This question already has an answer here:

I have created a set with night sky, stars and moons, clouds, etc.. Stars are basically particle system used inside a big sphere (which is my night sky basically) and moon, clouds are all separate objects. I use a moving camera inside the scene for my animation. I was wondering if there is a way for me to render my full night sky with moon and clouds and use it as a image material for the sphere instead of rendering each frame which takes forever?

    $\begingroup$ There are probably a couple of good methods for achieving what you want. One relatively easy method would be to move every object in your scene except the night sky objects to a new layer, then create a spherical panorama of only the night sky (as detailed here: blender.stackexchange.com/q/63177/15132). Then you would add that panoramic render back in as a HDRI environment texture. Although probably not the fastest method, it will render significantly quicker as cycles does not have to compute excessive geometry from the particle systems, etc. $\endgroup$ – Hexbob6 Nov 6 '18 at 22:50

    $\begingroup$ @Hexbob6 i think this should be an Answer. Otherwise this question will never get closed. $\endgroup$ – J.Doe Nov 6 '18 at 23:44
  • $\begingroup$ @J.Doe yes, wasn't sure if it was technically a duplicate question as my method linked to a question that had been answered elsewhere. Will add a bit more detail and convert it to an answer later... :) $\endgroup$ – Hexbob6 Nov 7 '18 at 15:21
  • $\begingroup$ Hi all, yes, using the panaromic with render to hdri texture image worked perfect. Thanks a lot! $\endgroup$ – Ratan Nov 7 '18 at 19:06
