I recently experienced really strange things regarding textures in C4D. I got replaced all the textures in project with HDRI in my database. I tried to replace those HDRIs with textures that should be there. Then I closed the project and reopened it, the same thing happens. It constantly get replaced.
I don't know if this is octane problem (probably it's C4D).
There's picture attached, where you see a HDRI texture instead of plane white texture with black dot as an eye.
If anybody has any idea what might help, please

I'm using C4D R21 and Octane Studio 2021.1.6-R2
