Thanks for the file, Scott.
Please do the following: (Control/Command: below simplified as Control)
• Select everything in the Object Manager [OM]. Mouse over the OM and Control + A.
• Click on the top Solo icon on the left. (Solo Off)
• Then Control + C to copy anything from the OM
• Control + N to create a new Project file
• Safe this new scene in the folder that you have sent to me. Alternatively, in the folder where the tex folder is with all your textures.
• Then Control + V in the new file. All content from the previous project file into the new.
• Save again.
It should be fine now.
Let me know if that worked. If not, try as the first step to delete anything that is a plugin. The View-Settings>Texture option had no influence anymore. This works again in the new scene, which has its Render Preset to “My Render Setting”. In short: something has broken your file. To have zero 3rd party items for the first step is crucial.
Cheers
