engineImageLinkTXD function incompatitible with engineRequestModel

[JeViCo]

Describe the bug

I tried using both IMG functions & engineRequestModel and failed. I tried using engineImageLink* functions like engineImportTXD and engineReplaceModel:

local imgElement = engineLoadIMG("img/admiral.img")
engineAddImage(imgElement)

local saModelId = getVehicleModelFromName("admiral")
local reqModelId = engineRequestModel("vehicle", saModelId)

engineImageLinkTXD(imgElement, "admiral1.txd", reqModelId)
engineImageLinkDFF(imgElement, "admiral1.dff", reqModelId)

Textures didn't load so i followed the wiki and changed code to

local imgElement = engineLoadIMG("img/admiral.img")
engineAddImage(imgElement)

local saModelId = getVehicleModelFromName("admiral")
local reqModelId = engineRequestModel("vehicle", saModelId)

local txdId = engineGetModelTXDID(reqModelId)
local dffId = reqModelId
engineImageLinkTXD(imgElement, "admiral1.txd", txdId)
engineImageLinkDFF(imgElement, "admiral1.dff", dffId)

I don't know why does it require additional API calls instead of direct id pass but it works.

TL;DR; after doing some researches i've managed to freeze client. I requested id for two vehicles with same parentId. I noticed that engineGetModelTXDID returned same value for both ids. I attempted to change vehicles's model with one of requested ids and my client froze.

Steps to reproduce

1. Create two or more ids with engineRequestModel function with same parentId
2. Link all ids to IMG
3. Try passing any requested id to setElementModel function

OR

1. Use sample resource
   img_test.zip

I also discovered engineRequestTXD function but the syntax is completely different from engineRequestModel. It also might have conflicts within 2 IMG archives when using same name. In short, it doesn't seem to fit the current case.

Use

Isn't it for existing TXDs?

I've made some tests around EngineRequestTXD and it actually works. Just use different string every time you need a fresh TXD id.

Personally, I'm not a big fan of those additional ID changes as this adds additional complexity and general confusion of how things work
