Hello @LightBai and welcome to our community.

Thank you for your post. I have brought this up internally and will reply with more information once it becomes available.

Thanks!

Hello @LightBai,

I have checked internally and the InstaLOD for Unreal Engine integration currently supports Unreal Engine 5.3.2. Please let us know if there are any issues when compiling the plugin for this version of UE.

Thanks!

I have no problem compiling on UE5.3.2.
But since my project version is UE5.1.1,I want to use InstaLOD on UE5.1.1.

Hello @LightBai,

Thanks for the additional information.

InstaLOD for Unreal Engine currently supports only the latest version, Unreal Engine 5.3.2. We are working on introducing support for backward-compatible builds of the plugin, which will be available in the future.

Thanks!
