[1.8] render a custom arrow ?

good days

i been creating a custom bow and a custom arrow,

the bow is ready

item arrow its done but entity arrow, I have the code, it does less damage than vainilla arrow but more speed i can pickup this custom arrow but

dont get how to make it load a texture is invisible

soo the first question is , this is 1.8 the render must be a json file or a techne model ?

then how i declare it in this entity arrow class

and i been reading thath the renders for entities must have entraces in the proxy files

im like newbee whit this of proxy's

well thankyou.
