Hey emrahgunduz,
This might be easier to debug if I could see what’s happening for myself. Could you migrate your character to a blank test project and send it to me? You can either send a download link here or PM me a link.
I’m also curious why you’re doing “InRange” instead of just a less than comparison. I also suspect the fact that you’re using Time Remaining instead of Time Remaining Ratio, it is causing a conflict with the Blend time in your Blend Poses by Int node. We’ll see though.
