I have migrated a project from UE4 to UE5 and a car mesh that uses UDIM textures now wont render correctly with the octane plugin. It looks fine in the viewport but when I try to render it looks like the texture is mostly black. It could be inverted but Im not completely sure. I have alos noticed that resizing UDIM textures in editor does not affect the rendered output, so even if I rescale an 8k texture down to 128 it will still use the same amount of memory.
Is this a bug in the current plugin version?

UDIMs are currently working in our test scenes.
Would you mind sharing a scene where it is not working correctly?
Are you using the 'Maximum Texture Size' option to scale down the textures?

Coudl you tell me where to find the 'Maximum Texture Size' option. Perhaps that is the issue.

Sorry, I asked about the maximum texture size, because it is not supported for UDIM textures right now.
Could you please show me how you resize UDIM textures in the editor?

Aha, that makes sense then. I was using a mixture of maximum texture size and texture LODs. Well that's one mystery solved.
Still not sure why my UDIM texture does not look the same in the UE5 release of the plugin vs the UE4 (UDIM supported) release.
