The object that you want your text to be applied at is even larger than the largest possible texture size (512x512) for SetObjectMaterialText. It's not possible to have a direct fix, because it's how GTA:SA loads its textures.

I suggest you not to directly apply your text on the object and leaving the object in black. Then you create another transparent object (provided in 0.3e objects) which is smaller in size that you can apply your text on it. Finally, put the text on the black board object.
