In-editor animation preview broken in 4.5

[Revenvik]

Hi, looks like i’ve found broken old feature in new 4.5 engine release.
I have a tricky solution for one of my in-game assets that i need to bend on some angle.
First, I’ve got a skeletal mesh and an animation that makes this mesh bend:

longer animation time more it bends.

Second, I place this skeletal mesh on my level, set AnimationMode to UseAnimationAsset, choose my bend animation in AnimToPlay, uncheck Looping and Playing settings and then tweak InitialPosition parameter so it bends perfectly both in-editor and in-game.

But in 4.5 this somehow was broken and now i can see my bend ‘static’ animation working in-game only.

Am I missing something important on some of new features and there is a quick workaround or is this a real bug?

Note: after reloading level skeletal meshes begin properly bending, so tweaking of Initial Position parameter starts to work, interesting…

Hey Revenvik,

This is a known issue that has been reported in our system (TTP# 345877) and is currently being worked on. I have updated bug report to include information you have provided. Thanks for report!

As you have discovered, restarting editor allows you to see Initial Position changes update in viewport. Unfortunately, you’ll need to restart again if you place another Skeletal Mesh and give it an Animation Asset. I will let you know if I see an update on this.
