How can I transition between animations with opposite inputs in my blend tree?

Hey all - I’m pretty new to Unity and I’m running into a problem with animation transitions in a blend tree on a test character model.

See the attached images for my character setup (blend tree config and script):


This setup works great, except I’m finding that opposite inputs have no transition… For instance, pressing ‘A’ then ‘D’, or ‘W’ then ‘S’ makes my character jump from pose to pose with no blend.

See the following video for a demonstration: iCUE 2020.04.28 - 21.42.29.05

Is there a setting I’m missing, or a work around that I could utilize to alleviate this problem? Any help would me much appreciated!

Any help on this? I have the same issue
