How do you go about creating realistic planets?

The title says it all, how do you do it? I want that nice glow to the planet too but just don’t seem to find any posts on how to do it.

I believe that is just a mesh with an earth texture over it, as for the glow effect, I found this quick tutorial. I’m sure there are better ways to do it but this is pretty simple to follow:

Though, that might work on a smaller scale, it might not work on a larger scale. I’ll try it out anyways.

Since it is a sphere, you could more than likely just make a sphere the same size and then make it the smallest bit bigger so the earth mesh is on top. However the glow effect should penetrate the surface of the mesh.

Yeah, as I have predicted, doesn’t work. Screenshot by Lightshot

The idea of creating a glow effect of that sort is fairly difficult to imagine, especially with the limitations of the ROBLOX mesh system at the moment, however there are two possible solutions for this.

Cel Shading

An effect fairly similar to this, though not entirely accurate is Cel Shading. With some edits to the color of the mesh used for the Cels, you can create a nice drop-shadow effect that can accomplish your goal. Here is a youtube tutorial on cel-shading in roblox.

ForceFields

Forcefields is a bit of an interesting option when you’re creating this because it’s not exactly what you’d want it to look like, however with a planetoid most likely being a mesh, duplicating it and making a forcefield “outline” might be that little nudge you are looking for. Unfortunately, no tutorials for this one.

Neons

On top of that, making neons is always a good option, I could be wrong on this, but I believe neons glow through meshes, so making the neon brick a tiny bit smaller than the mesh should do the trick for you.

Conclusion

At the end of the day, this is ROBLOX and there’s really no way with the current systems to perfectly recreate this effect, at least not to my knowledge anyway.

You can use a billboard GUI with hollow outwards faded circle as the decal, just make it bright by using a light shade of blue (or of your choice), seen it used before.

Hope this helps.
