SetPlayerObjectMaterial with custom models/textures

[Dante-1337]

Describe the bug
Unable to use SetPlayerObjectMaterial with textures from server DFFs/TXDs.

To Reproduce

AddSimpleModel(-1, 19379, -5001, "myModel1.dff", "myTxd1.txd");
AddSimpleModel(-1, 19379, -5002, "myModel2.dff", "myTxd2.txd");
...
myObject = CreatePlayerObject(playerid, -5001, x, y, z, 0.0, 0.0, 0.0, 300.0);
SetPlayerObjectMaterial(playerid, myObject, 0, -5002, "mytxd2", "myTexture", 0xFFFFFFFF);

Expected behavior
I expected to be able to use textures from custom txds the same as i would use them from the game txds.
