ok guys so i found a way …
i remove the transparency from my matterial
i’ve created a layerd shader , left just 1 layer in the shader on that i connected the blinn shader ( the leaf matterial ) to the color and on transparency i’ve added the mask of the leaf . and changed composit flag from layer shaded to layer texture , assigned the layerd shader to the leafs and work , tought it how to do it last night , first i had the idea to do the same thing with a surface shader , but i tested it and doesn’t work , but with layer shaded works very nice , now no more reflection and specularity in unwanted areas of the object .
Maybe this can help those who look up on the internet for a solution .
