Material/Texture scaling/rotating/offsetting function implementation

[raven1934]

I'd like to request addition of a function that allows players to scale/rotate/offset the models texture/material, this would greatly benefit flexibility of props by allowing scaling, rotating, offsetting the material to better fit persons use for it. Would this be possible to implement, or is there significant obstacles to it is beyond my knowledge, but I'd like to know if this is the case as this is already something found in advances material tool and pac3.

Thanks in advance,
