Slow scene loading time

(1/2) > >>

Tom:
Hi everyone,

I experience very slow loading time with a pretty simple scene: 1.5M polygons total, 24 corona proxies, most textures are 4K .jpg, some 16bits tiff (very few, only for displacement).
The scene is 263MB only on disk (Compress on Save disabled), and when the scene is loaded it takes 16GB of RAM.

It takes 4mn10s to load the scene into 3dsMax 2022.3.3 with latest Corona (8 Hotfix 1) and 7s to save on my AMD 3990X, 128GB RAM PC.

Any idea where does the issue come from?

Thanks a lot for the help guys,

Try it without the proxys, corona proxy is not the best right now.

Tom:
Hi,

Thank you.
I turned all proxies into mesh: the result is slightly the same  :(

junchien:
As far as I know Corona has not been the best at loading agents. They tried to fix this in Corona V7, but it wasn't universally effective, and I mentioned in the forums that the different proxy mechanism caused a big difference in load times compared to Vray scenes. I don't know if you found Corona proxy files, when there are many. Caton is so serious that it defeats the original purpose of representation

Tom:
Thanks for your insight @junchien.

But I'm not sure to understand what you mean by 'Caton is so serious that it defeats the original purpose of representation'?
