Got the Spline Tool basically working to create a river system for my map generator. A few additions to the tool would make things work even better:
Spline Merging/Branching. Need a way to have Spline Components with multiple branches. I can drop splines on top of each other, but the overlapping meshes have lots of visual artifacts and don’t necessarily fit properly. It would be better in general if the Splines worked in a coherent branching fashion anyway.
Spline Mesh World Points. Using multiple meshes leads to tiling which is very obvious, especially with water textures. Would be great if we had a third option that combined the Spline Mesh Component with the Spline Component so that we could tinker with the tangents at multiple points along a single Spline Mesh instead of only Start and End.
Spline Instancing. Need an InstancedSplineMeshComponent to reduce draw calls. Preferably one that works with the above features.
