Thats a problem with engineRequestModel in newer client versions.

... -- requesting
nameToModelData[name]["newID"] = engineRequestModel("vehicle", basedModel)
nameToModelData[name]["txd"] = engineLoadTXD(txdName)
nameToModelData[name]["dff"] = engineLoadDFF(dffName)
engineImportTXD(nameToModelData[name]["txd"], nameToModelData[name]["newID"])
engineReplaceModel(nameToModelData[name]["dff"], nameToModelData[name]["newID"], true)
return nameToModelData[name]["newID"]
... -- changing model
local newID = f.requestVehicleModel(customModel)
if not newID then
    outputDebugString("Custom cars: nie zwrócono newID.", 1)
    return
end
setElementModel(vehicle, nameToModelData[customModel]["newID"])
outputDebugString("Custom cars: podmieniono model na "..nameToModelData[customModel]["newID"].." dla pojazdu o ID "..dbid, 3)

It shows in debugstring as loaded correctly, but model doesn't have valid model and textures are broken.

Please be specific about the build you're running, @MrDadosz

I'm using v1.6-release-23690 and tested this with newest nightly v1.6-release-23728 - still the same issue. Some users reported that problem on MTA discord and it was bugged since 2025-12,

Additionally, the game currently crashes or freezes very frequently, especially when reconnecting. Weak computers have a large memory leak in the VRAM and now it doesn't load images created with DX functions for those players. GTA shows an error with loading a model that worked correctly from 2022. The problem isn't just with models, but also with textures. Textures that worked on a model for many years are now replaced with various others from other models.

Probably connected to #4635
