Hi Juanjo,

there is a problem when using a texture in the anisotropy rotation. It's sometimes rotating at twice the speed of the object, it's assigned to. Attached is a GIF, which shows the problem, you need to open it in another tab.
In another scene I used the same objects and material and it's working as expected. I guess internally Octane needs not use some kind of inverse transformation to correctly calculate this but in some cases it does this in the wrong direction and therefore the texture spins at twice the speed instead of being static.

I reduced my scene quite a bit, it's about 60MB. How can I transfer it to you?

Cheers, Lukas

Hi,

You can send me a pm including the link to download the scene. This is really a weird issue, but I'll take a look at the scene to see if I can find the problem.

Thanks,

Thanks, I sent you a private message with the dropbox link.

Sorry, I don't have any pm from you. Can you please send it again?

Thanks,

Sorry, don't know what went wrong there. Sent again - please let me know, if you received it.

Yes, thanks. I have the scene. Let me investigate what's going on with this issue. It is something really weird.

Thanks,

Great, thanks!

I was testing your scene using the just-released Octane 2020.1.1 core that includes a lot of fixes, but unfortunately, it seems that the problem is still there. I've reported this issue to the core devs to check if we can find what's the problem.

Thanks,

Great - thanks for letting me know!
