Question can i get inside a sphere object?

Hi
I am trying to create an area of my scene dedicated to space. I want to be able to put a material onto e.g. a sphere, then inside the sphere, I would like to have various objects.

I am guessing that isn't possible so what is the best approach? I do not want to leave the scene and the rest of the scene is in daylight. I looked into skyboxes but i think these need to be scene dependent?

thanks for any ideas on how to approach

 

Steps to success:

- make a sphere in your favorite 3D modeling program

- get inside it

NOTE: beware that generally polygons only render on ONE side, so when you make your sphere, flip all the polygons so they face inwards. Here's how to see this as you work in Blender:

 

For his purposes @Kurt-Dekker that will be fine because the player is never going to go outside the sphere in this instance to begin with. This is a method I'd been looking at myself but hadn't had time to research properly as I'm focused on other stuff right now so I'm glad it came up, didn't realise all it would take is some flipping in 3D software.

 

You can actually even do it at runtime or import time or wherever you like within Unity... you just need to wind the triangles in the opposite direction:

If you have a triangle with indices

0, 1, 2,

It just needs to become

2, 1, 0,

 

ok so i can do this with an imported sphere but not a gameobject sphere?Only problem there is that I have no idea how to use a 3d editing app.. have downloaded blendr and seeing what I can work out but if there is a way to do this in unity that would be welcome

-I do need to TP into and out of the sphere but assuming that won't be a problem?

 

You can use a two sided material on the sphere.In HDRP/Lit there is a checkbox for double sided. For Lightweight render engine, there is a dropbox for Render Face. Various ways for different pipelines. You can also take an existing built in shader and modify it to be double sided.

 

thanks - that did it
