Skybox in 3.0, a simple example, with shader.

[shadmar]

Hi

 

Here one way to do a skybox in 3.0 without interfering with editing in the editor:

 

 

--Create a camera

camera = Camera:Create()

camera:Move(0,5,-15)

 

--Create skybox

sky = Model:Create()

--just render a plane and project cubemap onto it

local surface = sky:AddSurface()

surface:AddVertex(-0.5,-0.5,0, 0,0,-1)

surface:AddVertex(0.5,-0.5,0, 0,0,-1)

surface:AddVertex(0.5,0.5,0, 0,0,-1)

surface:AddVertex(-0.5,0.5,0, 0,0,-1)

surface:AddTriangle(2,1,0)

surface:AddTriangle(0,3,2)

 

--position in front of camera but far out to near camera clip plane

sky:SetPosition(camera:GetPosition())

sky:Move(0,0,camera:GetRange().y-50)

sky:SetScale(camera:GetRange().y*10)

sky:SetParent(camera)

 

-- and paint it

skymat=Material:Create()

shader=Shader:Load("Shaders/Cubemap/sky.shader")

skymat:SetShader(shader)

skytex=Texture:Load("SkyBox/grimnew.tex")

skymat:SetTexture(skytex)

sky:SetMaterial(skymat)

Awesome work, as usual, shad! Downloading now!

Will have a look at it, see how it works, and make a few skyboxes for the asset store.

That skydrome seems to work ok. Not a very exiting sky but ok fornow.

It is a skybox, not dome and you can replace the cubemap with any cubemap you like.

Here are som extra skyboxes

The two first ones are ChrisV skyboxes converted to LE3 format and ready to use with the code above ;
