Currently what I am attempting to do is load the texture to a temporary placeholder and then applying it to the Model.
Here is what I have:
In the Load function I have:
Room = Content.Load<Model>("wall");
RoomBG = Content.Load<Texture2D>("Denimtexture");
And in the Draw function within the game:
effect.TextureEnabled = true;
effect.Texture = RoomBG;
The application of the texture in the draw seems to throw an exception.
After further testing it seems the "effect.TextureEneable=true" is where it throws the error as the "effect.Texture=RoomBG;" is OK if alone.
