Unreal Engine Daz DazToUnreal modifies g8F boobs when exporting animation

[MacFromMadCat]

Hi everyone !

I have a very strange behavior exporting animations with DazToUnreal and I tried to make a minimal use case to ask your help.
I made a very standard G8F character, modifying some boobs shapes and exported it to UE5.5 (everything is ok at this step !).
Look at these gorgeous young, and a little saggy, tits :

Now, when I make a very simple animation in Daz and I export it to UE5.5, it looks like boobs are moved up and are bigger :


First, I suspected morhps or poses can be additive, so I removed every shape modification to my character and export the animation but the result is still the same !


Have you got any idea about this strange behavior ?

Thanks

Try disabling JCMs.
On another note, why are you animating in DS anyway? they don't even have working IK.
The animation tools in Unreal are so much better.

Thanks for your answer !
I don't use "Export morphs" so I think JCM is disable ?
I make animations and poses in Daz because there is a hudge library of poses and expression whereas in Unreal, I think (but I have very limited experience) there is less resources ? Do you have some insights about that ?

It's possible that your animation is affecting the pectoral bones on the G8 rig.

As Dreamy said avoid animating in Daz. You can use control rig in UE to animate.
