@Predalienator : always consider that the values you get for data from kinect are very small. you need to amplify them in order to match neatly with your project. there are two common ways.
1 - the easiest : multiply the output with a constant value, and make the value editable so you can modify it outside of the blueprint itself too
1 - more complicated : kinect see a triangular arc. you should calculate in which distance you are then calculate based on the horizental kinect field of view how wide is it in centimeter and convert that to the maximum left and right you wanna to in you project/
@ : Actually I followed somehow the approached you mentioned already. I am able to create a mesh based on the depth image of camera with UV mapping Tangents and Normals and it is perfect. There is just one problem. for X and Y to match kinect 2 has a coordinationmapper class which convert quite easily the X,Y from pixels to centimeters. rigth now I am using constant. and since I want to use it for augmented reality it should match the exact place or the calibrating will be cumbersome. The issue is that the coordinationmapper class has many function but those of which I want are not mapped.
maybe if it is not in the plan to get included i should implement it myself
