Cocos uses custom material to display problems

The boss of the company just talked to me many times about this problem , But I didn't pay attention when I used it , Just record it ！
problem ： Pictures are customized material The image texture is not fully displayed after clipping
Desired effect ： The avatar is downloaded from the remote server and cut into rounded corners for display

The effect :

In the process of searching, I found that it was replaced by cocos Self contained material There's no problem , Once thought I wrote it myself material Problems arise , In fact, I learned later that the default material does not operate on the image texture , So it's okay .
Then look up the code and find it packable Change it to false Just fine .. It's too much .
Part of the code is as follows ：

loadHeadImg(){
         // Download pictures from a remote server 
         this.loadRemoteRes(UserModel.inst.getAvatar(),(error,Texture2D:cc.Texture2D)=>{
            Texture2D.packable = false;
            var sprite  = new cc.SpriteFrame(Texture2D);
            this._headImg.push(sprite);
        })
    }
