Hello guys,
I recently had a performance issue on an Unreal project with the SpinePlugin.
I saw there were 2 similar posts regarding this:

http://esotericsoftware.com/forum/UE4-Performance-issue-after-CreateMeshSection-change-9479?p=42955&hilit=CreateMeshSection#p42955
I managed to find the cause of the problem, it was because of the collision generation for the mesh sections. I disabled this and not it works fine but I just wanted to give some more information on the issue.
On my part, at least, it was caused because of high disk usage. I attached a screenshot of the files open while the plugin was running. It seems that the Runtime Mesh Component writes a lot of files in the DDC on each update (you can check the screenshot below).
I have 2 machines I am working on, a PC with an SSD and a laptop with a hard drive. On the PC the issue is not noticeable, but the DDC cache constantly increases while a spine animation is running.
Is this because of the Runtime Mesh Component or because of the way the Spine Plugin is using it?
Thanks,
Andrei
