Is it possible to render my scene into a skydome?

I created a lowpoly game I want the sky with clouds and mountains in the back of the scene to be in a skydome (in Unity) and just the ground with the trees and that stuff to be actual mesh.

I'm developing VR for cardboard so trying to minimize the polys in scene but .. I need control over the background, cannot just go and download a texture.

PS: I've been told that for VR skybox is not adviced and skydome is the way to go. Correct me if I'm wrong.

  • $\begingroup$ Does Unity take equirectangular environment maps? How about cube maps? If it can use either of those, see this. $\endgroup$

  • $\begingroup$ @Mentalist I've been dealing with it and I would really say it does not :( Any other clue ? $\endgroup$

  • $\begingroup$ I got curious and decided to RTFM. Unity takes cube maps, essentially. But instead of one texture, it uses 6 individual ones. This info can be found in the Unity documentation. So you can simply follow these steps up to the part about compositing, and stop there because instead of compositing you will load each of the 6 images into Unity individually. $\endgroup$

  • $\begingroup$ As for a "skybox" vs a "skydome" where VR is concerned, the most info I was able to find with a quick search was in this thread on the Oculus forums. Read the comment by user Pyry. And as a result of what I read there I then found this other thread discussing a Rift-specific skybox. I don't know much about Unity or Oculus, but I know that Unity supports cube maps, so why don't you try that and let me know how it goes? I'm curious too. $\endgroup$
