Yes. Simply create some kind of int or boolean in a config file and then simple set the texture according to that value. If you don't really know how to do it I suggest learning some more basic Java.

How Create a 3D item? for Example a Sword, I need add a 3D Sword in my mod, As i do (I need the code, model the swords is very easy), and the code for put the Sword in the hand of Steve, but only if you can, but only the code for the sword to add...

No, it's because Mojang could sue them until their great-grandkids are bankrupt. If it were legal, a mod like, say, Twilight Forest could easily charge $5 per download given how much content it adds to the game. I'd love to see a modder try this.People, just remember that modders have a vested interest in ignoring and shouting over any evidence that suggests that they cannot win a lawsuit against you, or that they would lose a lawsuit if they tried to sell their own mod, which would indicate ownership.This is only relevant because to many people unfamiliar with legal proceedings, the threat of legal action is functionally equivalent to legal action itself.

• make commercial use of anything we‘ve made;
• try to make money from anything we‘ve made; or
• let other people get access to anything we‘ve made in a way that is unfair or unreasonable.

They could also directly sell them if they wished to.
