Unfortunately i can't help you, i don't use cryptomatte, but i think this should not happen. Maybe try to post a new topic in i need help board, or leave a message in this topic and someone more knowledgeable should help you to solve this issue.

[Max] Feature Requests / Re: Better implementation of corona maps in Nitrous viewport

@Jpjapers by saying "more complex material graphs in viewport", what exactly do you mean? What would you like to be added?

[Max] I need help! / Re: Make an object invisible in rendering but still acts as a solid

« Last post by maru on Today at 11:32:05 »

Hey Maru and thanks for your suggestion :) My aim is to actually block the light casted by the sky on the tree leaves (so they appear less translucent), without the plane casting any shadows to the foreground. I hope I managed to better explain myself here, it's tricky this one :')
I'll check your response on the other post and try it out, much appreciated!

"Blocking the light cast by the sky on the tree leaves" sounds exactly the same as "casting shadow" to me. Sorry, but I don't think there is any other solution.
Adjusting the leaf material, as dj_buckley suggested, sounds like an easier solution.

[Max] I need help! / Re: Black rectangles in saved images

« Last post by maru on Today at 11:27:41 »

Hi guys,

I have been experiencing the same issue for a while. It happened randomly. In the render frame everything is OK but when the render is saved, it has a random sized black rectangle area. It doesn't happen if I save the render as CXR, so I had to save CXR and use copy/paste to photoshop and save the image. I just installed the new hotfix 2, let's see if it solved the issue.

Regards

This should be solved in V11 Hotfix2. If it's still happening there, please contact us at https://support.chaos.com/hc/en-us/requests/new

[Max] Corona Goodies - User Contributions / Re: AgX in Corona

More of AgX by Troy Sobotka - this time his Resolve version of it (quite different) married with a film look from Arri:

note: it does require a string option to turn off VFB's sRGB view lut so might be a bit more cumbersome to use.

Thank you so much. When I use cryptomatte renderelement as mask, this issue occurs. Do you have any solution for it?

[C4D] I need help! / Re: Multishader multipass masks?

« Last post by TeoRossi93 on Today at 10:55:44 »

Hi, would create 2 materials and give them each a material ID from the Advanced settings in the material. Scatter 2 objects and assign each a different mat. In the multipass settings, make 2 masks and enable Material ID and give them the same number as the materials. Render and you will have a different alpha for each. Here's an example.

Hi Bengamin,

thanks for the answer but unlickily this is not gonna work with my current animation setup.
I'm attaching my scene here so you could have a look at it. I can't change the rig at the moment, the only chance I have is to make the multishader masks work properly.

[Max] General Discussion / Re: Roughness implementation correct?

« Last post by piotrus3333 on Today at 10:40:34 »

The thing I find different about CoronaPhysicalMtl and energy conservation is actually too much energy reflected at low Base Color values like 0.02-0.04.

I'm talking nonsense - CoronaPhysicalMtl is actually a bit darker than StandardSurface.

What is odd though is that CoronaPhysicalMtl returns at F0 (furnace test, GeoSphere mesh, Base Color 0.18, full roughness, ior 1.5) less than 0.18 float.

Compared with VRayMtl here:

That's a cool cat and very nice looking smart materials! But what's with those ugly grey edges? Especially visible on the first couple images.

[Max] Feature Requests / Re: Render time and noise level to be shown in saved CXR render file

« Last post by Frood on Today at 09:16:01 »

Corona has always been a bit stingy with stats data (and logging) and a convenient option to access it would be nice (at least in CIE), yes. Additionally all stats should be included in EXR metadata as well at best.

But Corona already stores the most important info in CRXs. Use exiftool to extract it like:

Code: [Select]

exiftool -CoronaStats* -CoronaRenderStamp* yourfile.cxr
And note that the renderstamp is always saved into the CRX, even when not activated in the render settings. So you can use it to store various data additionally. if you write a batch with something like above, you can even integrate it into windows explorer context menu of CXR files (image).


Good Luck
