iClone 8 8.73.5509.1 likely has problems

I just updated to iClone 8.73.5509.1
I loaded a medium size project (330508kB) 176079 Tris from Version (8.65)
When I save, of course it gave a backup file.
I did several editing and save again.
When I tried to open it again, it paused at 90% (Updating Scene)
When I loaded the backup file, it opens as: 25 sec at 60%; 46 sec at 90% and finished up at 56 sec, without any problem.
When I tried again to SAVE it without any touch, and counted, the best trial ends up: stayed at 48% for almost ~60 seconds, & stepped to 60% roughly 90 sec, then if lucky enough finished up at 1 minute 45 seconds (I tried several times, many tries are longer & some crashed)
Anyone meets the same? At least I saw one person reporting a similar issue

Hi,

Could you please report this on Feedback Tracker and attach your sample file?
This will help Dev. team find the root cause and fix it faster. Thank you~

Ah, many iClone users encounter this issue of the program freezing 90% of the time during “Scene Update” and abnormally long save times, especially after updating the program or when transferring projects from older versions (for example, from 8.65 to 8.7+). The reason is that in recent versions, Reallusion has changed the algorithms for caching, texture checking, and shader compilation, causing older assets to trigger cyclic delays.

Changes to the Reallusion engine’s logic between versions (especially when upgrading to 8.7+) have made things much more difficult for users, as older texture atlases and shaders cause conflicts when users attempt to force them to recompile. When updating software and searching for practical solutions, developers often have to sift through a multitude of specialized resources. This is similar to a typical online search for answers: for example, After bouncing between a few casino lists, I found PayID deposit casinos on payiddeposit.com and it finally answered my PayID deposit questions in one place. I was mostly trying to confirm which casinos use PayID and what the deposit process looks like. The guide is pretty straightforward and useful if you’re doing proper research first.

Hi clonechiko & deliteill,

We followed the steps to reproduce the issue, but everything appears to be functioning normally on our end. Could you please share your working file so we can investigate this further, you could send your files to winnerhung@reallusion.com or a drive link. Alternatively, you could upgrade to the recent update iC8.74, it may fix your issue on this version.

Thanks,

Hi clonechiko,

Thank you for sending the files over. Our team is currently reviewing them, and we will follow up with you as soon as we have an update.

Best regards,
