I have just made my render but I cannot see the background in my Rendered Image. I have already added it to the "camera perspective" but still cannot see it in the rendered image. Please help me because I really want my render to be perfect...
If you use Cycles for rendering you can add a background after having finished rendering using the compositor. You'll need to render with a transparent background. To do so you have to check 'Transparent' in the Film settings of the render tab.
For compositing you can follow the steps explained in this question.
There are multiple ways to achieve this. But the simplest way is to use the "import_images_as_planes" addon.
Just enable it from the preferences. Then go to the import >Import images as planes.. And choose your BG image.
This week bring in a plane into your scene with the image perfectly mapped onto it. Now you can change the material and position etc to get the best effect you need. Hope this helps.
