Ive imported a model from blender (I tried all types but it’s the same issue) and when I added the texture to it, it turned the whole object into a single color. Here is some things ive noticed :
Console said that there was no normals and it tried to recalculate them.
The textures is in the material component.
Yes, there is a light in my scene…
Thanks for the help 
If that color is bright pink that mean you don’t have that texture inside projest. Just grab it from folder and leave in project folder then apply into model. If that’s not helping please give us some screenshots.
