Anim Retargetting crash

Chosker · October 30, 2014, 10:23pm

hello,

trying to use animation retargetting (different skeleton) in v4.5.1 as specified in the docs, with my own skeleton. My skeleton is a Biped from 3dsmax with no significant changes (3 spine links, as many twist bones and IK bones as the Default Skeleton, and only a few extra bones of my own)

I’ve used the rig from the Engine Content into the Default Skeleton and my own Skeleton, then re-mapped all my bones to the default skeleton bones, and then changed my pose to match it (T pose) and hit Save Pose.

all seems in place so I proceed to retarget the Walk animation, but in the window where I select my skeleton I cannot see it in the Target window (see image)

if I then confirm the dialog I get a crash with the following callstack:

MachineId:5E59BB914BEE0D76E23AC9B7D71FFFF5

Hi Chosker,

I am currently working on a similar issue and we are trying to determine if it is a bug within the retargeting system. Would it be possible for you to package and send just your character/skeletal mesh assets. We’re heading into the weekend so I can not guarantee I’ll have a to look at it before Monday.

If you cannot send your files and/or in the interim, you cant try just retargeting the bones (root, arms, legs, neck, head, hands, feet) and see if it works in general. From there, you can retarget fingers, toes and try -then finally the more complex additional joints (ie. IK, twist bones, etc.)

Regards

hello,
I currently don’t have time to test this (weekend came first), so if you manage to find some time here’s my file

otherwise I’ll also test in smaller granular steps when I have some time next week

thanks for your support

Hey Chosker,

and I have talked with our animation developer and she has just recently fixed this crash internally. Once the update is tested, it will be added to a future release of the engine. Let us know if you continue to see it after we make some updates.

Thanks!

thanks for the info

when could I expect this in a public build? 4.6 I guess?

anonymous_user_bcdd396d · November 3, 2014, 2:53pm

Hi Chosker,

As mentioned, this has been fixed internally so it should be working in the 4.6 preview. If it is not working in that build, please bring this to our attention in this thread.

Thanks for your feedback!

I’m getting similar crash errors shown in my topic here: I figured you’d best know about it as I’m running on 4.6. Crashing randomly in editor - Platform & Builds - Unreal Engine Forums

Hi Daverm,

The crash here is specifically linked to Anim-Retargeting and we asked for feedback for that issue only, as the developer fixed it for the 4.6 release and we want to ensure this specific issue is no longer causing problems.

The issues of “random crashes when trying to play in the editor [that] can happen anytime from first launch to after an hour of work…” Are not related to this specific issue. I am looking into the crash you reported in the posted link and hopefully we will be able to determine the specific cause for your reported crash.
