Iclone is great and there are many great new feature that are amazing (motion director, LiveFace, Look at features) but unfortunately, using them on 6 to 7 characters in a 5 minutes project leads to crashes happening 20 to 30 times a day which is a real PITA.

I know I can hide some actors but is there a way to desactivate some of them to avoid crashes?  This is not the best way to work but if disabling 2 or 3 actors while I work on the 3 or 4 other actors can help this would be a solution to avoid restarting Iclone 30 times a day.

I lready sumbitted a ticket but unfortunately, I need to make it work now so any tips for those experiencing crashes would be mostly welcome.

Thanks for your help!

A 5 minute long project with 18000 frames?

How about creating one small project for each single take?

Try to use "quick mode" or "minimal" in IClone instead of hiQ render when working with multiple Characters. You don't need to see all hires textures or wrinkle maps when animating , it will cost a lot of Vram.
And it will cost a lot of more when UE5 is running in the background.

It would without a doubt solve the problem but with 128 Gb or Ram and 24 Gb of VRAM and a 5950x, 16 core CPU, you would think  5 minutes is already a short project. At the moment I am using only 25% of my memory (8GB for Iclone) , this includes Unreal 5 and all apps.

I am using the quick mode but I tried the minimal mode with the same result. 

But thank you both for the feedback and help!

I have a similar setup (except that I have an Intel CPU instead of AMD) and I work with short scenes of up to a minute, but I also have frequent crashes. So I don't think that the length of the project is an issue. It's just annoying, because there is no single cause for the crashing.

Thanks for your input animagic,

What I find strange is when doing the promo video for the unreal Live link Reallusion use a video with an army of soldiers and they transfer everything with time code.
So you would think that using 6 to 7 actors is very far from creating a scene with an army of actors. 

Most of the features work well by them self but when you start using a few of them at the same time Iclone can not handle it and crashes.
For example, in my last project "VR Actor School", A single actor is dancing or doing another show while the 6 others look at him at the same time, so now you are using the "look at" feature on 6 characters at the same time. Then you adjust the transition so the head and body turn smoothly, this take a lot of computer processing. Nothing crashes until you start blending this with the motion director or adding Liveface motion on top of your basic animation.

I used Unity for 3 years and swap to Unreal  about a year ago and I can count on my 2 hands the number of time they crashed.  Iclone has great features but They have to solve the stability issue because at the moment it is only good for really basic project.  This is my humble opinion of course!

I'm also getting a lot of crashes, it does strike me as odd that it can't handle such short scenes. I have 4 Actor Core characters.

I've noticed some consistent triggers, the main culprit for me is the Motion Control Director. It freaks out if there is anything on the timeline ahead of it. Which is kind of annoying, because I'd like to have characters walk into scene but would also like do the main action first then add the walking in afterwards. I think it's linked to motion correction, or layers, if there's other stuff going on it just throws a total hissy.
I have had hundreds of crashes, I now save every time I do something and at the stupid file sizes iclone is guilty of (honestly ever heard of linked assets!?) my C drive is getting swamped.

Every project starts out fine but grinds to a halt, so I'm now splitting it out by character, not ideal when I need to animate look direction and conversations. 

This software has the potential to be AMAZING, but I find myself angry so often that I couldn't ever recommend it to anyone. I just pressed the MD button out of curiosity to see if I could work with Motion Direction into my workflow and I thought my PC was going to die. It is totally un-usable in my 4 min scene with 4 characters.

FWIW I've tried:
Moving the temp folder to another large drive
keeping objects to a minimum
no lighting keeping it to minimal

All I want to do is line up pieces of mocap and do little fixes to it then export as one clip for everything else to be done in unity. Should be simple. IT IS NOT.
