HI,
I read the related posts, but nothing similar .
My model is complete, i tried to apply textures, but its is only colorized. For example, the wall with bricks is just “brown red”
Thanks for your help.
Either the scale of your model is so big the texture isn’t showing or you have the face style set to shaded rather shaded with textures.
Adding your model would give us a chance to give an accurate answer.
Are you using a style that shows textures or just simple faces?
My bad, scale issue , solved 
Thanks a lot
