Materials become inactive for a animated object in gameplay mode

Hi there, I am currently working on a small project on unity, and I am constantly facing the same problem. I import any .fbx file (a 3d model with animation) in my project, add animation controller and materials to the model and it looks good, but as soon as I hit the gameplay mode, the model turns green, as if the materials went inactive. I have tried many different models and tried many ways to solve this but the problem persists. Can anyone please help me with what I can do to rectify this?

 

Materials don't have an active/inactive state.

If materials are missing, the model will be bright magenta, but there's no general reason why anything would turn green.

Perhaps you should post some screenshots.

 

Yeah, there's no common reason it should be doing anything like that. Maybe the animation is animating the material's color or something?

Try to narrow down the cause. Remove the Animator Controller and see if it still happens. Remove the Animator. Remove other objects from the scene. Etc.

 

On removing the Animator Controller the colours do not change. Moreover, I tried making a project with only one 3d model but the problem continues (only when I enter the play mode).
Can this be a problem of the website I am using to download my models ( sketchfab.com for .fbx format files)?

 

If removing the Animator Controller fixes it, then the problem is obviously one of the animations in it. You can use the Animation window to see what each animation does.
