[Max] Corona Goodies - User Contributions / Re: Corona Physical to Autodesk Physical Material Converter

« on: 2023-09-13, 14:32:35 »

Thanks James!

To be fair, for our purposes using base layer instead and ignoring everything that happens in CoronaMix is good enough (same with any other non-supported maps).

Whenever we export our 3ds Max model outside to other software it's usually for architects to do some further design adjustments. They don't need to see the exact shader representation in whatever software they import model to, it's just to make it easier for them to read different materiality, not having to go through the hassle of differientiating glass from walls etc.

So as long as whatever can be converted is processed, and whatever is not yet supported receives a warning (ie. that it has been removed from the shader node stack) - we are all good!

This might obviously not be perfect for some other use cases, but for us it's more important that the conversion is actually succesfull rather than 100% acurate.

Hi James!
Many thanks for you script, it works great!
I encoutered a problem in one of our scenese where it gave me an error referring to one of the Corona Mix maps we were using.
All converted fine when I removed this map from the scene. Shall the script be also converting Corona Mix map  to composite?
Thanks!

Same here,
We're paying for Vantage already even though we need to go through the hassle of converting everything from Corona to Vray. We do plenty of animations and Vantage is really handy to present drafts/previz stuff to clients.
We're pretty dissapointed that is has been taken off Vray Premium Subscribtion though. On the other hand this allows us to only rent it during months we actually use it.

[Scatter] Resolved Bugs in 3ds Max / Re: Chaos Scatters heavily affecting viewport FPS

Bumping topic up for v11 since I've seen there are some new features being added to scatter in daily builds.
Would be great to resolve the performance issues of the existing features if possible.

From our experience, using texture maps for density is slowing Chaos Scatter down significantly on the more complex steups.

+1 for parsing improvements for animations.
Every realease I'm disappointed that it has not made anywhere outside of "pool of big ideas" on Trello board.
No other feature will have such a direct impact on cost of animation rendering as this one could have...

[Max] General Discussion / Re: Corona 10 - Corona Render Assets loading very slow

« on: 2023-08-22, 19:17:15 »

Hi all, we did some tests here and the same scenes appear to be opening slower in V10 compared to V9, however we were not able to reproduce such drastic slowdowns as "20+ minutes". It's only ~10 seconds slower in case of larger scenes with many objects, xrefs, textures, 3rd party plugins, etc (we are not using a teapot scene for this). The files were loaded locally from an M2 drive in 3ds Max 2024 and the time was measured between pressing "open" and being able to move in the viewport.

I assume these tests are being done on the archived scenes that all link to the assets stored in one folder?
The real life scenraio is often that assets are spread across various network locations. Max was always taking longer time to load such scenes, but maybe there's even bigger difference in such scenario between Corona 9 and 10?

[Max] Resolved Bugs / Re: Crash with OSL wParallax

« on: 2023-08-03, 10:26:38 »

The box method is just not as convenient as using simple plane behind the window. It's much harder to set up procedurally if there are many building types involved.
Planes + OSL are so much better and faster to use, if only they weren't crashing.

Yep, this is definately not solved yet.
We would love to use it in production, but simply cannot due to instability.

Did you try to disable update automatically option in scatter's viewport display rollout? Maybe that could help somehow with performance?

Hi Romullus, yes just tried this, not a tiny difference in performace, just as bad as with autoupdate.
I did another test, added scatter with 50000 boxes scattered on the simple plane. This scene with highpoly models, 10mln Verts, is playing at 20FPS without scatter.
After adding the box scatter it drops down to 10FPS. Even if I hide scatter, it remains at 10FPS, only disabling or removing scatter brings back 20FPS performance.

Remember that I have flexibility to disable/enable scatters only if they are physically in the scene. If they are xrefed, there's nothing that I can do to improve performance rather than disabling xref.
Scatters are rarely xrefed on their own, usually they are part of landscape/context file, with all the paving and other elemnts that are essential to be visible in the viewport while animating cameras.
Real pain to deal with.

Hi,
Just bumping this one up. Would be great if this could be improved in v10.

It's really hard to work on animating cameras if viewport has 5FPS, and it bacame a real pain in our recent projects.
Disabling Chaos Scatters is not always an option, often we have them as a part of an xref, so in order to improve viewport performance in master file, an xref has to be opened and scatters disabled there....

Can we expect that team will have a chance to look at it in the new release?

I would personally love something like this that works the other way too. Corona TO physical for the times where you need to share a model as say an FBX and the other party doesnt have corona.

This! Would love to have such funcionality too.

[Max] Bug Reporting / Re: SME Very Slow on Corona 10

« on: 2023-06-26, 12:50:19 »

Really hope this it a top priority thing to address in Corona 11, if indeed not much has changed.
It's really frustrating that other engines are handling SME much better than Corona does.

[Max] General Discussion / Re: Max extremely slow to close

« on: 2023-05-25, 17:57:18 »

Our Studio uses both intel and AMD and Max closing times are just as bad on both platforms.
It has surely sth to do with plugins we use (or how 3ds Max is managing them), it's hard to isolate it to one in particular though as we use many.
Very annoying so we also starte to simply fore quit max after saving.
