I'm having an issue while installing this plugin, once installed it appears a window telling me:
Plugin 'OctanePlugin' failed to load because module 'OctanePlugin' could not be loaded. There may be an operating system error or the module may not be properly set up
After that message the UE5 shuts down. If anyone knows the solution pls let me know
Thank you

What version of unreal are you using?

Hello, I currently use Unreal Engine 5.3.2, and my problem is that it does not do any type of render, it is as if Octane did not exist, it simply does not do anything, neither with videos nor with still images, and for some reason when I try to open Octane's viewer gets stuck and Unreal Engine closes. The thing here is that this didn't happen to me a week ago in Unreal Engine 5.3.1.

I don't know if it could be that Octane has not been updated for this version of Unreal Engine? Whatever it is, I can't render my projects with Octane because of this error.

Any help is welcome, thank you!!!

I put out a new build that should have this issue fixed

This seems to be a bug in Unreal itself. The material function MF_HeadMask_TexArraySample has an incorrect texture sample node. When you set it to linear the material works

Hello, thank you very much, I have been using it this weekend and so far it is working perfectly, I hope nothing breaks along the way

Thank you!!!

Well... unfortunately Octane Render is currently unsuitable for Unreal Engine. Usually Unreal Engine does not use this for rendering characters or archives. This is an engine for creating an open world with thousands of textures, materials and objects. Unfortunately, Octane Render cannot work with a large number of textures and crashes. I tried to optimize the scene for four days, I even reduced the textures to 128*128, but it didn’t help.
Question to the developers: How did you test Octane in UE? On empty stages? Because in other scenes he crashes.

Going over the memory limit should not always create a crash. There might be a bug that causes the crashes that we havnt encountered during testing. Could you provide us with one of your scenes that crashes?

Additionally, work is being done for Octane to work better with large scenes in the future which would make the unreal plugin work much better.
