Angle wrapping bug

[anonymous_user_da3eeb4f]

Hi everyone,

I have been trying to rotate a skeletal mesh bone by using an Anim graph for which I only feed the yaw values(these are normalized), but sometimes I get 360 degree flip to get to that point when it tries to move from 180 to -180 instead of going same direction.

Please someone tell me what I am doing wrong? I am new to unreal. Let me know if you need any additional information.

Hi everyone,

I am new to Unreal engine, in one of tasks I have to update a skeletal mesh animation using anim graph. In this graph, I have a problem when I my skeletal mesh does a rotation by switching from 179 to -179 where its jumping by 100 or 150 degrees for a frame and return back to its actual value. I tried to debug my values which I am feeding, and they are all seems to be fine which are wrapped between -180 to 180 using Unreal NormalizeAxis. Any one have ideas what could be the reason for this bug ? So I can figure out where I am doing wrong.

Please let me know if you need any additional details.

Thanks

Thanks

Can you show us how are you feeding your angle to the bone?

Yes, I am just calculatig the Yaw and pitch from a chracter, and then feeding these values to a rotator that sets these values to the skeletal mesh bone. I have attached the screen of my anim graph, please take a look and let me know.

Thanks

PS: For some reason, I could not see this thread before so I created another one at animation section. Here is that thread also where I have added some info : Anim graph lerp issue - Character & Animation - Epic Developer Community Forums
