Why dui render like that?

Hi, i was trying some dui today but I have this problem that i don’t know how to fix, would anyone know how to help me?
the problem is the semi-transparent edges

Well, you should provide us with your current code, it’d be much easier to spot the problem.

local cache = {}

function LoadScaleform(dui3dHandle, scaleform)
    local scaleformHandle = RequestScaleformMovie(scaleform) -- Request the scaleform

    -- Wait till it has loaded
    while not HasScaleformMovieLoaded(scaleformHandle) do
        scaleformHandle = RequestScaleformMovie(scaleform)
        Citizen.Wait(5)
    end

    -- Save the handle in the table
    cache[dui3dHandle].scaleform = scaleformHandle
end

function StartupDui(dui3dHandle, url, width, height)
    local txd = CreateRuntimeTxd('txd') -- Create texture dictionary

    cache[dui3dHandle].dui = CreateDui(url, width, height) -- Create Dui with the url

    local dui = GetDuiHandle(cache[dui3dHandle].dui) -- Getting dui handle

    CreateRuntimeTextureFromDuiHandle(txd, 'txn', dui) -- Applying the txd on the dui

    if cache[dui3dHandle].scaleform ~= nil and not cache[dui3dHandle].txd then
        PushScaleformMovieFunction(cache[dui3dHandle].scaleform, 'SET_TEXTURE')

        PushScaleformMovieMethodParameterString('txd') -- txd
        PushScaleformMovieMethodParameterString('txn') -- txn

        PushScaleformMovieFunctionParameterInt(0) -- x
        PushScaleformMovieFunctionParameterInt(0) -- y
        PushScaleformMovieFunctionParameterInt(width)
        PushScaleformMovieFunctionParameterInt(height)

        PopScaleformMovieFunctionVoid()
        cache[dui3dHandle].txd = true
    end
end

-- Native
function Create3dNui(sfName, url)
    local dui3dHandle = tostring(math.random(0, 9999))

    cache[dui3dHandle] = {
        dui = nil,
        txd = false,
        scaleform = nil,
        show = false,
        coords = nil,
        scale = nil
    }

    -- Auto load the scaleform
    LoadScaleform(dui3dHandle, sfName)

    if url ~= nil then
        StartupDui(dui3dHandle, "nui://"..GetCurrentResourceName().."/"..url, 1920, 1080)
    end


    -- Class to return
    local class3d = {}
    class3d.__index = class3d

    class3d.init = function(self, url, width, height)
        StartupDui(dui3dHandle, "nui://"..GetCurrentResourceName().."/"..url, width or 1920, height or 1080)
    end

    class3d.show = function(self, coords, scale)
        cache[dui3dHandle].coords = coords
        cache[dui3dHandle].scale = scale or 0.1
        cache[dui3dHandle].show = true
    end

    return dui3dHandle, setmetatable({}, class3d)
end

-- Main
Citizen.CreateThread(function()
    while true do
        local ped = PlayerPedId()
        local pos = GetEntityCoords(ped)
    
        for k,v in pairs(cache) do
            if v.show then
                local scaleformCoords = vector3(v.coords.x - 1, v.coords.y, v.coords.z + 2)
                local  scaleformScale = vector3(v.scale*1, v.scale*(9/16), 1)
                
                if v.scaleform ~= nil and HasScaleformMovieLoaded(v.scaleform) then
                    --                            handle           coords            rot      unk        scale      unk
                    DrawScaleformMovie_3dNonAdditive(v.scaleform, scaleformCoords, 0, 0, 0, 0, 0, 0, scaleformScale, 0)
                end
            end
        end
        Citizen.Wait(5)
    end
end)

so you have any idea?

No I never messed with DUI’s before sorry, I only said that so someone who actually knows about these would easily spot the issue.

Did you find an answer to this? I’m having the same issue where the borders are a gradient. it’s really annoying…

nope :frowning_face_with_open_mouth:

news ?

no, for now

That’s weird - this should’ve been fixed as of fix(nui): correct for premultiplied alpha in DUI blit · citizenfx/[email protected] · GitHub this January.

Did you ever provide a full repro for this at all, in case it isn’t fixed? That code was a bit incomplete.

you can find a working example here: utility_lib/native.lua at main · utility-library/utility_lib · GitHub

here is the rendering part utility_lib/main.lua at main · utility-library/utility_lib · GitHub

if i rewrite the same code in js works perfectly, in lua that happens.

Use floats where designated as required by the native site. Your call to DrawScaleformMovie_3dNonAdditive is providing integers of 0 for the “unk” variables, the center variable is sharpness as far as I can tell from DrawScaleformMovie_3d, so the “unk” variables should be 0.0, 1.0, 0.0 I believe. Someone is testing this and initial tests with floats showed proper edges. They are testing the rest of their DUI now

thank you, i tried it and it seems to work perfectly, back in the day i didn’t know that “number” in the natives means float or int, actually if i would have put my hand to it again now i probably would have also succeeded, but thank you very much for your answer and your deduction.
may i ask you kindly what is your name on github, at least i also give you credits for the answer :wink:
