Hi there,

I encountered multiple crashes while working with UMotion and I suspect it might be related to how it interacts with VFX Graph assets.

I’m using this package for a sword effect

https://assetstore.unity.com/packages/vfx/particles/vfx-graph-weapon-effects-vol-1-206237

The sword GameObject (which contains a VFX Graph) is initially disabled in the hierarchy.

The crashes seem to occur more frequently when both the Pose Editor and the Clip Editor windows are open in UMotion. I noticed that once I removed the VFX asset from the hierarchy, the crashes stopped occurring.

This makes me think there may be some kind of conflict between UMotion’s editor updates and Unity’s VFX system.

Here is one of the stack traces from a crash:

Can I make full FPS Animations if I rig my arms in Unity? I just wanna make simple-ish animations but need IK from Umotion pro because blender feels so complicated.

How to detach magazine correctly doing reloading animation and reattach it?

We get warnings as shown in the screenshots below. The Callback function exists, and looks like this:

public void Callback(AnimationEvent evt) { ... }

This is a standard Unity practice. After exporting, it does work, but if you could allow it to find functions with that pattern and accept them it would be great. Thanks.

기존 애니메이션 클립에서 상체가 앞으로 기울어져 있어서, 정면을 향하도록 바로잡았습니다. 링크를 따라갔습니다.

하지만 첫 번째와 마지막 프레임에서만 상체가 똑바로 서 있고, 중간 부분에서는 상체가 옆으로 기울어져 있습니다. 이 문제를 최대한 빨리 해결하고 싶습니다.

Reimporting the models as FBX is not an option in this case. I want to use UMotion to help me pose the VRM models and make simple animations.

I want to do a very basic thing, which is, be able to animate in umotion while having audio feedback so I can accurately animate my humanoid character to the audio, is that even possible? and if so, how do I do it.

When exporting animations with the Update Existing File write mode. After the export is finished, I have to right click the FBX file in the Unity Project window and manually Re-import the asset otherwise the new animation doesn't show.

Would it be possible for you to automate that so we don't have to do that every time? Or a way I can hook into the export to do it myself? Thanks!

Hello! I figured out how to attach the weap

on to the hand - that works fine.

However, I’ve run into another issue

In the new version, I can’t figure out how to attach the weapon magazine to the other hand, so that the magazine follows that hand, and then how to detach it correctly afterward

I would really appreciate any help with this

The handles are only visible inside bones. I suspect this is due to recent changes in Unity regarding rendering in the scene view. Unfortunately this makes UMotion pretty unusable.
