[Max] General Discussion / Corona 8, caustics include/exclude
« on: 2022-04-22, 11:25:29 »
Hi Corona team!
Just trying out the corona 8 caustics include/exclude. I had hoped it would allow us to stop certain objects from generating any reflective or refractive caustics but that doesn't seem to be the case. It looks like it stops objects from receiving caustics? is that correct?
My hope was that include/exclude would be a way to massively speed up the calculation of caustics by limiting it to say, water, pool surfaces and surrounding walls, but excluding everything else. This is pretty much the way we work at the moment - but we have to isolate geo, render a caustics pass and then comp it over.
Can someone clarify how we should be using include/exclude?
thanks!

[Max] I need help! / corona proxy & max scene loading times
« on: 2021-07-19, 18:52:32 »
Hi All,
Just wondering about corona proxies and max loading times. If i have a blank scene, with some heavy cgeo proxies that have no materials, shouldnt the time it takes to load the max scene be very quick? I though the geo was only loaded at render time, and thats the whole point of proxies?
all proxies are on box mode btw and set not to keep in memory.
thanks, Peter

General CG Discussion / Camera RAW to LUT
« on: 2021-04-14, 08:57:47 »
anyone got a good method of converting a camera RAW xmp (just the basic corrections) to a LUT?
The one I tried (https://sellfy.com/iwltbap/p/aq1y/) was far from accurate in that the overall brightness was way off, but maybe i should try it again

I'm getting a max crash which I think is related to ornatrix 6.3.6.25630
Can I send a max report for someone to look at?

General CG Discussion / 3dsmax service packs
« on: 2020-01-03, 12:57:19 »
It takes longer to install 3 service packs for max 2020 than it does to install windows and all other software we use.
What are Autodesk playing at???? Its been like this since max 2017. Where is the best place to complain to them?
Sorry, just had to let off steam!
Happy new year everyone :)

[Max] General Discussion / Rendering Tiles with Deadline - noise issue
« on: 2019-11-11, 13:26:47 »
Hi All,
Just wondering what the best approach is to make sure deadline tiled renders all have the same amount of noise? Should we be rendering with a pass limit or a noise threshold?
I will do some tests but just thought I would ask in case anyone has any experience with this
thanks!

[Max] General Discussion / Corona 5!
« on: 2019-11-05, 22:03:42 »
Great work Corona team!
Corona 5 is a massive step forward, overall ram usage, faster caustics, and of course 2.5d displacement. Really impressive considering the short development period.

[Max] I need help! / flipping (green) normals + displacement
« on: 2019-06-28, 10:52:16 »
Dawid (the famous Jawowski_3d) in our office noticed a weird thing with normals in conjunction with displacement and we are wondering why it happens. Its from dabarti scanned textures.
With just a displacement map:
With normals only:
With displacement plus normals:
With displacement plus normals with the green channel flipped:
To our eyes it looks like the green channel on the normals map is being flipped by corona when displacement is enabled, and we need to flip it to make it look correct.
Any ideas what is going on here?

[Max] Feature Requests / tiled exr tx textures
« on: 2019-02-22, 11:14:09 »
Hello All,
Couldn't find a topic about this so thought I would start one. Just wondering if coronabitmap supports tiled exr or tx formats?
I'm been testing a few scenes where I convert the large bitmaps (over 4k) to tiled exr or tx. Max loads a hell of a lot quicker and it can save a lot of RAM when rendering as well.
Pixamoon's bitmap relinking script can convert automatically, although it currently doesnt support coronabitmap.
any thoughts or experience in doing this?

[Max] General Discussion / Autobump concerns and 2d displacement ala vray
« on: 2018-11-28, 20:14:51 »
Hello friends,
I'm a bit out of the loop re: corona development but have just installed max2019 and corona 3 and was interested in testing out displacement.
One of our constant battles is with memory usage and displacement is part of that. I know you are probably sick of me going on about vray 2d displacement but it just worked and I never had any of the issues I have with 3d displacement.
Initial impression of autobump is that it doesn't really solve our problem and in the end just looks like an aggressive bump map. For displacement values of 2-4px in a 5k render it actually looks worse I would say, and for higher displacement pixel values it does definitely help but i don't think its a viable replacement or solution.
thoughts?

General CG Discussion / Thinkbox Deadline submission script customisation help?
« on: 2018-03-09, 18:35:54 »
Wondering if anyone has any experience with deadline and corona?
What I'd like to do is have the submission script report the target noise threshold in one of the 'extra info' columns in deadline monitor, and also have the monitor display the current noise threshold as well.
As far as I can work out, corona have done everything they need to do to make this possible, I just dont know how to set it up
thanks!

[Max] Bug Reporting / vrayhdri gamma set to 0
« on: 2017-11-03, 10:25:10 »
if you accidentally set gamma to 0 in a vrayhdri map, corona really doesnt like it, and restarting max seems to be the only way to cure it.
Just passing this on from Henry, havent checked myself

[Max] Resolved Bugs / max 2018 & corona starting on pressing enter
« on: 2017-10-10, 10:10:07 »
Hi all,
maybe this is a known issue, but many of us here have noticed that in max 2018 corona will start rendering even if you are just entering a numerical and pressing enter (for example it just happened when entering the displacement px setting).
very annoying. dont know if its a max issue or a corona issue.
thanks!
