[Max] Bug Reporting / Rendering Crash on CXR saving

« on: 2025-04-01, 02:47:03 »

Hi,

There has been some chats about this, but I could not find a clear solution, we have only noticed this issue since upgrading to V12.
We were previosuly on V9.
Max 2023, Corona version 12 Update 1 (Hotfix 1) .

The render finishes (passes + denosing) and then crashes.
The CXR appears to be saved in the folder but is 0kb file size, and no other render elements are saved.

We have found it connected to the resolution of the image.
6000 x 4780 works
7000 x 5576 crashes

We also tested the 7k render without the frame buffer on, and with the denosier off, and then denosier to final gather, but it still crashes.
We then tested saving to exr, which worked for 7k sized images up to 10k.
With exr we then try 15k but that crashed.

Another test rendering a teapot, at 12kx4k worked, but the densoier/save used 100GB of memory.

It would be good to understand the ram required relative to image pixel size for this save process, so we can be aware prior.

Note: we have have the most amount of ram possible in our consumer workstations, 192gb.

Machine spec:
AMD Ryzen 9 9950X 16-Core Processor  4.30 GHz
Ram 192 GB
OS Windows 11 Pro 24H2.

Thanks

No problem, now I know.
The native bitmap map preview seems correct to me.

thanks

Yes maybe, but you can see the difference between the standard max bitmap map, and the corona bitmap map.

update: The over material is the same so must be a viewing thing.

Thanks for the help

Ok thanks, I am seeing the difference when you hit the "View Image" button in the bitmap map.
Then zoom into it A 1:1.

They match in the slate editor preview here as well, so not sure which one the material actually uses, the slate editor preview or the "View Image" preview?

If you could please try the "View Image" button?

If you, or any could give it a go, that would be great.
Attached is the bitmap?

Yes these are at 100%, any other ideas.
I have checked the gamma in the defaultsettings.ini files as well and it seems normal (2.2, 2.2).

Getting a slightly contrasted bitmap when using the corona bitmap map compared to the standard max bitmap map and viewing on the screen via bridge?
Anyone else got this problem, see attachment.
Max 2016 + Corona V3

Thanks
