Make my TP camera switch to the gun's aim down sight camer

Im basically having issues with Set view target with blend node, the camera just enters my players torso

I think you may need to add more detail in what your setup is. I personally have never used this node but for other people that may be interested in answering this question, it may help to do so. I suggest going in more detail with what you have done, your desired result and your current result. Pictures also can help explain.
