In older games Ive made levels in, like unreal or half-life the skybox is a parallaxed texture that you assign to world geometry, for instance, the ceiling of your room, to give the illusion of the room being open to the sky.
There are some neat tricks or weird things you can achieve with this 'sky portal' method. For example you could have 'sky' in an underground room. or walk through a hole in the sky.
I'm wondering is it possible to make a mesh in unity3d render as part of the skybox like in these older engines.
You can do this yes. Usually you assign a "SkyBox" to your camera and change the "Clear Flags" for her "SkyBox". However, there are other ways to do.

Hope this help !

To be more precise I need a type of lighting that looks good to put on building models that already have a texture, I can't texturize the textures with light turned on apartments such as in GTA5 because I do not know how to create textures. I tried putting point light and spot light on buildings but it looks pretty bad, neon cubes are not good either as it makes the building look back.
I hope you understand what I meant.
Like that but no texturization
To achieve the results in the image, you should use an emission map.
Creating these types of lights using the Light Component is inefficient. You must not Spot Light OR Point Light for this purpose.

I'm having trouble figuring out how to light up large area(s) of sprites in Unity 2D. My previous knowledge on Unity's lighting is zero.
I first tried using a large amount of point lights and using the "Sprites/Diffuse" material, but about only five would actually render at a time, so I guess there's a limit on that.
Then I tried putting in an area light. That didn't do anything, so that's when I started doing research about baked lighting on sprites (and baked lighting in general). I found stuff like this but I couldn't get it to work either because it's outdated or because I don't know what I'm doing. Other answers I've come across seem to assume that the reader knows anything about lighting in Unity in the first place which, to be honest, I don't. Unity's documentation website had some information on it, but no tutorials that go into how to set up baked lighting.
I've tried a bunch of different combinations of materials (like using the "Standard" shader for the sprites instead of "Sprites/Diffuse", emission, ect.) and I enabled "Baked Global Illumination" in Lighting>Settings.
If baked lighting isn't possible on sprites (or isn't worth the trouble), what are the alternatives?
Edit: I made sure not to have the lights pointing the wrong direction, and I do realise that Unity2D is just like painting onto a piece of paper in Unity3D. I was able to get point lights to work, but only a few at a time. I don't need to do the entire screen at once, I need to do a large specific area at once.
some tips...
working with sprites your in 2d... when you add a light, switch to 3d mode, and rotate to make sure your light is pointed at your objects, and oriented so as not to be on the same plane, or level with them, as this will cast all the light behind them.
if your trying to light up everything on the screen(in camera) attach an area light to the camera at the cameras position, point it where the camera points, and then in the inspector on the right, you can change its variables. intensity, range, width, height etc.

For some reason, I never even thought about going into the asset store. I found this for free, and it looks like it will work: Light2D.
I'm making a 2D sandbox game like "Terraria" and "Starbound". This is my game
The light is filling the whole terrain but i don't want it. I want following:
You're probably using Directional Lighting, which illuminates the whole terrain equally in the direction you made it.
You could use Spot Lights or Point Lights, which will illuminate only the surface you want to.
Edit: although using this method, this could take way more resources due to the number of single lights placed throughout the map.
I'm making a FPS game in Unity, and I want the environment to light up as the player is shooting on his environment.
So say I have a tree. First it would be entirely black or greyish, but if I shoot somewhere, I would see some green.
To accomplish this feature, I'm using a raycast to have the impact point and so I can access any renderer of the point that the player is shooting on.
I guess the next step would be to write a custom shader to light the exact pixel that is shot.
Do you have any idea how I could write this shader or another way of doing this effect?

If you are using deferred rendering: Deferred decals.
If you are using forward rendering: Projectors.
If you need some more advanced "paint-like" functionality, use render textures coupled with RaycastHit.textureCoord to get the exact UV coordinate at your ray intersection point. You can draw stuff to render textures using Graphics.Blit. Check out this github project for some inspiration on how to do this.
I am working on game in unity in which i need some images to be placed on terrain as in the attached image yellow arrows and "P in blue circle" are rendered on surface in unity.
Any idea or method will be appreciated.
There's no built-in support for decals in Unity. You could just create separate gameObjects with transparent texture and place them above the terrain here, or use one of several packages for decals in Unity Asset Store, like this one. (I have only briefly tried it and can't say anything about it's quality).
I know it's an old topic - but for those who are still not satisfied:
I would recommend using Easy Decal.
It's a very powerful decal projector. It's easy to use and you can stick decals also on uneven surfaces like bumpy terrains.
You could try putting a plane with the texture aligned with the surface normal slightly above the surface. Or you could try an extension that does decals for you. This is what i found:
Decal System for Unity3D
As previously mentioned Easy decal is a good choice. It's easy to use, has extensive fuctionalities and you'll get a lot for your money. But if you need skinned decals there's no way around Decal System Pro by Edelweiss interactive. It's more expensive, but beside the skinned mesh support it also supports texture atlases which saves you draw calls.
