UE 5.1 Crashes when pasting via the "Copy Regular Cameras"

[vexe]

Hi there hope you had nice holidays!

Updated our project to UE 5.1 and I noticed that the Copy Regular Cameras doesn't work anymore, UE just crashes with:

(I'm running Plugin version 0.3.1, Blender 3.1)

Hello @vexe,
Thanks for the report! I fixed this issue for the next update.
You can try the last dev branch here: https://github.com/xavier150/Blender-For-UnrealEngine-Addons#download-and-installation-from-dev-branch

• Add support NearClippingPlane in camera export.
• Fixed: Copy Cine Cameras return Regular Cameras.
• Fixed: Crashes when pasting via the "Copy Regular Cameras"

I will close this issue after the update release.

Wow thanks for the rapid response xavier, will try it out and let you know!

Hi, it still seems to be crashing? Same line number and error.

I double checked that the clipboard contains the newly updated paths from your commit, and it seems correct

Is there some quotes missing somewhere? I'm not familiar with Unreal's paste format

[vexe]

The "CurrentFocusDistance" is repeated twice, not that it matters for this but just to let you know.

OK sorry my mistake, it does work. For some reason blender added the 0.4.0 version as a separate plugin, I had to disable the old one and enable the new one.

Okay, no worry thanks ^^
