Tycoon C++ Track presets01 Jul 2019
- Testing partial track presets, so you can quickly place your favorite loopings. Currently set to work with a specific track length only.
Regenerating Normals and Tangents after deformation
- I have to update the normals and tangents after deforming the track piece, this process can be slow on larger meshes. To solve this I run the normal generation as an Unreal background task: https://wiki.unrealengine.com/Using_AsyncTasks
It is only possible to update geometry on the main game thread, so I cache all the generated values and re-run the update on the game thread every few seconds. The result is a nice streamlined workflow where the normals catchup quickly after adding some pieces.
// Generate normals (new FAutoDeleteAsyncTask<TangentCalculationAsyncTask>( NewPiece ) )->StartBackgroundTask();
