**Use-case** : _Spawning the same HISM along a linear | closed-loop spline_. At present, my logic is configured to loop through spline-points (placed at corners, only), measure each segment =\> Set ‘Current Segment Length’ / Spacing = int ‘Number of HISM’ to place between ‘Current Pair of Points.’ Much obliged if someone would assist me in understanding: **How can Blueprint be configured to offset towards the ‘interior,’ local to each instance ?** I cannot quite make sense of how to make proper use of the ‘Get Right Vector at Distance Along Spline’ node. ---

Hi el.ganz.andere, For a two lane road, I just made a simple function to expand from the spline, it may help in your situation: ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/5/f/b5ffa72b25ee47465fc3911c212884b5b04b5d60.png) that gets called like: ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/f/4/e/f4e0c032649b4da893b5f1890352e3c7b9549769.png)
