Hi I’m stuck here. I need to keep track of my XYZ of the camera, and assign that information to a point later in the script. I found out that the coordinate system seems to change, but not on my point. I need the point to always stay in front of my camera, but when it starts with:
x: 7.654 y: 45.919 Z: 5183 and changes to: x: 852275.0892005145 y: 5767392.023641216 Z: 5223.5517142592, then I’m a little lost in what to do. I could use some help in getting it to keep the prober coordinates on the camera. Thanks.
