When I open my file in substance painter, all the texture i have put in the model are gone . It only shows blue colour. I don't know what happened. Please help me with that. I really work hard . Attaching the ss.
Unfortunately, I'll need more information to give you a proper help. First of all, could you send me your log (help>export log..), so I can dig deeper into your project ? Are your layers still intact ? Could you share a screenshot of the Substance Project ?
In the meantime, you could try to load an autosave to see if the problem persists. You could also make sure your graphic drivers are updated.
