Texture Problem in Blender

Hi there !
I’m begining in Blender and I have a huge problem. I created a Mars planet with Blender using a texture picked on internet. I also added a rotation movement to my object. But when I export my project as a video, the texture is not shown and my planet is all in grey. I want to use that for a video so it is very unnerving… I think I am doing anything wrong…
Can somebody help me please ?
I am new on this forum so I can’t put my files as attachment but I will do it when I can…
Thanks for your answers,
Tony

Hi Tony, check in the shader viewport that your image is linked:

A couple of things…As @digitvisions said to check if the texture is linked… also have to add light to your scene? No light = Grey …add a sun lamp or area lights…as you are new…Check on Youtube on how to use HDRI lighting and to use an HDRI to light the scene but still have it look like space, you need to not show the HDRI in the render so set up with this node setup

Thanks for all these informations.
How can I display this window surrounded in red ?
I have already add light in my scene ; I have placed the default projector where I wanted it… Should the object be illuminated using other ways of doing this?
Thanks,
Tony

Add>texture>image texture.

Thanks a lot for all your answers. In fact, an old version were installed on my computer and that seems there was a bug. I upgrade Blender and it’s working !
See you soon,
Tony
