Probe::SetFadeDistance

This method sets the probe volume edge fade. This can be used to make specified edges of the probe fade in more gradually.

Syntax

• SetFadeDistance(number distance, number face)

Example

local remotePath = "https://raw.githubusercontent.com/UltraEngine/Documentation/master/Assets"

-- Get the displays
local displays = GetDisplays()

-- Create window
local window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[1], WINDOW_CENTER + WINDOW_TITLEBAR)

-- Create framebuffer
local framebuffer = CreateFramebuffer(window)
framebuffer:GetSize()

-- Create world
local world = CreateWorld()
world:SetAmbientLight(0.05)

-- Set environment maps
local specmap = LoadTexture(remotePath .. "/Materials/Environment/Storm/specular.dds")
local diffmap = LoadTexture(remotePath .. "/Materials/Environment/Storm/diffuse.dds")
world:SetEnvironmentMap(specmap, ENVIRONMENTMAP_SPECULAR)
world:SetEnvironmentMap(diffmap, ENVIRONMENTMAP_DIFFUSE)

-- Create light
local light = CreateDirectionalLight(world)
light:SetRotation(25, 315, 0)

-- Create camera
local camera = CreateCamera(world)
camera:SetFov(70)
camera:SetPosition(8, 2.5, 0)
camera:SetClearColor(0.125)

-- Create the scene
local wall = CreateBox(world, 10, 5, 0.5)
wall:SetPosition(0, 2.5, 4.75)
wall:SetColor(0, 1, 1)

local wall2 = CreateBox(world, 10, 5, 0.5)
wall2:SetPosition(0, 2.5, -4.75)
wall2:SetColor(1, 0, 0)

local wall3 = CreateBox(world, 0.5, 5, 9)
wall3:SetPosition(-4.75, 2.5, 0)

local floor = CreateBox(world, 20, 1, 20)
floor:SetPosition(0, -0.5, 0)

local ceil = CreateBox(world, 10, 0.5, 10)
ceil:SetPosition(0, 5.25, 0)

local drag = LoadModel(world, remotePath .. "/Models/Stanford/dragon.glb")
drag:SetScale(0.1)
drag:SetColor(1, 1, 1, 1, true)
drag:SetReflection(false)
local mtl = CreateMaterial()
mtl:SetMetalness(0.75)
mtl:SetRoughness(0)
drag:SetMaterial(mtl, true)

-- Create environment probe
local probe = CreateProbe(world)
probe:SetScale(9.5, 5, 9.5)
probe:SetPosition(0, 2.5, 0)
probe:SetFadeDistance(1, CUBEMAP_POSITIVEX)
probe:SetFadeDistance(0, CUBEMAP_NEGATIVEX)
probe:SetFadeDistance(0, CUBEMAP_POSITIVEY)
probe:SetFadeDistance(0, CUBEMAP_NEGATIVEY)
probe:SetFadeDistance(0, CUBEMAP_POSITIVEZ)
probe:SetFadeDistance(0, CUBEMAP_NEGATIVEZ)

-- Camera controls
require "Components/Player/CameraControls"
camera:AddComponent(CameraControls)

-- Main loop
while not window:Closed() and not window:KeyDown(KEY_ESCAPE) do
    world:Update()
    world:Render(framebuffer)
