Will do - I’ll post the code tomorrow for everyone to play with, just got it submitted in our local code repository today. Unfortunately it requires some C++ engine changes, otherwise I’d release it as a plugin.
Our team is going to spend the next few weeks trying it out as a whiteboxing tool for rapid track prototyping/iteration on Space Dust Racing, and I’m going to extend the idea further by allowing you to specify a static mesh for every SplineMeshComponent segment on the spline. If it works as I’m hoping it will, we can create a set of 3D road tiles, then build the majority of our tracks using tool to stretch them into shape. We’ll still have custom geometry in parts for set pieces/terrain etc., but should take a lot of the pain away for the artists!
