes the character limit. Simply run the .bat file from the attached archive. It will think for a while and then spit out all the processed files. It may seems slow at first, but I don't think it is.

Ah brilliant troubleshooting, thanks Maru. I racked my brain as to why it could be limited. I would have never thought it was a fundamental character limit!
Perhaps it is time something was integrated to the CIE instead but thank you for your script.

I noticed recently that RichDirt has ceased sales.
https://www.enrichpro.com/en/richdirt/buy.html

If i recall, many years ago the team was in touch with the developer in some capacity. It seems that corona support was worked on but sales were low.

I had no idea that it even supported corona as theres no information on the site regarding what renderers are supported. The site is from a bygone era.

Anyway, i wanted to make the case that this should be kept alive by corona/chaos given its tight integration with archviz.

The nice thing to do would be to purchase it outright from the developer.
But i understand there are corporate policies and hurdles and technical practicalities that might make that impossible.

A native solution has been requested so often on these forums over the years and if theres even the slightest opportunity to integrate this solution it would be a huge time saver.
Yes there are methods with curvature and ao etc but nothing has ever come close to the ease of use of richdirt and richscene in my opinion.

Im highlighting the cessation of trading here, this isnt a feature request.
But i have made one so if you support the idea of a native dirt solution please do lend your vote!

[Max] I need help! / Re: LED Strip and noise levels
« on: 2025-07-16, 17:12:28 »
Depends where the noise is coming from. Is it from direct lighting? Or some bounced light? Maybe there is a reflective surface somewhere close to the lights?

The noise is coming directly from the LED light. The reflection on the floor is very noisy. The floor has some high frequency detail in the bump but isnt very glossy.
After 100 passes the noise is still prevalent sitting at around 12% in the VFB.

Hmm ok my mistake. My second question then would be whether there are any under the hood changes that could help with the noise in this setup?

[Max] I need help! / LED Strip and noise levels
« on: 2025-07-16, 14:25:09 »
Im working on a project that features hundreds of meters of LED Strips all of which are curved as they are around the outside edge of a racetrack. The only way i can currently achieve this is with a light material. However the light material warns users against using it as a main scene light source. The scene has dozens of overhead corona lights but The scene is also heavily influenced by the light from these led strips and is of course super noisy because of this.

Is there a better way of doing this?

I have also experienced this several times over many years. Seems to be a window focus issue as you say.

The batch image editor tool appears to be only working 33 frames at a time for me. Im having to move the 33 cxrs into a subfolder and run it repeatedly to get it to process the whole folder.

 I posted on the support system about an issue i was having with the batch script. However it turned out that the batch bat file was looking at the wrong exe. For some reason the folder Program Files/Corona/... contains the v12 image editor etc. whereas the folder Program files/Chaos/Corona/... contains the latest v13 and the batch tool was looking in the old folder. I doubt its related but it highlights a handful of small issues with the batching tool.

Im not sure if its an issue with the batch file or the latest CIE Cmd but it would be a great idea to integrate some batching ability into the CIE itself.
