[Max] Bug Reporting / Re: Corona 12 Major Memory Leak

« on: Today at 10:17:18 »

Hi all, out of 7 "memory leak" reports we have received, we were provided with scenes only in 2 of them.
In one case we were not able to reproduce the issue, everything worked fine on our hardware, so it might be system-specific.
In the other one the issue is most likely related to caustics, but we are investigating it.

If you are using caustics in your "memory leak" scenes, please try disabling them and let us know if there is any improvement.

Hey Maru

I can't remember if I sent my scene or not, however, I wasn't using caustics.  That said, I haven't experienced the same issue since but ... I've not worked on that many new scenes.  If it happens again I'll be sure to upload a scene.

I'd still pay extra to bring the old displacement back :)

And going 0.5px is a bit overkill. Yeah maybe if you're rendering at 2k. But for bigger resolutions you just get diminishing returns below 1.0.
For 6-8k you could probably even go with 2.0px and get really similar results, with way better ram usage.

I'd love to be able to test it and find out

I discovered this a while back https://forum.corona-renderer.com/index.php?topic=40964.msg216903#msg216903

I'd still pay extra to bring the old displacement back :)

Now that we've all got machines with NASA level RAM quantities in order to work with Corona, we shouldn't be getting stuck on the number of triangles it can handle.

The more tech advances, the more clients want that extra detail, fidelity and resolution.

So this is either scene or hardware related.

Can you please tests and see if there is slowdown with lower resolutions, and with the default operator stack and then curves at the end?
Please try with VFB 1.0 too.
If there will still be a slowdown, I think we will need the scene to investigate it further. But I am not aware of many "slow VFB 2.0" reports.

Interesting, I do remember there were issues with the curves operator in VFB 1, I think I was the one who found it (https://forum.corona-renderer.com/index.php?topic=40316.0_ and you guys agreed it was an issue after initially not being able to replicate it, I was also using different hardware back then, this appears to be the same thing, but unfortunately I don't have time for all those tests.  I am happy to send the scene over though.

Here you go - https://drive.google.com/file/d/1FIWePCxhubwWXmP2lN_RQqjPdpNJCGqN/view?usp=sharing

That clearly demonstrates how sluggish the response is after adding the Curves operator and having it expanded.  Without Curves it's instant, with curves I have to wait for it to catch up when making a change

If it helps, the workstation is i'm working on an i9 13900KS, 192GB RAM, 4090 GFX Card

[Max] Bug Reporting / Sun and Sky Issue

« on: 2024-08-26, 00:07:30 »

This might be the way it's supposed to work, but ... if I have a Corona Sun in a daylight system with a Corona Sky in the Environment.  Everything works as expected.  If I take the time to say 9pm at night, you get the nice dusk sky BUT, if I turn the sun off at this point, the sky goes super bright?  Why is that?

Just to add, this also happens at any time of day?

[Max] Bug Reporting / Slow VFB

Not sure this is a bug or just an innefficient feature.  But the tone mapping stack responds really really slowly if you have a Curves operator expanded in the stack to show the histogram.

Turning on and off different operators such as Contrast and Tone Curve take forever to update in the render window, until you collapse the curve operator so the histogram isn't visible or get rid of it altogether.

Change the water to a chrome material temporarily and you'll see what it's reflecting that's causing it to look pink

This is really bugging me now.  C12 and the new VFB rewrite have not fixed this issue at all.  I can't be the only one experiencing it

I can't even find transparency in viewport preferences - am I being blind

Weird I'm having this exact problem right now, just started randomly

I'm finding the VFB in Corona 12 to be much slower as well.  Turning on and off the tone mapping stack takes longer than it should to register
