[Bug] SetRuntimeTextureImage

[car123609]

Summary

Client: SET_RUNTIME_TEXTURE_IMAGE (0x28FC4ECB) does not correctly load base64 data:image/png;base64,... URLs on FiveM for GTAV Enhanced.

The same Lua resource and base64 PNG images work correctly on FiveM Legacy.

The official documentation states that SetRuntimeTextureImage supports both resource filenames and data URLs:

https://docs.fivem.net/natives/?_0x28FC4ECB

This affects a circular minimap resource that creates runtime textures and uses them to replace radarmasksm and radarmasklg. On Legacy, the circular mask loads normally. On Enhanced, the mask does not load correctly, which can leave the minimap missing, incorrectly clipped, or allow the GPS route to render outside the circle.

Using Citizen.InvokeNative(0x28FC4ECB, ...) produces the same result.

Steps to Reproduce

1. Add this to a client.lua:

local testImage = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAIAAAACCAYAAABytg0kAAAAFUlEQVR42mP8z/D/PwMDAwMTAxQAAC4IAwEDGOY5AAAAAElFTkSuQmCC'

CreateThread(function()
    local txd = CreateRuntimeTxd('base64_texture_test')

    local texture = CreateRuntimeTexture(txd, 'magenta_square', 64, 64)

    local success = SetRuntimeTextureImage(texture, testImage)

    print(('SetRuntimeTextureImage base64 result: %s' ):format(tostring(success)))

    while true do
        Wait(0)

        DrawSprite(
            'base64_texture_test',
            'magenta_square',
            0.5,
            0.5,
            0.20,
            0.20,
            0.0,
            255,
            255,
            255,
            255
        )
    end
end)

Expected Behavior

SetRuntimeTextureImage should decode the base64 data URL, return success, and replace the runtime texture pixels. Its behavior should match FiveM Legacy and the documented native behavior.

Actual Behavior

On GTAV Enhanced, the base64 data URL is not decoded correctly.

@Gogsi Hey just tried on the new build 94. and seem to be getting the same error?

On legacy this doesn’t happen

[Gogsi]

Yes I confirmed it still happens

[manups4e]

the resource in question, is my rounded minimap.. which loads the rounded textures on runtime.. i'm testing it now and it still happens
i can provide the script to the elements if needed :)
