Hi
Recently I made anim blueprint for skeletal mesh character, with states and functions. Everything work great when I test while playing in editor.
Unfortunatelly in package game only one animation works - idle, which is not even set to idle state. I can walk waround, jump, but all this time only
idle animations is playing.
In log, I saw warning related to anim graph.

I tried package game with development configuration and shipping configuration - bug occurs in both versions.

Any idea how to fix it or work around?

Maybe it’s the same like that bug - https://answers.unrealengine.com/questions/158355/no-animation-caused-by-a-simple-setup-demo-project.html

Will this be fixed in 4.7?

thanks, Marcin

Howdy hamsterPL,

Thank you for reporting this issue. I am going to need a bit more information before i begin looking into this issue. How would you currently have your Animations set up in your Anim Blueprint? Is it correct that you are packaging for Windows?

Any additional information would be greatly appreciated.

Thanks and have a great day!

Hi Sean
Yes I’m packaging for Windows.

I have one locomation pose and one event graph. In event graph I use event dispachers which are set up in character BP.
I attached couple screenshot so you can look at part of that setup.
If you need anything more specific, let me know.

Howdy hamster,

I have attempted a quick repro of this issue and have been unsuccessful so far. Would you be able to share this project with me or a sample project so that I may be able to recreate this issue internally?

You can always send it to me privately via the forums. Here is a link to my page: https://forums.unrealengine.com/member.php?4890-Sean-Gribbin

Thanks!

Hi Sean
I’ve beed trying to reproduce this on new project with the same skeleton, and no result. Basicly I’ve been messing with this for a while I could not find a repo steps :confused:
Suprisingly, I packaged project once again, without change from previous packaging - and it worked! Animations works fine both in shipping and development builds, so it is resolved by accident.
Although what could happen - in anim blueprint in event graph, I have a is valid node at the start. When animations didn’t work, character behaves like could not get the pawn, like it is not valid. Unfortunatelly I can’t check it again because it works. I would not know how to resolve this anyway so you can give me a hint :slight_smile:

Howdy hamsterPL,

Glad to hear that the issue has been resolved. I am still unsure as to what could have caused the error. It is possible that the packaging process threw a on-shot error. If you do run into this error later on in your development, Please feel free to reopen this issue so that I may further investigate.

Thanks and have a great day!

What is on-shot error? Did you mean one-shot/one time occured?

You would be correct. Sorry about that mistake. One-Shot would be the correct word there. It is hard to say why that error occurred previously, especially considering that it is working now.
