I recently downloaded this model to make animations in Blender 3.0 https://www.deviantart.com/jorjimodels/art/Funtime-Freddy-Release-732345375
However upon loading it into Blender 3.0, all of the textures that are meant to be there have been replaced with plain colours, like the eyes.
I then loaded the model into Blender 2.79, and in 2.79 the eye textures load perfectly as intended.
This is what the Blender 3.0 eye 'texture' looks like.
And this is what the Blender 2.79 (correct) eye texture looks like.
I have searched everywhere for an answer to this question, and I am aware it is an issue with the blender rewrite in 2.8+ but I am yet to find a working solution for this problem.
The model can be found on google drive, note that I do not own this model, nor do I claim to.
