Will be OptiX (NVIDIA GPU AI denoiser 6.5.0) work with High Quality image filter? Thanks

No, as that would require NVIDIA to retrain their AI using the different type of noise pattern given by the High Quality Filtering.

Another example of a complex scene in terms of materials. After the conversion, you will have to edit all the materials, since there is not a single hit. My cannon is bronze, the converter says it’s not metal, but how does the system know where the metal is, where it’s not metal, at the moment it can only be determined by a person. Different behavior of Glossiness and reflections. As a result, you need to tweak and optimize everything. With this quality and accuracy of the conversion, the question arises, and will it also work with Vray? Converting to physical material is a point function, but not as global as it is now.

God forbid if you release this converter to the masses like this, even with all the fixes, but I’m sure there will be a lot of headaches for people, many will not appreciate it.

Hi Feodor,

Would you be able to send us this scene also? We would need the scene in order to figure out what is going wrong here.

Thanks,

Rowan

Hi guys, i just start trying Corona 7 last daily. One thing i have noticed is that in some models specifically on archmodels collection 171, when converting from CoronaLegacyMtl to the new CoronaPhysical material i have an issue with the refraction. For some reason the guy that made the models had the refraction level 1 but the color black so even if in the legacy material that’s not a problem and won’t translate as glass, after the conversion to physical material it is a problem since the leaf looks like glass. As far as I can understand in the conversion takes into account only the refraction amount and not the legacy material refraction color. I hope that makes sense!

Hello annkos, please could you provide us some of these models with the corresponding materials or create for us some reproduction case we might investigate?

Hey Devs,

Can i please make a relatively simple request if it isnt possible already? So when creating proxies using built in script, when there is existing proxy files, it asks only to overrite - is it possible to add a function to ‘use existing’ from within that folder?
If not can this somehow be added? would be super helpful

after working with corona7 now for a while, i find it a bit odd, that you named the old/standard corona-material into CoronaLegacyMtl.
I constanlty run into errors with various scripts etc, that won’t recognise coronaphysicalMtl which might became the new standard.

would prefer also for compatibility issues, that the old material would still be named without “legacy” … as the differentiation is already done with the addition of “physical”…

also the new corona-converter is a a bit odd… as it only converts materials into the new physical-material… there seems no option converting it into the “older” legacy-material…at least not for the seleted objects i want to convert.

Well, one of the reasons we chose to rename the materials was to prevent confusion

We renamed the old material to legacy to make it explicit in the UI that this is something that shouldn’t be used in new projects and might be removed some time in the future. On the other hand the material should still be accessible from maxscript using the old CoronaMtl name. If you have some script that should work with the legacy material and doesn’t work anymore, please send us the script and we’ll take a look.

For similar reason we chose to name the new material CoronaPhysicalMtl instead of just reusing the CoronaMtl name to avoid any confusion with legacy scripts, tutorials, screenshots, etc. which would now refer to the new material which looks and behaves different.

Just noticed you guys continue on the sky model with aerial perspective. Now we really want to test all those features together with improved tone mapping

Wow! This is a nice surprise. You had it under the sleeve, huh?

[nakama]

not sure if this is a wanted feature…

but everytime i install a new build, all my corona-system settings get resetted.
Would be great if individual settings like “output autosave” could be kept…

Hi,

That doesn’t sound right at all. I will take a look into it and let you know.

EDIT: I wasn’t able to reproduce this, which version of 3ds Max are you using? And how are you updating Corona, just running the installer and updating the previous version or uninstalling first?

Not sure if you can disclose it or not, but will the new tone mapping include support for OCIO/ACES or not?

[Feodor]

Good afternoon! Detected unstable Corona behavior during rendering. After running on the render after some time, 1-10 minutes, possibly longer, 3ds max crashes without any messages. This starts happening starting with the “corona-7-3dsmax-daily-2021-05-10.exe”. In an earlier build, this is not observed. I send you a scene “CD_2021.rar” to identify the bug.

Used 3ds max 2021

Thank you

Hello Feodor!

Thank you for reporting this to us, I have been able to reproduce it as well. We will update you on any progress.

“Not sure if you can disclose it or not,”

Well I think we answered that part

Cant tell if this is Max 2022 or the last few corona dalies but when I select corona bitmap the file loader doesnt open to select a bitmap. Pressing the load image button doesnt do anything either so had to just use the Max bitmap loader. Renders fine with existing corona bitmaps but they cant be changed as the loader doesnt pop up for me.

Hi

When copying material in specular mode, the parameter changes the range from 1 to 3 (see attached)

Hi,

This seems to work fine for me.. How are you trying to open the bitmap through the slate material editor or some other way? If possible you you provide a short screen recording of the issue and I will investigate further.

Thanks,

Hi,

Thanks for reporting this, I can reproduce it and I will report it for our dev team to fix.

Cheers,
