I have this issue since a while and I don't know why I experience this.
Sometimes C4d crashes when using octane and when I restart the program it is impossible to relink the textures.
All path are good, I use the Asset Inspector from C4D. After relinking, all texture path appear ticked green but as soon as I move camera or play one frame, All texture path go back to red automatically.
Octane texture nodes say "Error loading texture".
I don't have any other choice than manually dive into all the image texture nodes and import back the textures, which is pretty annoying and time consuming on big projects.
I joined a BugReport.zip
Thanks for the help.
