Is UE5 supported in 4.1 branch? I can't find 4.1 beta branch

alanyi

As the topic.I exported spines through a 4.1 version and I think I need to use 4.1 beta runtime as said in the forum but I couldn't find the beta branch but the default one. Can I use the 4.1 branch instead? I tried integrating the plugin in UE5 but an exception is generated.

UE5 is supported by spine-ue4 (we'll eventually rename it to spine-ue). Spine 4.1 has been released, so there's no 4.1-beta branch anymore. Using the 4.1 branch as you do is correct. You also must export your skeletons from Spine Editor version 4.1.x (not 4.1.x-beta).

As for the crash log, it looks like parsing your exported .skel file fails. If you have exported it with Spine Editor version 4.1.x, then this is a bug. Please send that file plus the atlas files and I can take a look in that case.

I extracted some spines from an exsiting game and export it under 4.1 to test the plugin. Here it is.

Mario

That's not a valid 4.1 skeleton file, despite it's version being set to 4.1.08. The 4.1.08 Spine Editor can't import it.

RyuMaster

I get the same error about region not being valid. I guess my test skeleton is too simplistic and misses something important?
I am using latest version of Spine, checked inside editor

Mario

Your skeleton loads fine with the latest spine-cpp from the 4.1 branch on GitHub. Please make sure you copy over the latest sources to your UE project as documented here:
spine-ue4 Runtime Documentation: Updating spine ue4 Runtime

RyuMaster

Very odd, no matter what I try, I always get this error. But it works for you, hmmmmmmm, I wonder where out setup differs. I will continue trying on different PCs and clean UE project, if it works, then will start from there

Ah, ok, it worked now. All good, thanks ^^

alanyi

It's juse werid that I got the similar error when I tried another one for testing. However, the old one whicl alreay was imported is working fine.
Fatal error!

That's not a valid 4.1 skeleton file, despite it's version being set to 4.1.08. The 4.1.08 Spine Editor can't import it.

It seems that the export functionality is not that stable. I used the old one and export again and I got the same error again

Mario

Sorry, I can't quite follow what you are saying. Could you please list the exact steps you took to get the new error? The editor export is very unlikely to have any "stability" issues.

alanyi

I think there maybe something to do with having multi version of spines on my machined. Most of my testing spines skeleton are 3.85 version and I opened them using 4.1 spines and exported them successfully but 9/10 times they are failed to be loaded into Unreal given the old error many times and the new error once. Could you please explan what version actually the skeleton is ? despite its marking itself 4.1 version.

Mario

I can't because I do not know what exactly it is you are doing. A skeleton exported from Spine Editor 4.1.x should always work with spine-cpp and spine-ue4 from the 4.1 GitHub branch.

As I said in my last post, please list the exact steps you took to get the new error.

alanyi

As I said, I opend a spine project which was 3.8.x, save it with 4.1 and exported as 4.1 as well. The problem is, which as you said before, the skeleton could not be loaded back using 4.1, which also accounts for why it can not be loaded in runtime. It's just weird.

Mario
