iClone 7
Not Reproducible
Issue 8014
Heavy Physics Projects Crash on pressing Rewind but manually entering 1 with Enter rewinds instantly.
After about 5 rewinds in the timeline project crashes but it doesn't crash if I manually enter frame 1 and press enter.
There seems to be a hesitation in iClone when pressing rewind.

Possible Solution:
Script the rewind to execute the same operation as if someone manually typing in 1 and pressing enter. Sometimes in coding there are more ways to do the same thing but in this case typing in 1 and pressing enter is an instant rewind.

To replicate this, just fill your scene with a lot of physics simulations. My timeline was set to realtime when the crashes happened and I'd always wait until the animation has stopped before trying to press any other buttons.

You could have reproduced this if you maxed out performance with physics props with animations rather than asked me for my project.
Hi Molly, I'd really like to help solve and test this with you but I can't afford spending that much unpaid time so for now I will settle for the work around which is directly entering 0 or 1 to completely rewind.  

I did imply that Reallusion should stress test this scenario by making  and testing a resource intensive project. My iClone installation is completely fresh (less than a month) with folder and reg clean directed by Rampa and although this issue is a bit of a hiccup, same with smart gallery that has suddenly stopped loading (error -6) I have to turn a blind eye to these and get work done.

Let me know how it goes after stress testing on your side, then we'll know or not whether it might be project specific.  With the particular project I have I'm using  both cloth physics and a chain link with constraints, displacement, smooth mesh by subdivision L1, human shader  with 4k max texture resolution. 

So just for now, I can't go through all the hoops, maybe later when things are better. Thank you.
Hi Molly, yes, the start button is the issue. I can't share my project unfortunately but it happens in any project where operations are resource heavy (physics, many props loaded with animations etc)  I have also recently had iClone uninstalled, reg cleaned and iClone reinstalled. I'm using an i7, 32 GB, RTX 2080Ti and over 30 -50 GB free on my SSD hard drive.

So entering frame 1 and pressing enter is a smooth operation but pressing start usually under 10 times causes a crash.  Also I can manually enter frame 1 but switching the Time unit in project settings to "Time" doesn't allow any numbers to be entered, I don't know if that is normal but it's very odd that we can't access it, I have audio projects in another program that allow me to label on time stamps and keep scenes organized, punching in time units in iClone would be very efficient/normal if it exists.

Hi Ascensi,

Can you provide your crash dump file to us?But there may be no useful information in the crash dump file,the project is the most useful.

Download the zip file with the link below, inside the zip you can find the description about how to generate the startup log and crash dump.
TS 的:

If the memory dialog box appears when iClone crash,try to find the dump file under.
Step1: When the AP crashes, please do not close the crash dialog
Step2: Open the Task Manager
Step3: Click the "Processes" tab
Step4: Right-click on the "iClone 7 AP"
Step5: Click the "Create dump file"

Hi Ascensi,

Dose Rewind mean to Start button?Can you provide your project file to us?You can use cloud services such as Google Drive, Dropbox or OneDrive to make the files available to us and put the link in your comment. and use Private Comment if you want to keep it private.
